Abstract:

Abstract BACKGROUND: Lasers have a long history in neurosurgery, yet bulky designs and difficult ergonomics limit their use. With its ease of manipulation and multiple applications, the OmniGuide CO2 laser has reintroduced laser technology to the microsurgical resection of brain and spine lesions. This laser, delivered through a hollow-core fiber lined with a unidirectional mirror, minimizes energy loss and allows precise targeting. OBJECTIVE: To analyze resections performed by the senior author from April 2009 to March 2013 of 58 cavernous malformations (CMs) in the brain and spine with the use of the OmniGuide CO2 laser, to reflect on lessons learned from laser use in eloquent areas, and to share data on comparisons of laser power calibration and histopathology. METHODS: Data were collected from electronic medical records, radiology reports, operative room records, OmniGuide CO2 laser case logs, and pathology records. RESULTS: Of 58 CMs, approximately 50% were in the brainstem (30) and the rest were in supratentorial (26) and intramedullary spinal locations (2). Fifty-seven, ranging from 5 to 45 mm, were resected, with a subtotal resection in 1. Laser power ranged from 2 to 10 W. Pathology specimens showed minimal thermal damage compared with traditionally resected specimens with bipolar coagulation. CONCLUSION: The OmniGuide CO2 laser is safe and has excellent precision for the resection of supratentorial, brainstem, and spinal intramedullary CMs. No laser-associated complications occurred, and very low energy was used to dissect malformations from their surrounding hemosiderin-stained parenchymas. The authors recommend its use for deep-seated and critically located CMs, along with traditional tools.

Abstract:

Objective The feasibility of endovascular resection of highly calcified aortic valves has already been demonstrated by our group. Different endovascular and intracardiac tractability methods were applied. In this study, these technologies were analyzed comparing the tractability, the resection time, and the lesions in the surrounding tissue. Methods All aortic valve resections (seven human hearts and 21 porcine hearts) were performed using a Thulium:YAG laser (continuous wave, wavelength of 2.01 μm, 20 watts power rating). In the first resection system, the laser fiber was controlled by a free in-lying flexible endoscope (Ø 2.5 mm, length of 600 mm). The distal part of the endoscope (40 mm) was moved in one plane by proximal manual control (three degrees of freedom). The resection system was separated into defined rooms assigning one room for one tool. The fiber was controlled by the above-mentioned endoscope (*) (three degrees of freedom). The third resection system was a mechanical microactuator carrying the laser fiber (three degrees of freedom). The fourth resection system contains a rotatable inlay with defined rooms and a newly designed nitinol (NiTi) microactuator that controlled the laser fiber (four degrees of freedom). The resection time per leaflet was measured in minutes. Gross anatomy and histology in the surrounding tissue were evaluated. Results The resection time in approaches 1, 2, 3, and 4 was 5.5 ± 2.3 minutes, 7.4 ± 2.7 minutes, ± 6.6 minutes, and2.3 ± 1.2 minutes, respectively. The gross anatomy and histology of collateral damages revealed only superficial lesions of the surrounding tissue. The amount of lesions and the resection time were lower in the fourth approach with four degrees of freedom. Conclusions This analysis demonstrated that a precise tractability with four degrees of freedom is necessary for a faster and safer endovascular resection of the aortic valve. The analysis will help to optimize the ongoing development of the endovascular and intra-cardiac resection technology.

Abstract:

— Laser treatment of benign prostatic hypertrophy (BPH) has gradually become more widespread over the last few years. In the USA it is considered an alternative to endoscopic resection as far as insurance payments are concerned. Different methods are used but the most common and suitable one for urologists is the removal and coagulation of the prostatic tissue under visual control (VLAP or ELAP). The Authors report their personal experience in this type of treatment where good results are due to: 1) combination of a powerful, stable laser source 2) durable side-emission contact fibre 3) laser resector, which also in the absence of epicystostomy maintains a good flow during the operation. However, “laser resection” should still be considered an experimental procedure to be used for randomised protocols or on selected patients (high risk of bleeding, Jehovah's witnesses, carriers of pace-maker, etc.).

