Abstract:
✓ Decreased memory and learning efficiency may follow left temporal lobectomy. Debate exists as to whether the acquired deficit is related to the size of the surgical resection. This study addresses this question by comparing changes in cognitive performance to the extent of resection of both mesial temporal structures and lateral cortex. The authors retrospectively reviewed 47 right-handed patients who underwent left temporal lobectomy for medically intractable seizures. To examine the effects of the extent of mesial resection, the patients were divided into two groups: those with resection at the anterior 1 to 2 cm of mesial structures versus those with resection greater than 2 cm. To examine the effects of the extent of lateral cortical resection, patients were again divided into two groups: those with lateral cortex resections of 4 cm or less versus those with resections greater than 4 cm. Statistical analyses showed no difference in cognitive outcome between the groups defined by the extent of mesial resection. Likewise, no difference in cognitive outcome was seen between the groups defined by the extent of lateral cortical resection. Associated data analyses did, however, reveal a negative correlation of cognitive change with patient age at seizure onset. These results showed that the neurocognitive consequences of extended mesial resections were similar to those of limited mesial resections, and that the neurocognitive consequences of extended lateral cortical resections were similar to those of limited lateral cortical resections. The risk of cognitive impairment depends more on age at seizure onset than on the extent of mesial or lateral resection.

Abstract:
Abstract Standard resection for patients with thymoma is resection of thymoma with total thymectomy (TTx) via median sternotomy. Hence, limited resection for thymoma means a lesser extent of resection of normal thymus compared with a standard procedure, i.e. resection of thymoma with partial thymectomy (PTx). In contrast, minimally invasive resection has been defined as resection of thymoma with TTx via a less-invasive approach. However, to date, few studies have precisely evaluated the differences in surgical and oncological outcomes among these three procedures. This report summarizes the differences among these three procedures with a review of studies (January 2000 to December 2020) focusing on the difference in surgical and oncological outcomes and presents current issues in the surgical management of thymoma. In this report, 16 studies were identified; 5 compared standard resection to limited resection, 9 compared standard resection to minimally invasive resection and 2 compared limited resection to minimally invasive resection. Most studies reported that the surgical and oncological outcomes of limited resection or minimally invasive resection were similar to those of standard resection in patients with early-stage thymoma. However, they did not include a sufficient follow-up period. Both limited resection and minimally invasive resection for early-stage thymoma might be reasonable treatment options. However, they are still promising modes of resection. Further studies with a long follow-up period are needed.

Abstract:
The surgical management of duodenal pathology is challenging because of its retroperitoneal position and shared blood supply with the pancreas. We present three types of limited resection of the duodenum for the removal of superficial or small nonampullary duodenal (NADL) lesions, and also a review of the English literature regarding management, such as endoscopic resection and limited duodenal resection. Ten cases underwent limited resections of the duodenum for superficial or small NADL lesions from 2011 to 2015. Pancreas-preserving segmental duodenectomy was performed in three cases, local full-thickness resection was performed in three and transduodenal submucosal dissection was performed in four. One patient experienced pancreatic fistula as a postoperative complication. Postoperative pathological diagnosis were adenoma (n = 2), mucosal adenocarcinomas (n = 5), and neuroendocrine tumor (n = 3). Surgical margin was negative in all cases, and no patient has experienced postoperative recurrence or metastasis. Limited resections of the duodenum were feasible and safe procedures for patients with superficial or small NADL lesions. Laparoscopic surgery may be considered in treatment for these tumors. However, the optimal surgical management for superficial or small nonampullary duodenal lesions remains controversial.

Abstract:
Endoscopic full-thickness resection (FTR) is a novel technique for endoscopic treatment of colorectal neoplastic lesions that are not suitable for standard endoscopic resection. Published evidence on FTR suggests high technical success rate, high proportion of R0 resections and low risk of serious complications. According to limited data, FTR appears to be a recommendable alternative to the technically challenging and time consuming endoscopic submucosal dissection (ESD) in the treatment of carcinomas with superficial submucosal invasion and local residual neoplasia, specifically outside the rectum. The main limitations of FTR are the limited extent of resection and occasional residual neoplasia after resection. Further research including prospective and randomized comparison to other resection techniques is needed for a correct inclusion of FTR in the treatment algorithm of colorectal neoplasia.

