Endoscopic axillary exploration and sentinel lymphadenectomy

Background: Minimally invasive approaches have changed the practice of surgery in several specialties. The purpose of this study was to develop a reproducible endoscopic technique for the evaluation of the axilla in breast cancer patients. Methods: A total of 23 patients with biopsy-proven breast carcinoma were enrolled. Patients were positioned in the supine position with the ipsilateral arm abducted at 90°. A 1-cm skin incision was made at the superior aspect of the axilla. Dissection was carried bluntly to the lateral border of the pectoralis major. A balloon distention device was inserted into the tract and distended under endoscopic vision to create a working space. Insufflation was initiated up to a pressure of 8 mmHg. A 30° laparoscope was introduced for visualization of axillary contents. One or two additional 5-mm cannulas were placed as needed under direct visualization. Manipulation of axillary contents was performed, and in 19 patients a sentinel node identification technique was applied. Results: In all patients, using insufflation and minimal instrument dissection, the axillary vein, long thoracic, and thoracodorsal nerves were found in their usual anatomical locations. Utilizing blunt and sharp dissection, the axilla was thoroughly inspected, and individual lymph nodes were easily identified and extracted. In 11 of 19 patients, a sentinel node or blue dye was identified using isosulfan blue. There was a procedure concordance of 84%, and there were no complications. Conclusions: We describe a novel endoscopic technique for the evaluation of the axilla in breast cancer patients. This technique allows (a) creation of a minimally invasive working space within the axilla, (b) recognition of key axillary anatomic landmarks, and (c) instrument manipulation within the axilla to identify and extract lymph nodes, and apply the sentinel node technique. This is the first report of a minimally invasive approach to axillary exploration to employ sentinel lymph node mapping. Received: 22 April 1996/Accepted: 15 May 1998

Subfascial endoscopic perforator vein surgery: who benefits?

The advent of minimally invasive endoscopic surgery has rekindled interest in perforator vein ligation. Subfascial endoscopic perforator vein surgery (SEPS) utilizes techniques to interrupt incompetent perforators under direct vision using an endoscopic videocamera and instrumentation placed through small ports remote from the active ulcer or area of diseased skin. The safety and early efficacy of SEPS has been established in several studies, and it yields lower wound complication rates than observed with open surgical techniques such as the Linton procedure. Available results confirm the superiority of SEPS over open perforator ligation, but do not address the its role in the surgical treatment of advanced chronic venous insufficiency (CVI) and venous ulceration. Ablation of superficial reflux by high ligation and stripping of the greater saphenous vein with avulsion of branch varicosities is concomitantly performed in the majority of patients undergoing SEPS. The clinical and hemodynamic improvements attributable to SEPS thus are difficult to ascertain. As with open perforator ligation, clinical and hemodynamic results are better in patients with primary valvular incompetence (PVI) than in those with the postthrombotic (PT) syndrome. Until prospective, randomized, multicenter clinical trials are carried out to answer lingering questions regarding the efficacy of SEPS, the procedure is recommended in patients with advanced CVI secondary to PVI of superficial and perforating veins, with or without deep venous incompetence. The performance of SEPS in patients with PT syndrome remains controversial.     

Closed Subfascial Ligation of Incompetent Perforating Veins of the Lower Extremities

The purpose of this study was to determine the effectiveness of minimally invasive surgical procedures for interrupting incompetent perforating veins of the lower limb. A closed subfascial ligation was performed in 20 patients who had incompetent perforating veins in 28 limbs as diagnosed by a clinical examination and duplex scanning. Two small transverse incisions measuring 5–10mm in length were made on both sides of the incompetent perforating vein. Using an aneurysmal needle, a suture (polypropylene No. 1) was placed in the subfascial plane to encircle the incompetent perforating vein from all directions. Next, this suture was tied through two incisions to ligate this perforator. The mean follow-up period was 26 months. The ligation of the incompetent perforators was successful in 27 of 28 limbs and no wound complications were observed. A closed subfascial ligation of incompetent perforating veins of the lower limbs is thus considered to be easy to perform, not overly invasive, safe, and to also have very encouraging results.     

