Abstract:
One of the predetermining factors to perform minimally invasive rhinosurgery successfully is the searching for optimal surgical access areas, the choice of which at present mostly depends on the visualization capabilities of endoscopic devices. The angular vision is one of the important factors for planning and performing endonasal interventions on the anterior maxillary sinus. A large viewing angle allows surgeons to expand the potentials of minimally invasive access, reduce the need to replace endoscopes with different angles during the intervention and improve the quality of the surgical procedure. The purpose of this study was to improve the method for selecting surgical access to the maxillary sinus, taking into the optical axis and the actual size of the field of view provided by the endoscope. The simulation of the process of selecting the optimal option for access to the maxillary sinus on the basis of our own method of predicting the visualization of the lumen in the sinus was performed. To determine the actual viewing angle of the endoscope, we compared the application of the standard methodology and the approach we elaborated. 3 endoscopes with a 70° optical axis orientation were examined; the studies were performed three times. We found that the results of determining the boundaries of the field of view according to our technique and to the method of Wang Q. et al. (2017) did not differ significantly, that indicates the comparable accuracy of both methods. With the declared identical characteristics of all three endoscopes, we revealed the magnitude of the field of view differed quite significantly (by a maximum of 8.7°). Moreover, the value of the viewing angle in all samples of endoscopes tested was greater than that provided by the manufacturer for standard endoscopes (60 °). The average duration of measuring the magnitude of the field of view of the endoscope by the method we proposed took 25.3 ± 3.2 s that was significantly faster than by the method of Wang Q. et al. (2017), 83.7 ± 2.0 s P≤0.05). We should also stress on the greater convenience of carrying out examinations according to our method. When assessing the potential of the maxillary sinus visualization, it is necessary to take into account not only the individual anatomical features of a patient, but also the actual optical characteristics of endoscopes. The device we designed for determining the boundaries of the field of view of endoscopes is easy to manufacture, requires less time for testing and enables to determine the actual viewing angles of the endoscope quicker and more effectively. Actual optical characteristics of endoscopes may differ from the standards.

Abstract:
Background: The likelihood of endoscopy-associated infections (EAIs) is often referenced from a paper published in 1993 by Kimmery et al1 in which a risk of 1 exogenous infection for every 1.8 million endoscopies (0.00006%) is proclaimed. Even though Ofstead et al2 pointed out in 2013 that this was at least an underestimation by 6-fold because of erroneous assumptions and mathematical errors, the original calculation is still often referred to. In the past decade, multiple outbreaks of multidrug-resistant microorganisms (MDROs) related to contaminated duodenoscopes have been reported worldwide. This leads to the assumption that the former risk calculation is indeed incorrect. Objective: We calculated the duodenoscope-associated infection (DAI) risk for the Dutch ERCP practice. Methods: We searched and consolidated all Dutch patients reported in the literature to have suffered from a clinical infection linked to a contaminated duodenoscope between 2008 and 2018. From a national database, the number of ERCPs performed per year in The Netherlands were retrieved. Actual numbers were available from 2012 to 2018. Numbers from 2008 to 2011 were estimated and assumed to be equal to 2012. Results: In 2008–2018, 3 MDRO outbreaks in Dutch hospitals were reported in the literature, with 21 patients suffering from a clinical infection based on a microorganism proven to be transmitted by a duodenoscope. In that period, ∼203,500 ERCP procedures were performed. Hence, for every 9,690 procedures, 1 patient developed a clinically relevant infection (DAI risk, 0.010%). Conclusions: The risk of developing a DAI is at least 30–180 times higher than the risks that were previously reported for all types of endoscopy-associated infections. Importantly, the current calculated risk of 0.010% constitutes a bare minimum risk of DAI because endoscope-related infections are underreported. Apart from DAI risk, a patient is also at risk of becoming colonized with a microorganism through contaminated endoscopes but without developing symptoms of clinical infection. These data call for consorted action of medical practitioners, industry, and government agencies to minimize and ultimately eliminate the risk of exogenous endoscope-associated infections and contamination. As a first step, the FDA recently recommended that healthcare facilities and manufacturers begin transitioning to duodenoscopes with disposable components.3Funding: NoneDisclosures: None