Abstract:

Many procedures have been described for the resection of plantar calcaneal spurs as treatment of heel spur syndrome and chronic plantar fasciitis. Most of these techniques involve a medial incision of between 2 and 6 cm for adequate exposure of the calcaneal spur. This article describes a new technique for resecting a calcaneal spur with a smaller medial incision using the holmium:yttrium-aluminum-garnet (Ho:YAG) laser. This laser permits adequate resection of a plantar calcaneal spur as well as coagulation of the bone and surrounding tissues. This minimally invasive procedure has been used with good results over the past year by the senior author (W.K.S.) for the resection of calcaneal spurs. (J Am Podiatr Med Assoc 91(3): 142-146, 2001)

Abstract:

Abstract Tumors arising from the minor salivary glands in the larynx are rare. The most common tumors occurring here are adenoid cystic carcinomas.1 Among the benign tumors, pleomorphic adenoma is the most common.1 We present a case of subglottic pleomorphic adenoma which was managed by endolaryngeal endoscopic CO2 laser surgery. Laser as a primary treatment modality for the treatment of subglottic pleomorphic adenomas has not been well-described, as only one case has been reported in literature using this modality.

Abstract:

Aims and background The neodymium: yttrium-aluminium-garnet (Nd:YAG) laser has been successfully employed in parenchyma-sparing resection of pulmonary nodular lesions. We report our experience with limited resection using a noncontact Nd: YAG laser applied through a thoracotomic approach. Methods During the period March 1987-October 1993, we performed parenchyma-sparing resections of 66 pulmonary nodular lesions with a noncontact Nd:YAG laser in 47 patients. Nodules were approached through postero-lateral thoracotomy (n= 40), median sternotomy (n= 5) or staged bilateral thoracotomy (n= 2). Fifty-two lesions were located in a peripheral position and the others (n= 14) at various depths within the parenchyma. Results Fifteen lesions were benign: hamartoma (n= 5), chronic pneumonic infiltrate (n= 3), tuberculoma (n= 3), asbestosis (n= 2), Wegener's granuloma (n= 1). Twelve lesions were attributable to primary lung cancer and 33 were metastatic lesions. Another 6 lesions turned out to be necrotic metastases following chemotherapy. There were no perioperative deaths. Pulmonary re-expansion was shortly obtained: mean drainage time was 4.31 ± 3.9 days. Only one patient presented a prolonged drainage time (11 days); in this case, the air leak was successfully treated by tissue glue sealant trans-drainage infiltration. Follow-up ranged from 2 to 96 months. No case of relapse on the resection site has been observed. Conclusions The results suggest that Nd:YAG laser resection is safe and worthwhile in patients with multiple lesions and borderline pulmonary function.

Abstract:

Abstract Ventral spinal tumors are surgically challenging because the tumor resection should minimize spinal cord and nerve root manipulation to minimize morbidity, while providing access to a complete tumor resection. The CO2 laser has been useful in resection of central nervous system tumors, but little is described about the method used to resect spinal tumors.1 This video demonstrates the removal of a ventral cervical spinal meningioma using the CO2 laser. A 62-yr-old man presented with progressive paresthesias, gait instability, and urinary frequency. A 1-cm intradural extramedullary mass at C5 showed severe spinal cord compression. Patient consent was obtained prior to performing the procedure. A posterior lateral approach is shown, with a bone removal corridor created at C5 for accessing the tumor ventrally. A right-sided facetectomy and pediculectomy at C5 were performed being flush with the posterior vertebral body. A dural opening positioned laterally provided a working corridor between C5 and C6 nerve rootlets. Lateral portions of tumor were excised in wedge-shaped slices starting laterally and working medially. These slices created a successive and enlarging space to safely allow piecemeal tumor dissection and removal, while limiting retraction upon the spinal cord. The CO2 laser was used to cauterize the tumor capsule, create wedge resections of tumor, and coagulate the final dural attachment. The pathology was a meningioma WHO Grade I. The patient did well, with resolution of parasthesias and ataxia. The CO2 laser technique allowed for limited spinal cord retraction throughout the tumor resection and gross total resection of the tumor was achieved.