Axilloscopy and endoscopic sentinel node detection in breast cancer patients

Background: Sentinel node biopsy is a promising technique that allows the axillary status of breast cancer patients to be predicted with high accuracy. Reducing false negative results remains a major challenge for the improvement of this procedure. Furthermore, new techniques are required to achieve axillary clearing with less morbidity in cases of unsuccessful mapping or multicentric carcinoma. We analyzed whether axilloscopy and endoscopic sentinel node biopsy is a feasible procedure for visualization of the axillary space and resection of the sentinel node using endoscopic techniques. Methods: Following blue dye–guided lymphography and liposuction of the axillary fat, endoscopic axillary sentinel node biopsy was performed in 35 breast cancer patients. We then assessed the exposure of anatomical landmarks, the detection rate of the sentinel node, the false negative rate, and the accuracy of consecutive axillary clearing. Results: In almost every case, an excellent anatomical orientation was achieved. The detection rate for the sentinel node was 83.3%. In one case, the sentinel node did not reflect the status of the residual axilla. A mean number of 17.1 lymph nodes was harvested at consecutive axillary clearing. Conclusions: Axilloscopy and endoscopic sentinel node biopsy, following liposuction of the axillary fat, is a feasible procedure that allows identification and minimally invasive resection of the sentinel node with high accuracy. The endoscopic approach might help to minimize the pitfalls of sentinel node biopsy by visualizing the axillary space. In future, it may become a technique that enables minimally invasive axillary clearing when complete lymphadenectomy is required.

Endoscopic endocrine surgery in the neck

Background: The fervor surrounding minimally invasive surgery, which began with laparoscopic cholecystectomy in the late 1980s, has spread to nearly all surgical specialties. Methods: After experimental success in an animal model, we recently performed our first case of endoscopic subtotal parathyroidectomy in a 37-year-old man. The patient, who had a history of severe pancreatitis and pancreatic calculi, was diagnosed as having hyperparathyroidism. The option of endoscopic parathyroidectomy was proposed and accepted. After placing the first trocar directly under the platysma, a space was created by bluntly dissecting with the tip of a 5-mm endoscopic camera. Four parathyroid glands were identified, and after a frozen-section diagnosis of parathyroid hyperplasia, three-and-one-half of the glands were resected. Results: The patient developed slight hypercarbia and subcutaneous emphysema during the procedure, but no other problems were noted. His postoperative course was otherwise unremarkable. Conclusions: This is the first case reported of an endoscopic parathyroidectomy. This experience makes us optimistic about the future of endoscopic neck surgery.

Laparoscopic repair of missed blunt diaphragmatic rupture using a prosthesis

A 54-year-old man underwent a therapeutic laparoscopy for giant diaphragmatic rupture complicating a blunt trunk trauma that had occurred 13 months earlier. Laparoscopy revealed a left hemidiaphragm 12-cm defect with an intrathoracic herniation of the omentum, the entire gastric fundus, the splenic flexure of the colon, and the two upper thirds of the spleen. The defect was not suitable for primary suture due to the diaphragmatic edges retraction. We repaired the hernia using a large polypropylene mesh covering the defect with 2-cm overlap. There was no intraoperative surgical or anesthetic complication. Postoperative course was uneventful and 3-month follow-up confirmed the healing of the diaphragmatic hernia. This case is discussed regarding the safety of the procedure, the best minimally invasive approach, and technical aspects of the repair. Received: 6 June 1997/Accepted: 11 August 1997     

Role of Subfascial Endoscopic Perforator Surgery (SEPS) in Management of Perforator Incompetence in Varicose Veins : A Prospective Randomised Study