Abstract:
Abstract Introduction The use of endoscope is rapidly increasing in otological and neuro-otological surgery in the last 2 decades. Middle ear surgeries, including tympanoplasty, have increasingly utilized endoscopes as an adjunct to or as a replacement for the operative microscope. Superior visualization and transcanal access to diseases normally managed with a transmastoid approach are touted as advantages with the endoscope. Objectives The present study aimed to compare the outcomes of endoscopic and microscopic cartilage tympanoplasty (Type I) Methods This was a retrospective comparative study of 70 patients (25 males and 45 females) who underwent type I tympanoplasty between March 2015 and April 2016. The subjects were classified into 2 groups: endoscopic tympanoplasty (ET, n = 35), and microscopic tympanoplasty (MT, n = 35). Tragal cartilage was used as a graft and technique used was cartilage shield tympanoplasty in both groups. Demographic data, perforation size of the tympanic membrane at the preoperative state, operation time, hearing outcome, and graft success rate were evaluated. Results The epidemiological profiles, the preoperative hearing status, and the perforation size were similar in both groups. The mean operation time of the MT group (52.63 ± 8.68 minutes) was longer than that of the ET group (48.20 ± 10.37 minutes), but the difference was not statistically significant. The graft success rates 12 weeks postoperatively were 91.42% both in the ET and MT groups, that is, 32/35; and these values were not statistically significantly different. There was a statistically significant improvement in hearing within the groups, both pre- and postoperatively, but there was no difference between the groups. Conclusion Endoscopic tympanoplasty is a minimally invasive surgery with similar graft success rate, comparable hearing outcomes and shorter operative time period as compared to microscopic use.

Abstract:
Background: Minimally invasive surgery has recently been developed along with endoscopic techniques. Endoscopic Ear Surgery is becoming popular with its anatomic and physiologic concepts. Tympanoplasty is one of the commonest operations performed for the middle ear. While using the endoscope we can place the graft accurately while avoiding unnecessary post or endaural incision and soft tissue dissections which are mandatory during tympanoplasty using a microscope. Our study was aimed to compare the outcomes of endoscopic and microscopic tympanoplasty in terms of graft uptake, hearing outcome and postoperative pain. Methods: This is a retrospective comparative study of 63 patients who underwent type 1 tympanoplasty at Holy Family Hospital ENT Department from March 2017 to March 2020. The subjects were classified into 2 groups; Endoscopic tympanoplasty (ET, n=30), Microscopic Tympanoplasty (MT, n=33). Type 1 Tympanoplasty, was the procedure done on patients of both the groups. Demographic data, perforation size of the tympanic membrane at preoperative state, pure tone audiometric results preoperatively and 3 months postoperatively, operation time, sequential postoperative pain scale (NRS-11), and graft success rate were evaluated. Results : The perforation size of the tympanic membrane in the Endoscopic group and the microscopic group was nearly the same (p=.877). Pre and post-operative air-bone gaps including air and bone conduction thresholds were not significantly different between the two groups. The graft success rate in the endoscopic and Microscopic group was 93.3% and 63.3% respectively; the values were significantly different(p=0.0046). Immediate and 6 hours postoperative pain was similar in both the groups, however pain on ist postoperative day was significantly lower in the endoscopic group. Conclusion: We can do minimal invasive tympanoplasty with the help of endoscopes with better graft success rate, less preoperative time, and less postoperative pain.

Abstract:
Smaller endoscopes and catheters have been developed that permit direct visualization of the bile and pancreatic ducts (cholangioscopy and pancreatoscopy, respectively). These endoscopes and catheters are passed through the working channel of a standard therapeutic duodenoscope during endoscopic retrograde cholangiopancreatography (ERCP). The SpyGlass Direct Visualization System (Boston Scientific Corp, Natick, MA, USA) is currently the most widely used and studied device. Cholangioscopy with intraductal lithotripsy has become an established modality in the treatment of difficult biliary lithiasis. When used in the evaluation of indeterminate biliary strictures by experienced endoscopists in recognizing intraductal pathology, it increases the diagnostic yield of tissue sampling. Pancreatoscopy is complementary to other imaging modalities in the evaluation of intraductal papillary mucinous neoplasms of the pancreas and is emerging as a sole or adjunctive therapy to extracorporeal shock wave lithotripsy for the treatment of main pancreatic duct stones. It remains investigational in the diagnosis of pancreatic adenocarcinoma. Complications specific to the performance of cholangiopancreatoscopy include cholangitis, which is related to intraductal fluid irrigation.Abbreviations: EHL: Electrohydraulic lithotripsy; ERCP: Endoscopic retrograde cholangiopancreatography; ESWL: Extracorporeal lithotripsy by shock waves; ET: Endoscopic therapy; EUS: Endoscopic ultrasound; IPMN: intraductal papillary mucinous neoplasm; LL: Laser lithotripsy; MDCT: Multi-detector computed conventional tomography; MPD: Main pancreatic duct; MRCP: Magnetic resonance cholangiopancreatography; MRI: Magnetic resonance imaging; POCPS: Peroral cholangiopancreatoscopy; PSC: Primary sclerosing cholangitis