Abstract:

This operative technique video demonstrates laser microsurgery for brainstem cavernous malformations (CMs). In case 1 we demonstrate CO2 laser microsurgery for a symptomatic pontine CM using far lateral craniotomy and olivary zone entry. Case 2 demonstrates the subtemporal approach and removal of a paratrigeminal CM, and case 3 is a dorsal midbrain CM. We illustrate several advantages of laser microsurgery including improved visualization in narrow corridors, precise cutting with reduced thermal damage, and effective sealing of small vessels. Over the past decade at Stanford University School of Medicine, over 120 brainstem CMs have been removed using laser microsurgery with good results.The video can be found here: https://youtu.be/DwwqWGv_vzo.

Abstract:

OBJECTIVEThe CO2 laser has been used on an intermittent basis in the microsurgical resection of brain tumors for decades. These lasers were typically cumbersome to use due to the need for a large, bulky design since infrared light cannot be transmitted via fiber-optic cables. Development of the OmniGuide cable, which is hollow and lined with an omnidirectional dielectric mirror, has facilitated the reintroduction of the CO2 laser in surgical use in a number of fields. This device allows for handheld use of the CO2 laser in a much more ergonomically favorable configuration, holding promise for microneurosurgical applications. This device was introduced into the authors’ practice for use in the microsurgical resection of skull base tumors, including vestibular schwannomas.METHODSThe authors reviewed the initial 41 vestibular schwannomas that were treated using the OmniGuide CO2 laser during an 8-month period from March 2010 to October 2010. The laser was used for all large tumors, and select medium-sized tumors were treated via both the translabyrinthine and retrosigmoid approaches. The estimated time of tumor resection and estimated blood loss were obtained from operating room records. Data regarding complications, facial nerve and hearing outcomes, and further treatment were collected from hospital and clinic records, MRI reports, and direct review of MR images. Time of resection and blood loss were compared to a control group (n = 18) who underwent surgery just prior to use of the laser.RESULTSA total of 41 patients with vestibular schwannomas were surgically treated. The median estimated time of tumor resection was 150 minutes, and the median estimated blood loss was 300 ml. The only operative complication was 1 CSF leak. Thirty-eight patients had normal facial nerve function at late follow-up. The median MRI follow-up was 52 months, and, during that time, only 1 patient required further treatment for regrowth of a residual tumor.CONCLUSIONSThe OmniGuide CO2 laser is a useful adjunct in the resection of large vestibular schwannomas. This device was used primarily as a cutting tool rather than for tumor vaporization, and it was found to be of most use for very large and/or firm tumors. There were no laser-associated complications, and the results compared favorably to earlier reports of vestibular schwannoma resection.

Abstract:

AbstractOn the basis of the authors' experience with 20 patients, CO2 laser resection of palatal tumours has proved to be a good alternative to conventional surgical resection. The CO2 laser beam permits precise resection, due to only slight intra-operative bleeding coupled with use of the operating microscope. Wound healing is good and post-operative pain remarkably little.

Abstract:

Abstract The value of laser resection was assessed in the last 50 of 128 consecutive cases of pediatric spinal lipoma. In this series, there was no mortality. No patient suffered increase in neurological or urological deficit. Postoperatively, 8 of 20 patients with prior motor deficit (40%) had substantially improved motor function. Two of 17 previously incontinent patients became continent of urine (12%). Use of the CO2 laser reduced the length of operation, the intraoperative blood loss, and the degree of manipulation of the spinal cord and nerve roots. Most of the fat could be removed successfully from the liponeural junction, permitting more nearly anatomical removal of the intramedullary component of the lesion and greater ease in replacing the cord into a reconstructed arachnoid-dural canal. In the authors' opinions, proper management of the patient with spinal lipoma now requires early prophylactic resection of the lipoma and untethering of the spinal cord.

Abstract:

Endoscopic laser resection of early (T1) laryngeal carcinoma has been advocated as an alternative to radiotherapy. Heretofore, the voice characteristics following this procedure have been addressed in only one review, which included patients treated by irradiation and laser resection. We present the first review of voice findings in 22 patients treated only by endoscopic laser resection of their vocal cord carcinomas. Laser resection of selected vocal cord carcinomas produced voice function results acceptable to the patients and was rated by them to be normal to almost normal. Speech pathologists rated the voices to be near-normal to mildly abnormal. Voices after laser resection of vocal carcinoma exhibited a slightly higher fundamental frequency, a decrease in intensity and phonatory duration, and markedly higher laryngeal airway resistance. The percentage of voicing showed little deviation from normal, as did mean percentage of perturbations.