Abstract:
Les cancers du foie sont la seconde cause de mort par cancer avec plus de 745,000 morts en 2012. Si l'on inclut les cas de cirrhose du foie, le nombre total de morts par an dans le monde atteint presque 2 million. Le meilleur traitement actuel pour ces patients est l'ablation chirurgicale de ces tumeurs. Pour les localiser et planifier l'opération, les chirurgiens se basent sur des images médicales pré-opératoires (obtenues par tomodensitométrie ou imagerie à résonance magnétique). Cependant, durant l'intervention, ces tumeurs, ainsi que le réseau vasculaire du foie, sont difficiles à localiser pour le chirurgien. Cela peut conduire à une résection incomplète des tumeurs où à la lésion accidentelle de vaisseaux sanguins. Le but de ce travail de thèse est de proposer aux chirurgiens une vue du foie et de ses structures interne en réalité augmentée durant l'opération pour les aider à réséquer les tumeurs de manière optimale en limitant les risques pour le patient. Pour cela, une méthode de recalage élastique des données pré-opératoires sur la vue intra-opératoire a été développée. Cette méthode, qui utilise un modèle biomécanique et certains repères anatomiques présents sur le foie, a été conçue pour limiter son impact sur la routine clinique et permet d'atteindre une erreur de recalage inférieure aux marges chirurgicales même en cas de déformation importante du foie entre son état pré-opératoire et intra-opératoire. Cet algorithme de recalage a été intégré à un logiciel, sofaOR, pour permettre les premiers essais cliniques
Liver cancer is the 2nd most common cause of cancer death worldwide, with more than 745,000 deaths from liver cancer in 2012. When including deaths from liver cirrhosis, the toll reaches nearly 2 million people worldwide. Today, surgical tumors ablation remains the best treatment for liver cancer. To localize the hepatic tumors and to define the resection planes, clinicians rely on pre-operative medical images (obtained with computed tomography scanner or magnetic resonance imaging). However, the liver lesions and vascular system are difficult to localize during surgery. This may lead to incomplete tumor resection or haemorrhage. The purpose of this thesis work is to provide surgeons with an augmented view of the liver and its internal structures during surgery to help them to optimally resect the tumors while limiting the risk of vascular lesion. Therefore, an elastic registration method to align the pre-operative and intra-operative data has been developed. This method, which uses a biomechanical model and anatomical landmarks, was designed to limit its impact on the clinical workflow and reaches a registration accuracy below the resection margin even when the liver is strongly deformed between its pre-operative and intra-operative state. This registration algorithm has been integrated into a software, sofaOR, to conduct the first clinical tests

Abstract:
Neuroblastoma is the most common extracranial solid tumor of childhood, and limited or complete surgical resection is performed in most cases. Anesthesia for these children can be challenging because of the size and location of the tumor, the secretion of vasoactive metabolites from the tumor, and because it involves major surgery in a potentially immunocompromised patient. Adequate preparation for these procedures can avoid intraoperative instability.

Abstract:
A significant percentage of patients with systemic cancer will develop brain metastasis at some point in the course of their disease. Brain metastases should be suspected if patients with known cancer histories present with new neurologic symptoms. Treatment for brain metastasis typically involves radiation. Patients with large, symptomatic and/or solitary brain metastases may benefit from surgical resection in addition to radiation. The role of systemic therapy for brain metastases remains somewhat limited, but newer treatment strategies such as immune therapy and molecular targeted agents may play a role in the future.

Abstract:
Despite advances in imaging techniques, many patients with renal cancer still present with locally advanced or metastatic disease. Surgical resection remains the main stay of treatment for locally advanced disease, but is technically challenging and survival remains limited. Progression free and overall survival following nephrectomy are dependent on many factors including pathological T-stage, lymph node status, and Fuhrman grade. Patients presenting with metastatic disease still have a poor prognosis and the use of multimodal therapy has yet to deliver dramatic improvements in outcomes, with just 15% of patients surviving in the long term. Understanding the potential but also the limitations of surgery is very important when the overall prognosis may be so limited in this challenging group of patients.