Abstract:
Background Data on external validation of models developed to distinguish Crohn’s disease (CD) from intestinal tuberculosis (ITB) are limited. This study aimed to validate and compare models using clinical, endoscopic, and/or pathology findings to differentiate CD from ITB. Methods Data from newly diagnosed ITB and CD patients were retrospectively collected from 5 centers located in Thailand or Hong Kong. The data was applied to Lee, et al., Makharia, et al., Jung, et al., and Limsrivilai, et al. model. Results Five hundred and thirty patients (383 CD, 147 ITB) with clinical and endoscopic data were included. The area under the receiver operating characteristic curve (AUROC) of Limsrivilai’s clinical-endoscopy (CE) model was 0.853, which was comparable to the value of 0.862 in Jung’s model (p = 0.52). Both models performed significantly better than Lee’s endoscopy model (AUROC: 0.713, p<0.01). Pathology was available for review in 199 patients (116 CD, 83 ITB). When 3 modalities were combined, Limsrivilai’s clinical-endoscopy-pathology (CEP) model performed significantly better (AUROC: 0.887) than Limsrivilai’s CE model (AUROC: 0.824, p = 0.01), Jung’s model (AUROC: 0.798, p = 0.005) and Makharia’s model (AUROC: 0.637, p<0.01). In 83 ITB patients, the rate of misdiagnosis with CD when used the proposed cutoff values in each original study was 9.6% for Limsrivilai’s CEP, 15.7% for Jung’s, and 66.3% for Makharia’s model. Conclusions Scoring systems with more parameters and diagnostic modalities performed better; however, application to clinical practice is still limited owing to high rate of misdiagnosis of ITB as CD. Models integrating more modalities such as imaging and serological tests are needed.

Abstract:
Abstract Background and study aims Ultrathin endoscopes are commonly used for surveillance esophagogastroduodenoscopy (EGD) to reduce discomfort associated with scope insertion. However, the flexibility of an ultrathin endoscope is a trade-off between reducing discomfort and lengthening examination time. Patients and methods The EG17-J10 (EG17) is a novel ultrathin endoscope characterized by its tapering body stiffness; however, the flexibility of its tip is comparable to that of the traditional ultrathin endoscope EG16-K10 (EG16). We compared EGD examination time between EG17 and EG16. A total of 319 examinees who underwent EGD from November 2019 to January 2020 at the Chiba-Nishi General Hospital were enrolled. Six examinees were excluded due to past history of surgical resection of the upper gastrointestinal tract or too much food residues; 313 examinees (EG17, 209; EG16,104) were retrospectively analyzed. The examination time was divided into three periods: esophageal insertion time (ET), gastroduodenal insertion time (GDT), and surveillance time of the stomach (ST). The total amount of ET, GDT, and ST was defined as total examination time (TT). Results TT of EGD using EG17 was significantly shorter compared to EGD using EG16 (222.7 ± 68.9 vs. 245.7 ± 78.5 seconds) (P = 0.004). Among the three periods of examination time, ET (66.7 ± 24.1 vs. 76.0 ± 24.1 seconds) (P = 0.001) and GDT (47.9 ± 17.4 vs. 55.2 ± 35.2 seconds) (P = 0.007) of EGD using EG17 were significantly shorter compared to EGD using EG16, except for ST (108.1 ± 51.5.1 vs. 114.5 ± 50.1 seconds) (P = 0.148). Conclusion An ultrathin endoscope with tapering body stiffness can shorten EGD examination time, mainly due to the shortening of insertion time.

Abstract:
OBJECTIVES: It is sometimes impossible to obtain an adequate laryngeal view during rigid endoscopic laryngoscopy. This may be due to a high tongue base. Our study seeks to determine a correlation between tongue base level and the adequacy of laryngeal view obtained with a 70-degree rigid endoscope. STUDY DESIGN AND SETTING: Over a period of 4 months, patients from a voice clinic were gathered and categorized into class I to III according to Mallampati et al (1985). Rigid laryngo-videostroboscopy was conducted to assess the larynx and the adequacy of the view was recorded. RESULTS: 74 patients were recruited. The number of adequate views were: class I = 18/20 (90%); class II = 20/33 (60.6%); class III = 7/21 (33.3%). χ2 analysis demonstrated significance trend in all 3 classes. CONCLUSION: The level of the tongue base correlated well with the adequacy of laryngeal view obtained from a 70-degree rigid endoscope. This can be used to predict the success of obtaining adequate views during rigid laryngoscopy.