Abstract:

Laser excision of early selected cancers of the oral cavity and pharynx is a well accepted and reported treatment. Postoperative radiation therapy is employed in patients with unfavorable pathologic findings and in patients expected to have a high recurrence and metastatic rate. In most patients the combination of laser excision and postoperative radiation therapy is well tolerated and results in satisfactory healing, excellent tumor control, and high-level posttreatment function. This report discusses the treatment and results in 28 patients treated for early cancer of the oral cavity and pharynx. The local control rate of 77% compares favorably with the reported results following either conventional or laser excision of these lesions. The overall complication rate was 39%, with a 25% rate for patients not receiving postoperative radiation therapy, and a 58% complication rate for patients treated with postoperative radiation.

AbstractObjectives:The choices made by patients offered treatment for early laryngeal cancer with radiotherapy or transoral laser resection were reviewed.Methods:A prospective review was conducted of all patients diagnosed and treated for early laryngeal carcinoma from December 2002 to September 2009 at the Leeds Teaching Hospitals NHS Trust. A total of 209 patients with tumour stage T1 or T2 laryngeal cancer were treated; each new patient suitable for radiotherapy or transoral laser resection was seen jointly by the clinical (radiation) oncologist and head and neck surgeon, and offered the choice of treatment.Results:Of the patients, 47.4 per cent were given a choice between radiotherapy and transoral laser resection; 51.2 per cent were advised to have radiotherapy, and there were no records for the remaining 1.4 per cent. From those given the choice, 59.6 per cent chose transoral laser resection (p < 0.02 (t-test)) and 35.4 per cent chose radiotherapy.Conclusion:When given the choice, a statistically significant majority of patients choose transoral laser resection rather than radiotherapy.

Abstract:

Summary An “in vitro” experimental study has been carried out on 70 extracted teeth. A laser resection of the root apex has been carried out with diode laser beam with a wavelength of - 810 ± 10 nm. Sequentially a radiation with increasing power has been applied, as follows: 1,3 W, 2W, 3W, 4W, 5W, 6W, 7W, in electro surgery mode. Successful resection of the tooth apex has been performed at: 3W; 4W; 5W; 6W and 7W power. It was established that when laser resected the tooth apex carbonizes.

Abstract:

The authors have developed four different types of endolaryngeal laser resections for the treatment of larynx carcinomas. These new techniques are based on traditional concepts employed in partial larynx resections. From 1986 onward, 110 patients with laryngeal cancers were treated by endoscopic laser surgery. One hundred six patients were operated on for cure and 4 for palliation. In 9 cases of T3 tumor, complete removal of the tumor was not possible, requiring total laryngectomy. In all T2 cancers of the glottis and subglottis (n = 36), a total resection was possible. Additional staged neck dissection was performed in 16 cases, and postoperative radiotherapy in 10 cases. Follow-up investigations of the patients treated for cure (n = 106) cover a period of 3 to 42 months (mean, 22 months). These revealed 6 recurrences in the larynx, which were treated by laryngectomy. Recurrences in the cervical nodes were seen in 2 patients following resection of a supraglottic tumor and a subglottic tumor, respectively. Seven patients could not be followed up, 4 patients died of intercurrent disease, and 87 patients are alive and free of tumor. At present the number of recurrences and the rate of survival show no significant difference from those previously reported after conventional surgery. The phonatory function is not always predictable and still remains to be investigated. The authors believe that laser surgery may obviate the need for total laryngectomies in selected cases of laryngeal cancer, especially in T2 tumors. However, T3 tumors should not be treated by endolaryngeal laser surgery.

Abstract:

Retrospective evidence supports the value of optimal cytoreductive surgery in the initial therapy of patients with advanced ovarian cancer. Specialized procedures, including radical pelvic surgery, bowel resection, and diaphragm resections, are frequently necessary to accomplish optimal cytoreduction. Cytoreduction and total gross tumor removal are possible more frequently with new surgical instruments such as the Cavitron ultrasonic surgical aspirator and argon beam laser. Pelvic and periaortic lymph node resection is an important aspect of cytoreductive surgery, and systematic removal of grossly uninvolved lymph nodes may improve survival. Secondary cytoreductive surgery appears to benefit a select group of patients.