Abstract:
Cushing’s syndrome is a descriptive term of a syndrome secondary to elevated levels of steroids or cortisol, while Cushing’s disease is hypercortisolemia that results from an adrenocorticotropic (ACTH)-secreting pituitary adenoma. Patients will present with cushingoid features on physical examination and can be myopathic with proximal rather than distal muscle weakness. Diagnosis can be obtained by multiple avenues including but not limited to checking 24 hour urine cortisol, a dexamethasone suppression test, checking ACTH levels, a CRH (corticotrophin-releasing hormone) stimulation test, and inferior petrosal sinus sampling (IPSS). Once Cushing’s disease is confirmed, treatment is via transsphenoidal resection of the pituitary adenoma.

Abstract:
Minimally invasive techniques aim to improve upon traditional open surgeries by limiting the morbidity of the surgical approach. In doing so, soft tissue collateral injury is minimized, the midline is relatively spared, and the amount of osseous resection is reduced. Both open and minimal-access procedures are options for decompressing neural tissue, correcting spinal column malalignment, or stabilizing vertebral motion segments. Minimally invasive techniques reduce the necessary soft tissue retraction and surgical dissection with the goal of reducing postoperative pain and expediting recovery. However, the limited access afforded by these approaches can be challenging for complex and revision procedures, and the surgeon must be familiar with the specialized instrumentation and novel technologies. The decision to use minimally invasive techniques is multifactorial and is largely dependent on patient, surgeon, and hospital factors.

Abstract:
Electrocorticography (ECoG) is the method of recording electroencephalographic signals directly from surgically exposed cerebral cortex. It detects intraoperatively the cortical regions with substantial epileptiform interictal discharges. Direct cortical stimulation during ECoG provides a method of identifying language, motor, and sensory regions during a craniotomy. Both techniques—the identification of cortex with epileptic activity and cortex with important eloquent functional activity—help determine limits for surgical cortical resection. These are used most commonly during epilepsy and tumor surgery. Anesthetic agents can adversely affect the recording, and ECoG restricts the types of anesthesia that can be used. The amount of spiking from diffuse or remote cortical regions on ECoG can predict the success of postoperative seizure control.

Abstract:
Surface or scalp electroencephalography (EEG) has become an indispensable tool for the diagnosis, classification, and care of patients with epilepsy across the age spectrum. This chapter provides an overview of interictal and corresponding ictal scalp EEG patterns observed in adults with certain classical epilepsy syndromes. In patients with one or more new-onset seizures, the value of EEG testing begins with a close examination of the interictal record. The morphology, frequency, and topography of interictal epileptiform discharges (when present) are typically sufficient to broadly distinguish between the propensity to develop “generalized seizures” (those that rapidly engage a distributed epileptogenic network) or “focal seizures” (which have a stereotyped onset within a clearly lateralized focal region or network). Epileptiform discharges may also be seen in patients without epilepsy who are affected by certain acute (e.g., severe metabolic encephalopathies) or chronic neuropsychiatric syndromes (e.g., autism spectrum disorder). An examination of the ictal recording is of crucial importance in patients with medication-refractory focal onset seizures as it serves to guide patient selection and ancillary testing for the possibility of resective surgery for epilepsy. This chapter also highlights the limited anatomical sensitivity of EEG for seizures that lack an associated impairment in consciousness (“simple partial seizures”) or those that remain confined to mesial, deep or inferior cortical regions.