Abstract: Introduction: The usefulness of nasal packing after endoscopic sinus surgery is still debated in the literature. Aim: Our aim was to evaluate the effects of a new chitosan-based nasal dressing in animal model. Methods: Standard mucosal damage was caused in both nostrils during endoscope-assisted procedure in ten rabbits. Chitosan nasal packing was inserted in a randomly selected nasal fossa of each animal, while the other side was left unpacked. Symptoms were evaluated during nasal endoscopy on the 12th postoperative week. The degree of mucosal oedema, crusting, adhesions and the nasal discharge were observed according to the modification of the grading system of Berlucchi et al. The higher scores indicated the worse complaints. Results: Assessing the adhesion formation, 1 point was given (mean: 0.1; standard deviation [SD]: 0.32) for the unpacked side, while in the tamponated side no adhesion formation was observed. The total score of crusting in the non-packed side was lower with 1 point (total score: 9, mean: 0.90; SD: 0.74) than in the chitosan side (total score: 10, mean 1.00; SD: 0.82). Discharge or mucosal oedema were not observed during the follow-up period. The mean rate, measured with electronmicroscopy, was 22.06% (SD: 0.25) in the chitosan side, while in the non-packed side it was 36.11% (SD: 0.48). The differences did not show any significance (p = 0.806). Conclusion: During the examinations, none of the animals suffered complications. The symptoms of the packed and the non-packed nasal cavities did not differ significantly on the basis of our examinations. Orv Hetil. 2018; 159(47): 1981–1987.

Abstract:
The pathological entities commonly associated with lumbosacral pain are the intervertebral discs, facet joints or surrounding muscle. However, in the absence of diagnostic confirmation of the aforementioned structures, the diagnosis may become confusing and intractable. Sacroiliac fascial lipocele (SFL), namely, pannicular hernia, could be a neglected cause. First reported by Ficarra et al in 1952, it was highlighted by the formation of lipocele in the sacroiliac fascia. Mostly, it could be spontaneously eliminated under conservative therapy. However, for intractable pain, surgical intervention may be the only choice. We will first present a typical case of SFL which was treated by percutaneous endoscopic surgery. Ultimately, a satisfactory outcome was achieved and maintained at 12 months follow-up. It is important to distinguish SFL some cases with lumbosacral back pain. Detailed physical examination, superficial ultrasonography and diagnostic nerve block are extremely valuable for acquiring a precise diagnosis. Overall, when considering the clinical outcome of such cases and the foregoing benefits, percutaneous endoscopic treatment could be an efficacious alternative treatment for SFL-related lumboscral back pain.

Abstract:
Background: Multiple outbreaks multidrug-resistant organisms (MDROs) have been associated with flexible endoscopes resulting in unacceptable patient mortality and morbidity. Evidence highlights the importance of effective cleaning to achieve effective high-level disinfection (HLD). This study presents an analysis of >700,000 measurements of adenosine-triphosphate (ATP) contamination levels found in flexible endoscopes after manual cleaning. Method: This 2018–2019 study consists of 702,768 measurements of ATP levels found in the suction/biopsy channel of instruments used on patients after manual cleaning: gastroscopes (267,533 measurements from 223 sites), duodenoscopes (123,697 measurements from 161 sites), colonoscopes (252,249 measurements from 229 sites), and bronchoscopes (59,289 measurements from 107 sites). Sites were located across the United States and employed protocols that included routine cleaning verification performed by the reprocessing technicians using a handheld luminometer and the associated ATP water test (3M Clean-Trace). Results: Figure 1 shows a boxplot analysis of the ATP levels by endoscope type. Upper gastrointestinal (GI) endoscopes (gastroscopes and duodenoscopes) show a significantly (P < .005) greater level of ATP contamination after manual cleaning. The pairwise mean differences are all significant (P < .005) except for colonoscopes when compared to bronchoscopes (P = .203). Also shown on Fig. 1 is a literature supported adequate cleanliness value of 200 RLUs [=2.3log(RLUs)] (MJ Alfa et al.; Am J Infec Control 2013;41:245–253 and ANSI/AAMI ST91; 2015). A 95% confidence interval analysis performed against this literature value (Table 1) showed that a high number of gastroscopes (12%) and duodenoscopes (10%) are not adequately clean. Figure 2 shows a box-plot analysis of the data set by endoscope type and by site. There is significant (P < .005) site-to-site variability for all endoscope types as demonstrated by variation in mean values, box size, and many outliers. Conclusions: This study highlights the importance of using a quantitative cleaning verification method to better understand process capability and to provide more robust quality assurance for manual cleaning. Significant differences were detected in the level of cleanliness between upper GI scopes and lower GI scopes and bronchoscopes. When compared to a literature-supported level for adequate cleanliness, upper GI scopes exhibited failure rates in excess of 10%. Furthermore, significant site-to-site variability occurred, and many outliers fell well beyond the normal process envelope, representing significant cleaning lapses. Root causes to these concerning findings could range from inadequate execution of the cleaning protocol, to device design, to age and existing damage that could prevent achieving adequate cleaning and possibly impair the effectiveness of HLD.Funding: NoneDisclosures: Marco Bommarito, 3M (salary)

Abstract:
ABSTRACT The study has been conducted over a period of 4 years, on a total number of 133 dogs, all of those expressing gastrointestinal disorders. Ultrasound and endoscopic examinations were performed in all dogs in order to assess any significant correlations between ultrasonographic and endoscopic findings. The results confirm a significant correlation between the presence of diarrhoea and increased thickness of the large bowel wall, with P<0.5. Another extremely significant correlation we observed is the one between increased thickness of large bowel wall and loss of layering at this level, with P<0.5. Upper GI endoscopy revealed that dilated lacteals in the duodenum are significantly associated with the presence of diarrhoea, P<0.5 and, more importantly, there is a very significant correlation between dilated lacteals and the presence of striations (P<0.5), which confirms previous studies (Sutherland-Smith et al., 2007) that say the striated aspect of the intestinal mucosa is due to dilated lacteals.