The study was carried out to compare the efficacy of subfascial endoscopic perforator surgery (SEPS) and open subfascial ligation of perforators in varicose veins. This study was conducted on 100 patients of varicose veins from January 2006 to December 2010. Clinical scoring and color Doppler were performed in all the patients before surgery. Patients were divided into two groups: Group A and Group B alternately. Management of the perforators was done by subfascial endoscopic perforator surgery (SEPS) in Group A and by open subfascial ligation of perforators in Group B. Fifty patients were treated in each group. All the patients underwent ligation of incompetent saphenofemoral junction with stripping of long saphenous veins wherever the junction was incompetent with multiple ligation of superficial prominent veins. SEPS was done by two-port method without any tourniquet or balloon dissector. Total numbers of perforators ligated were 178 in Group A and 136 in Group B. Patients in both the groups got symptomatic relief of symptoms, but ulcer healing in 33 % patients in Group A was faster as compared to Group B. However, at 3 months of follow-up the ulcers healed in all the patients in both groups. Incidence of wound infection was higher in group B (16 %) as compared to group A (0 %). There were residual perforators in 8 % of patients on color Doppler at 3 months of follow-up in Group B while there was no residual incompetent perforator in Group A. Subfascial endoscopic perforator vein surgery is a safe and effective method for treating incompetent perforating veins. The number of perforators ligated in SEPS was more as compared to the open subfascial ligation group. Possibly some perforators may be missed on Doppler localization and missed ligation, which may be a cause of future recurrence in varicose veins. Early relief of symptoms in terms of ulcer healing was better in the SEPS group with less wound complication rate; however, all the ulcers healed in both the groups at 3 months of follow-up. Cosmetic results were equal in both the groups. Major advantage of SEPS was less incidence of wound complications and less incidence of residual incompetent perforators. Hence, SEPS should be added for the management of perforators along with conventional surgery in varicose veins.     

Transgastrostomal endoscopic surgery for early gastric carcinoma and submucosal tumor

Background: Laparoscopic intraluminal surgery of the stomach is now widely used for a lesion on the posterior wall. However, this procedure has some technical limitation related to the intricate introduction of the surgical instruments into the gastric lumen. In this article, we report our newly developed technique of transgastrostomal endoscopic surgery that overcomes this limitation and is also suitable for full-thickness gastric wall resection of a lesion in the wall. Methods: After making a 4-cm-long temporary gastrostomy, a Buess-type endoscope is inserted into the gastric lumen through the gastrostomy. The operation is performed inside the gastric lumen under video camera guidance using electrocautery, scissors, and forceps. After resection, the wound in the mucosa or the wound after full-thickness resection is endoluminally sutured. Mucosal resection was performed in six cases of early gastric carcinoma, two cases of atypical epithelium, and one case of ectopic pancreas. Full-thickness wall resection was performed in four cases of a leiomyoma. Results: In all 13 cases, the lesion could be precisely located by the video camera. All lesions were then resected endoluminally. The mean duration of the operation was 148 min. The postoperative course in all cases was uneventful. Conclusions: Transgastrostomal endoscopic surgery is minimally invasive and an efficient tissue-preserving technique for the removal of early gastric carcinoma or submucosal tumor.

Safety of adrenal vein ligation during endoscopic adrenalectomy

Endoscopic adrenalectomy has been recommended for the treatment of several benign adrenal diseases. The safety of this procedure largely depends on a careful surgical dissection and appropriate hemostatic technique. An established slipknotting technique was employed to control the main adrenal vein in a consecutive series of 14 patients undergoing endoscopic adrenalectomy. The operative steps to ligate the adrenal pedicle are described. A Medline search also was conducted to identify all reported bleeding episodes associated with this procedure. All attempted ligatures of the main adrenal vein were completed successfully by the described technique, and none of our patients required perioperative blood transfusion. Twenty-eight episodes of bleeding collected from the literature were analyzed. Hemorrhagic accidents related to dislodgement of clips were documented at least in three patients. The cause of bleeding was unspecified in 10 patients. Extracorporeal ligation of the main adrenal vein is feasible, safe, and advisable to prevent the occurrence of hemorrhage during endoscopic adrenalectomy.