Abstract:
Bronchiectasis represents irreversible bronchial dilatation. It can be focal or diffuse, and usually results from chronic infection, proximal airway obstruction, or a congenital bronchial abnormality. Traction bronchiectasis refers to irregular bronchial dilatation in the setting of surrounding pulmonary fibrosis. Patients with cystic fibrosis have a progressively worsening clinical course, with recurrent pneumonias and chronic airway colonization. Even with lung transplantation and modern antibiotic therapies, average life expectancy of cystic fibrosis patients remains limited to young adulthood. Non-cystic fibrosis related bronchiectasis can cause chronic cough and recurrent lung infection. Pulmonary function testing often reveals evidence of obstruction. Treatment of patients with mild to moderate bronchiectasis involves supportive care with bronchodilators, antibiotics, and other medical therapy. Surgical resection is uncommon, and usually reserved for cases of significant bronchiectasis limited to a single region of the lungs (such as a particular lobe or segment).

Full text
Abstract:
Colonic volvulus is the third leading cause of large bowel obstruction. About 35% of these are located in the caecum. Though, relatively, a rare cause of obstruction, the incidence of caecal volvulus is steadily increasing at a rate of about 5% per year. Mortality due to caecal volvulus may be as high as 40% especially in the presence of gangrene and sepsis. Clinical presentation may be acute and fulminant or as a mobile caecum syndrome with intermittent abdominal pain. “Whirl,” “Coffee bean,” and “bird beak” signs seen on computed tomography are pathognomonic. Colectomy is the preferred treatment as it obviates any chance of recurrence. A conservative approach to colectomy such as limited ileocaecal resection and ileostomy formation in critically ill patients or in those with poor physiological reserve may be associated with better postoperative outcomes.

Abstract:
Aim: To evaluate the mortality and morbidity related to bowel resection in women with advanced ovarian carcinoma. Methods: Retrospective case series of 47 women with stage III and IV carcinoma ovary who underwent bowel resection, over the period of 5 years from Jan 2011 to Dec 2015. The disease free survival was assessed and the prognostic factors for disease free survival was also analysed by bivariate analysis. Results: In this cohort 64% (30/47) had primary debulking, 21% (10/47) had interval debulking and 15% (7/47) had secondary debulking. The mean period of follow up was 23 months (1 – 45 month). The mortality was 15% (7/47), while major morbidity like anastomotic leak were nil. The three variables considered for mortality were relaparotomy, paralytic ileus and surgical site infection. 6% (3/47) had relaparotomy, 21% (10/47) had paralytic iileus and 15% (7/47) had surgical site infection. The overall morbidity was 42.5% (20/47). A total 34% (16/47) of patients had stoma. 79% (37/47) patients had optimal debulking. Conclusion: Bowel resection in optimally selected cases of advanced carcinoma ovary is a good option with limited mortality and morbidity. Often, bowel resection is the only way to achieve optimal debulking.

Abstract:
The goal of the project is to develop an effective treatment planning computational tool for nanotube-mediated laser therapy that maximizes tumor destruction and minimizes tumor recurrence. Laser therapies can provide a minimally invasive treatment alternative to surgical resection of tumors. However, the effectiveness of these therapies is limited due to nonspecific heating of target tissue and diffusion limited thermal deposition which often leads to healthy tissue injury and extended treatment durations. These therapies can be further compromised due to induction of molecular chaperones called heat shock protein (HSP) in tumor regions where non-lethal temperature elevation occurs causing enhanced tumor cell viability and imparting resistance to chemotherapy and radiation treatments which are generally employed in conjunction with hyperthermia.

Abstract:
Endoscopic closure after endoscopic mucosal resection (EMR), endoscopic submucosal dissection (EMR) or endoscopic full-thickness resection (EFTR) is necessary to eliminate serious complications. Through-the-Scope clips are usually used in treating GI bleeding and perforation for their convenience and reliable outcome, but they are not ideal when the perforation size is larger than 2 cm since their opening width is limited. Several approaches are introduced to reinforce the performance of clips in regarding gathering edges of large defect by using endoloop and clips with double-channel endoscope [1]. Recently, an innovative endoscopic suturing technique using slipknot string and clips with single-channel endoscope has been reported, which resulted in shorter procedure time [2]. However, slipknot cannot maintain for a long time when exposing to distractions due to its poor holding strength. We have designed and fabricated an endoscopic clipping device and reported its initial ex-vivo results [3]. In this paper, a new suturing method is presented by using this device incorporated with a 4S-Modified Roeder (4SMR) knot, which enables such device to close large defect in a short time. Furthermore, the mechanical strength of 4SMR knot is also studied.