Abstract:
BACKGROUND: Percutaneous endoscopic gastrostomy performed as proposed by Gauderer et al. in 1980, has been used quite frequently in patients with head and neck tumors. Some authors believe that this so-called pull technique would be associated to the risk of a tumor implantation in the wound as well as high levels of peristomal wound infection. Although some alternative techniques provide better results, doubts about their technical applicability in daily practice still persists. AIM: To assess the feasibility, safety and morbidity of percutaneous endoscopic gastrostomy performed through a well-defined and standardized technique in patients with nonresectable or advanced head and neck cancer. METHODS: A consecutive series of patients who had either nonresectable or advanced tumors and were unable to be fed orally were submitted to an oncologic-hospital-based tertiary-referral endoscopy practice. Tubes were implanted through an introducer technique comprised of two main stages. The first consisted of the application of two stitches aiming to fixate the anterior gastric wall to the abdominal wall, and the second being the inserting of the gastrostomy tube. RESULTS: Between February 2003 and May 2004, 129 percutaneous endoscopic gastrostomies were performed. This study included 60 patients. They were all able to receive food on the same day. Operative morbidity was observed in six patients (10%) and one procedure-related mortality was also observed (1.6%). CONCLUSION: Percutaneous endoscopic gastrostomy is both feasible and safe, associated to low morbidity, and to acceptable mortality rates.

Abstract:
Background: Endoscopic thyroidectomy (ET) is now an accepted treatment for benign and certain malignant thyroid diseases. It is clearly evident that ET is mainly done to lessen pain and avoid scar in the neck. Any procedure which involves using the endoscope to remove thyroid is often collectively called “endoscopic thyroidectomy.” In this article, we would like to share our institute experience in doing ET.Methods: We did ET on 85 patients from November 2014 to October 2019 mostly by the three-port technique. Preoperative assessment was done and surgery was done on those who met the inclusion criteria. All the cases were done with the insufflation of carbon dioxide gas. Per operative events were noticed and all the patients were followed up at least for 3 to 6 months postoperatively.Results: The mean age of the patient is 38 years and the majority are females (92.94%). Out of 85 cases, one case was converted to an open method (1.18%). The average operative time to complete the procedure was 67 minutes. Most of the cases were discharged on 2nd to 3rd postoperative days. Few patients had complications like hematoma/seroma formation, paresthesia over the infraclavicular region, skin thermal injury, vascular injury, and tracheal injury.Conclusion: ET gives excellent cosmesis and lessens the post-operative pain and thus lesser hospital stay even though the extent of the dissection is more than the conventional method. It has variable complications according to the techniques adopted and the size/volume of the surgically excised thyroid gland.

Abstract:
Abstract Background Therapeutic options in IBD are rapidly growing, causing new challenges including choice of first line therapy. Both adalimumab (ADM) and vedolizumab (VDZ) are effective at inducing and maintaining endoscopic remission in moderate-to-severe IBD. The VARSITY trial (Sands et al NEJM 2019) showed superiority of VDZ over ADM in achieving clinical remission and endoscopic improvement at W52 in UC patients. Our aim was to explore if these results withstand in a real world setting of UC patients, and if they are also valid in CD. Methods This retrospective cohort study included adult, biological-naive IBD patients starting ADM or VDZ between 2015-2019 in our referral IBD centre. Patients had moderate-to-severe disease (endoscopic Mayo sub score ≥ 2 for UC, presence of ulcerations for CD) prior to start of therapy. For UC, we assessed endoscopic remission (endoscopic Mayo sub score 0) and improvement (endoscopic Mayo sub score ≤ 1) at W52. For CD, we assessed endoscopic remission (absence of ulcerations) and improvement (markedly better endoscopy despite still presence of ulcerations) at weeks 26-52. Missing values were imputed as nonresponses for binary outcomes, and last-observation carried-forward was used for continuous outcomes. Results A total of 109 UC and 86 CD patients were included (Table 1). Endoscopic remission at W52 was significantly better for VDZ than ADM in UC (35% vs 15%, p=0.03), and also endoscopic improvement was numerically, yet not significantly, better for VDZ than ADM (56% vs 37%, p=0.08). At baseline, 23 UC patients (50%) in the ADM group and 40 (63%) in the VDZ group were on steroids. By W52, 83% and 78% (p=0.75) of UC patients respectively could discontinue steroids and steroid-free endoscopic remission was not different between groups (ADM: 22% vs VDZ: 23%, p=1.00). For CD patients, similar endoscopic remission (60% vs 48%, p=0.37) and improvement (77% vs 79%, p=1.00) rates at weeks 26-52 were seen between ADM and VDZ. Twenty-five (47%) CD patients in the ADM and 16 (48%) in the VDZ group were on steroids at baseline, and 88% of them in both groups could successfully stop steroids by W52. Again, no difference in steroid-free endoscopic remission was seen between ADM (56%) and VDZ (31%) treated CD patients (p=0.20). At the end of follow-up [81 (27-157) weeks], the rates of treatment persistence were significantly different between ADM and VDZ treatment groups in UC patients, though not in CD patients (Figure 1). Conclusion In a real-world cohort of bio-naive UC patients, VDZ was superior to ADM in achieving endoscopic remission at W52, while in bio-naive CD patients VDZ and ADM resulted in similar endoscopic outcomes.