Laparoscopic treatment of duodenal carcinoid tumor

A 46-year-old man with epigastralgia and slight elevation of urinary 5-hydroxyindole acetic acid (5HIAA) was found to have a well-demarcated carcinoid tumor in the duodenal bulb. The tumor measured 8 mm in size, and showed submucosal involvement but no metastasis to the liver and regional lymph nodes. After laparoscopic exposure and lifting of the duodenal wall around the tumor, wedge resection of the duodenal bulb including the tumor was performed successfully with a laparoscopic endostapler under direct endoscopic control. The postoperative course of the patient was uneventful. Laparoscopic wedge resection of the duodenum would be an appropriate minimally invasive treatment for selected duodenal neoplasms with special preoperative assessments and intraoperative considerations.

Endoscopic subfascial discission of perforating veins

Summary The insufficiency of perforating veins is thought to be crucial in the pathogenesis of varicose and postphlebitic ulcers as well as postoperative varicose vein recurrence. Their eradication is a valid and effective therapeutic concept. No presently available technique has yielded satisfactory results, hence our efforts to develop a new method: the endoscopic subfascial discission of perforating veins (ESDP). It involves performing a small incision in an area remote from the point of trophic disturbance and allows the operator to accurately and atraumatically perform a subfascial discission of the perforating veins where they join the deep veins under direct endoscopic control. Our initial experience with the technique showed promising results: 78%–93% good and very good results depending on the clinical parameters applied. These are the results of a follow-up period of up to 14 months. During that time, none of our patients developed a complication or recurrence. Our technique has many advantages over traditional techniques of perforator vein eradication: (1) more accurate localization; (2) improved wound healing, (3) dependable occlusion; (4) immediate postoperative mobilization of the patient. We feel that ESDP represents a major advance in the development of better methods of subfascial perforator vein eradication. Greater experience and a longer follow-up period will, however, be required to confirm this initial observation.     

Die Wertigkeit der endoskopischen subfaszialen Perforansdissektion (ESDP)

Surgery performed on incompetent perforator veins with “historical techniques”, such as the Linton operation, was associated with a relatively high complication rate. Hauer introduced a new method of endoscopic subfascial perforator vein interruption (SEPS) in 1985 and also developed it further; the indications for this endoscopic procedure were subsequently widened to range from primary varicose veins to advanced stages of chronic venous insufficiency. Few follow-up data from prospective randomized trials are available, and most clinical data refer to widely differing patient populations, so that the results are not comparable. In the case of uncomplicated superficial venous disease there are method-specific complications that should not be overlooked. As a result, the value of subfascial endoscopic perforator vein surgery relative to other methods is regarded with increasing criticism. Venous outflow obstruction from deep vein thrombosis was expected to be an ideal indication; however, data from the NASEPS Registry have demonstrated no benefit of the endoscopic procedure during follow-up. Eradication of main stem saphenous reflux will result in insignificant perforator vein reflux in approximately 80%. The haemodynamic consequences of incompetent perforator vein interruption have not yet been adequately documented. At this time, the main area of application of SEPS is in the treatment of multiple insufficient perforator veins of the medial calf and additional focal symptoms of chronic venous insufficiency, especially combined with paratibial fasciotomy and additional epifascial varicose vein surgery.     

Laparoscopic cecal ligation and puncture in the rat

Background: We describe a technique of laparoscopic cecal ligation and puncture (CLP) in the rat analogous to open CLP which may facilitate the study of minimally invasive surgery (MIS) and peritonitis. Methods: Forty-four rats were randomized to either laparoscopic or open CLP and their 3-day mortality was recorded. Autopsies were performed for peritoneal fluid cultures, measurement of the length of ligated cecum, and scoring of the degree of cecal necrosis. Results: Laparoscopic CLP required slightly longer operating times compared to open CLP (average 15.6 vs 13.1 min, p= 0.002). Three-day postoperative mortality was 36.4% and 22.7% for open and laparoscopic CLP, respectively (p= NS). There were no differences in the length of ligated cecum or the cecal necrosis score between the open and laparoscopic CLP groups. Conclusion: Laparoscopic CLP is feasible and produces a fecal peritonitis with similar characteristics to those of traditional open CLP. Received: 3 July 1996/Accepted: 7 January 1997