Abstract:
Laser therapies based on photochemical or photothermal mechanisms can provide a minimally invasive and potentially more effective treatment alternative to conventional surgical resection procedures by delivering prescribed optical/thermal doses to a targeted tissue volume with minimal damage to intervening and surrounding tissues. However laser therapy effectiveness is limited due to nonspecific excitation/heating of target tissue which often results in healthy tissue injury. Nanostructures targeted to tumor cells and utilized in combination with laser excitation can enhance treatment effectiveness by increasing thermal deposition and generating toxic photo-chemical mediators in the form of reactive oxygen species for targeted cell destruction.

Abstract:
A rising therapy for liver tumor treatment is the local delivery of Yttrium-90 (90Y) radiation via the injection of radioactive microspheres into the hepatic arteries. The elevated arterial blood flow supplying the liver tumor(s) hopefully directs the microspheres towards tumor cells rather than healthy liver tissue. While limited in precise control of the microspheres, the therapy has been shown to have positive response rates on tumors that are nonresponsive to chemotherapy or are disqualified for surgical resection or ablation. Thus, research studies seeking to improve clinical 90Y-microsphere therapy are crucial to advancing radiation oncologists’ ability to effectively treat the increasing number of patients afflicted with liver tumors1,2.

Abstract:
Ovarian cancers tend to recur in 15-70% cases. CA-125 - is a tumor marker used for monitoring therapeutic response, and in surveillance, for recurrent disease. However, it has a limited role as a persistent high level can signify either recurrence or persistence of residual tumor. Metastases from ovarian cancer primarily involve the peritoneum rather than parenchymal sites; thus, the presence of small-volume recurrence or metastatic deposits on the visceral surfaces poses a challenge for interpretation of CT and MR images. PET/CT utilizes its property of higher accumulation in malignant cells to provide both anatomic and functional information for diagnosing malignant tumors. Objectives: The objectives of the study were to find the correlation between PET/CT findings and final histopathological diagnosis after a secondary cytoreductive surgery in suspected ovarian cancer recurrences. Materials and Methods: PET/CT was done in cases with rising or above normal CA-125 and no radiological findings. These patients with abnormal PET/CT findings were taken up for a secondary cytoreductive surgery and histopathological proven were taken as the standard against which PET/CT positive findings was compared. Results: The mean age in our group of patients with suspected recurrence was 53 years (Range 39-74 years). Of the 52 patients with suspected recurrence, 40 patietnts with a PET-CT scan with findings suggestive of an avid uptake underwent surgery. 22 patients had serous histology, 12 mucinous and 8 had clear cell carcinoma. Stage-wise distribution at the time of primary surgery is as follows stage I-3, stage II-7, stage III-26, stage IV-4. Of the 40 patients who underwent a second look surgery 32 had histopathologically confirmed recurrence. PET-CT detected a total of 86 lesions in the 40 patients who underwent surgery. Of these, 38 were in the lymph nodes 28 in para-aortic and 10 in pelvic, 32 were peritoneal lesions and 14 were pelvic, 2 were metastatic in the parenchyma of liver. Detection of the lesion on PET-CT was size dependant, of the 9 lesions were missed on PET-CT, 7 were less than 0.5 cm. The mean diameter of the lesions detected was 2.2 cm (range 0.3-6.2 cm). PET-CT accurately identified 62 of 70 histopathologically proven lesions. The overall lesion-based sensitivity of PET-CT is 88.6%, specificity 56.2%, Positive predictive value being 72.1%, negative predictive value of 69.2%. Accuracy of detecting lesions greater than 1 cm is 78.6% (44 of 56 lesions). Conclusions: Corelation between PET/CT and histopathologicaldisease: k (cohen value) = 0.81 which suggests excellent correlation. For selected patients with ovarian cancer recurrence may benefit from a comprehensive radiographic imaging survey (PET-CT) at the time of even no or minimal CA-125 elevation in early detection and successful cytoreductive surgical resection and an increase in overall survival.