Abstract:
42 Background: Patients after esophagectomy for esophageal squamous cell carcinoma (ESCC) were reported to have a remarkably high risk of subsequent cancer of head and neck cancer (Matsubara, et al. J Clin Oncol 2003). The outcome was reported to be significantly less favorable as a result of difficulty in early detection. However, magnifying endoscopy combined with narrow band imaging (NBI) system recently allowed early detection of head and neck cancer. This study was to assess the risk of subsequent malignancies after esophagectomy for ESCC for the establishment of an adequate follow-up program. Methods: Eighty patients with ESCC who had undergone radical esophagectomy at the Kawasaki Municipal Hospital from 2000 to 2006 were eligible for this study. Among the eighty patients, we analyzed 41 cases who survived more than 5 years after esophagectomy. Results: Median survival of the 41 patients was 7.1 years. Two patients who developed squamous cell carcinoma in the lung within 5 years after esophagectomy were not included in the group of subsequent second malignancies, because it was difficult to distinguish primary tumors from metastatic tumors. Second malignancies were found in 7 (17.1%) of 41 patients subjected to curative esophagectomy. Subsequent malignancies were most frequently found in the head and neck region (n = 4; 57.1%), followed by the residual esophagus (n = 1; 14.3%), colon (n = 1; 14.3%), and breast (n = 1; 14.3%). The subsequent cancers in head and neck, and residual esophagus were detected from 1 to 9 years after esophagectomy in an early stage with magnifying endoscopy combined with NBI system. They were curatively resected by endoscopic laryngo-pharyngeal surgery (ELPS) and endoscopic submucosal dissection (ESD). The subsequent cancers in colon and breast were also curatively resected by operation. Conclusions: Patients after esophagectomy for ESCC had a high risk of subsequent cancer of head and neck cancer. Minute postoperative surveillance with magnifying endoscopy combined with NBI system is strongly recommended even more than 5 years after esophagectomy. Early detection of second malignancies allowed less invasive treatment such as ELPS and ESD with favorable outcome.

Abstract:
En cas d'hématémèse, une endoscopie en urgence doit être effectuée aussi rapidement que possible. En cas de mise en évidence d'un ulcère, un traitement par endoscopie doit être effectué en présence d'un saignement actif ou de vaisseaux visibles. Il n'y a pas de différence significative entre les différentes formes d'hémostase. La méthode de référence en cas de saignement de varices oesophagiennes est l'hémostase endoscopique par ligature ou sclérose. Pour la prévention de récidive, la ligature s'est imposée comme la méthode de choix en raison de taux de complications nettement plus bas. Il est recommandé de compléter le traitement par un bêtabloquant, particulièrement chez les patients qui présentent une gastropathie hypertensive portale. En prophylaxie primaire, l'indication à un traitement combinant un bêtabloquant et un dérivé nitré est posée chez les patients avec de grosses varices de coloration rouge et chez ceux présentant une fonction hépatique perturbée.

Abstract:
The intrinsic fluorescence achieved without dyes (autofluorescence) of bladder tissue, benign mucosa and the various stages of transitional cell carcinoma (TCC), is being characterized. D'Hallewin, et al., and Koenig, et al., are testing autofluorescence spectroscopy for detecting bladder carcinoma using an optical fiber probe inserted down the auxiliary channel of an endoscope. These studies do not include fluorescent microscopy to directly examine the fluorescing structures (fluorophores) within the tissue. Therefore, frozen unstained sections are being imaged on a fluorescence microscope to identify and reveal the morphology and location of the fluorophores. Tissue biopsies taken at endoscopy are immediately frozen in liquid nitrogen. Later, the tissue is cut into 5 μm sections. Serial sections are alternately imaged frozen on the fluorescence microscope or stained with hematoxylin-and-eosin (H&E). The H&E stained slides are reviewed by a pathologist.A 75-W xenon arc lamp fitted with a 380-nm narrow-band interference filter is coupled to microscope slides on the stage of an Olympus MT-2 inverted microscope.

La prise en charge des tumeurs précoces du rectum (adénomes et adénocarcinomes classés usT1N0) est importante à connaître du fait de leur fréquence accrue. Le risque d’envahissement ganglionnaire étant faible (0 à 8%), l’exérèse locale est la résection de référence pour les tumeurs classées Tis et T1sm1, et une option séduisante pour les tumeurs T1sm2. La résection chirurgicale transanale par TEM (transanal endoscopic microsurgery) et la dissection sous-muqueuse (ESD) endoscopique sont les 2 techniques de référence pour les adénocarcinomes précoces. Avec des taux d’exérèse complète respectifs de 88,5% et 84%, la TEM et l’ESD sont recommandées indifféremment dans cette indication par l’Association Européenne de Chirurgie Endoscopique (EAES). Seules deux études monocentriques, rétrospectives et de faibles effectifs ont comparé ces deux techniques sans mettre en évidence de différence. Une étude nationale prospective est actuellement en cours.

Abstract:
Les traitements interventionnels ont pris toujours plus d'importance ces dernières années particulièrement en endoscopie. Il existe un grand nombre d'approches interventionnelles tant à visée curative que palliative qui doivent être considérées comme le « golden standard » comparées aux options chirurgicales. La coagulation endoscopique en présence d'ulcère ou de varices oesophagiennes permet de très bons résultats et est aujourd'hui la méthode de choix. Des opérations en urgence ne sont que rarement nécessaires. Les sténoses bénignes de l'oesophage appartiennent au domaine du traitement endoscopique: la dilatation par ballonnet ou par bougie donne des résultats similaires. En cas d'achalasie, l'âge et la co-morbidité du patient jouent un rôle important dans les considérations de diagnostics différentiels. Chez les patients jeunes, il faut éviter les injections endoscopiques de toxines botuliniques puisque l'on ne peut pas s'attendre à des résultats satisfaisants au long cours et qu'une opération est ainsi rendue plus difficile à un stade ultérieur. La polypectomie endoscopique ainsi que la mucosectomie ont une grande importance en raison de la haute fréquence du carcinome colo-rectal puisqu'une vraie prévention est possible et qu'il est possible de guérir les carcinomes précoces en tenant compte des facteurs de risque.

Abstract:
Abstract Background and study aims Endoscopic submucosal dissection (ESD) is a technically advanced procedure for colorectal tumors. Hayashi et al. invented the “pocket-creation method (PCM),” and reported that Is-type lesions with fibrosis could be efficaciously and safely resected. However, only case studies have been published, and there are no previous reports on the usefulness of PCM in colorectal ESD for all lesions, as compared with the conventional method. This study aimed to evaluate the effectiveness and safety of PCM in colorectal ESD. Patients and methods Ninety-six colorectal tumors were treated: 47 using the PCM and the other 49, considered the control group, using the conventional method. Therapeutic effectiveness and safety were retrospectively assessed. Results The comparison between the PCM and control groups revealed higher rates of en bloc resection (100 % vs. 88 %, P = 0.015) and curative endoscopic resection (100 % vs. 84 %, P = 0.0030) with PCM. There was no significant difference in perforation as an adverse event (AE) between the two groups, though perforation was observed in only 6 % of the control group and none of the PCM group. Compared with the control group, the PCM group had lower incidences of perforation and post-ESD coagulation syndrome, and both AEs were associated with excessive thermal denaturation of the muscle layer (2 % vs. 16 %, P = 0.018). Conclusions This study demonstrated the effectiveness and safety of ESD with PCM for colorectal tumors. Although there is a possible learning curve, PCM enables the endoscopist to safely perform ESD in most cases without encountering the difficulties associated with conventional ESD.

Introduction: We report our experience with endoscopic ablationof Hunner’s lesions in women with interstitial cystitis (IC).Methods: A chart review was performed on 14 patients with ICsymptoms who were identified to have bladder lesions and underwentendoscopic ablation. A Hunner’s lesion was identified asan area of erythema that reproduced the patients’ pain when touchedby the cystoscope. Pathology reports were reviewed and improvementin pain was used as the main outcome measure.Results: Of the 14 patients, 12 had more than 50% symptomaticimprovement and 8 patients reported 100% improvement. Meanimprovement was 76%. In all patients who improved, the biopsyspecimen showed inflammatory cystitis, often with epithelialdenudation. Four patients had symptomatic recurrence, but allhad improvement after repeat ablation.Conclusion: Endoscopic ablation of Hunner’s lesions improves symptomsin IC patients. Recurrence of symptoms should prompt repeatcystoscopy to identify recurrent lesions, as repeat ablation offerssymptomatic improvement.Introduction : L’article fait état de notre expérience concernantl’ablation endoscopique d’ulcères de Hunner chez des femmesatteintes de cystite interstitielle (CI).Méthodologie : On a mené un examen des dossiers de 14 patientesprésentant des symptômes de CI chez qui des lésions vésicalesavaient été observées et traitées par ablation endoscopique. Unulcère de Hunner était défini comme une zone d’érythème reproduisantla douleur décrite par la patiente lorsque cette zone étaittouchée à l’aide du cystoscope. Les rapports de pathologie ontété examinés et la réduction de la douleur a été utilisée commeprincipal critère d’évaluation.Résultats : Sur les 14 patientes, 12 ont présenté une réduction supérieureà 50 % des symptômes et 8 ont signalé une réduction de 100 %. Letaux moyen de réduction était de 76 %. Chez toutes les patientesayant signalé une réduction des symptômes, l’échantillon de tissuprélevé par biopsie montrait la présence de cystite inflammatoire,souvent accompagnée de dénudation épithéliale. Quatre patientesont signalé une réapparition des symptômes, mais une nouvelle ablationa permis de réduire encore une fois les symptômes.Conclusion : L’ablation endoscopique des ulcères de Hunner entraîneune réduction des symptômes en présence de CI. La réapparitiondes symptômes devrait être prise en charge par une nouvelle cystoscopieafin de repérer les nouvelles lésions; une nouvelle ablationpermet de soulager les symptômes.

Abstract:
Many of the prostatic cysts are asymptomatic and only 5% are symptomatic (Hamper et al., 1990; Higashi et al., 1990). These symptoms include pelvic pain, hematospermia, infertility, voiding dysfunction, prostatitis-like syndrome, and painful ejaculation. Treatment of prostatic cysts includes TRUSG guided drainage, endoscopic transurethral resection, and in some cases even open surgery. In the literature, endoscopic interventions use marsupialization of the midline prostatic cyst with transurethral resection (TUR) or transurethral incision with endoscopic urethrotomy (Dik et al., 1996; Terris, 1995). Holmium: YAG laser was employed for the marsupialization of the cyst wall in midline prostatic cyst treatment for the first time in the present study. Symptoms, treatment, and follow-up are presented in this paper.

Abstract:
Objective: Catheter ablation has been a common procedure used for the management of atrial fibrillation (AF). Atrioesophagel fistula (AEF) is one of the most feared complications of AF ablation. Although it is a rare complication, severe esophageal thermal injury must be avoided. It is important to describe a safe method of preventing esophageal injuries without increasing AF recurrence. Methods: A retrospective cohort study of consecutive patients who underwent radiofrequency AF catheter ablation during 1 year-period wa conducted. One hundred and four patients were enrolled divided in two groups: one with a maximum recorded esophageal temperature (ET) < 38 °C and other with a maximum recorded ET ≥ 38 °C. The primary endpoint was detection of endoscopic esophageal lesions after AF ablation and the secondary endpoint was AF recurrence according to the maximum ET reached during the procedure. Results: The maximum ET was on average 37.3 ± 1.0 °C. Only 4 (3.8%) patients had esophageal lesion diagnosed by upper gastrointestinal endoscopy. There were no cases of esophageal perforation. The AF recurrence rate was 9.6% during the follow-up (10 patients, 3 from the ET max < 38 °C group and 7 from the ET max ≥ 38 °C group; p = 0.181). The maximum ET was not associated with AF recurrence after catheter ablation (OR = 1.65, 95% CI = 0.84-3.24, p = 0.14). Conclusions: A low incidence of esophageal injury after AF ablation with the use of a specific esophageal protection protocol was found. There was no esophageal perforation. The AF recurrence rate was similar to that described in the literature.

Abstract:
Introduction Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment. Objective To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases. Methods Ours was a descriptive study performed with 106 patients attending the Ear, Nose and Throat (ENT) Outpatient Department of a tertiary care center in South India with features suggestive of middle ear disease. All patients underwent impedance audiometry and dynamic slow motion nasal video endoscopy, and were graded based on the severity of the ET pathology. Results A total of 47 out of 97 patients with abnormal endoscopy findings also had abnormal impedance audiometry. The correlation was greater among the patients with higher grades of ET dysfunction. The endoscopy findings of 106 cases, when correlated with middle ear manometry, revealed that 56 cases showed complete agreement, and 50 cases showed disagreement. The nasal endoscopy results, when correlated with middle ear manometry studies by using McNemar's chi-squared (χ2) test, showed a significant association between the 2 tests (p = 0.017). Conclusion There is a significant alteration in middle ear pressure as the severity of the ET tube dysfunction increases. Impedance audiometry and nasal endoscopy provide a better measure of ET function.
