Experience with laparoscopic adjustable gastric banding (la-band system) up to 8 years.

Morbid obesity occurs in 2-5% of the population in Western countries. Laparoscopic adjustable silicone gastric banding is a minimally invasive, adjustable and reversible procedure for the treatment of morbid obesity. The lap-band system was evaluated retrospectively in a series of 222 patients. Postoperative outcome and weight loss patterns at up to 8 years follow-up are presented. The most frequent late complications were a leak between the port and the catheter, which occurred in 21 patients (9.4%) and total and irreversible food intolerance due to pouch dilation and/or slippage, which occurred in 13 patients (5.8%). The postoperative BMI reductions are successful and stable after a follow-up of up to 96 months. The lap-band system seems an effective procedure for achieving appreciable and stable weight loss up to 8 years of follow-up and the complications and re-operation rates are acceptable. In 81% of the cases also, the patient is very satisfied with the results of the operation. From the 47.3% who found their quality of life before the operation bad or even devastating, 93% envoy life after the operation like never before.

The dramatic reality of biliary tract injury during laparoscopic cholecystectomy. An anonymous multicenter Belgian survey of 65 patients.

BACKGROUND: Most reports concerning the outcome of patients with biliary tract injury during laparoscopic cholecystectomy come from tertiary referral centers, and results could be very different in the everyday practice of community surgeons. OBJECTIVE: The objective is to define the presentation, mechanisms, results of treatment, and long-term outcome of biliary tract injuries during laparoscopic cholecystectomy in the setting of a community surgeon's practice. METHODS: An anonymous retrospective multicenter survey of 9,959 patients who underwent laparoscopic cholecystectomy was conducted by the Belgian Group for Endoscopic Surgery, composed mainly of community general surgeons. RESULTS: Sixty-five patients with bile duct injury were reported on; the incidence was 0.5%, varying from 0. 35 to 1.3% according to the experience of the surgeon. Thirty-four percent of ductal injuries occurred with experienced surgeons, often in association with local predisposing risk factors. Injury occurred in 87% of cases during dissection of the Calot triangle, with severe injury occurring in 46% of patients. Intraoperative cholangiography was performed in 34% of patients and was associated with a significantly improved operative detection rate of injury (68% vs 32%, p = 0.007). Operative detection of injury occurred in 45% of patients; diffuse bile ascitis was encountered postoperatively in 29%. The overall mortality was 9%, the postoperative biliary complication rate 31%, and the reintervention rate 14%. During a median follow-up of 49 months (range, 3-78 months), 20 of the 61 surviving patients (33%) had recurrent biliary strictures. Multivariate analysis demonstrated that the age of the patient (odds ratio: 0.893) and the presence of biliary peritonitis (odds ratio: 0.061) were independent predictive factors for mortality and that the age of the patient (odds ratio: 1.049) and the occurrence of postoperative biliary complications (odds ratio: 0.161) after the initial biliary repair were independent predictive factors for late biliary stricture. CONCLUSIONS: Biliary tract injury is associated with significant mortality and complications in the practice of Belgian community surgeons. Intraoperative detection of ductal injury by the routine use and a correct interpretation of intraoperative cholangiography improved outcome. The impact of the primary biliary repair on long-term outcome is an argument to refer these patients to specialized multidisciplinary experts. The results highlight the importance of surgical experience, proper selection of patients for laparoscopic cholecystectomy, and conversion to laparotomy in difficult cases.

Laparoscopic treatment of nonparasitic liver cysts: adequate selection of patients and surgical technique.

Results of laparoscopic fenestration in patients with a highly symptomatic solitary liver cyst (17 patients) or polycystic liver disease (PLD) (9 patients) were prospectively evaluated in a multicenter practice of general surgeons. Conversion to laparotomy was required in two patients because of inaccessible deep liver cyst in one and a diffuse form of PLD in the other. There was no mortality or major morbidity. Mean postoperative hospital stay was 4.6 days after successful laparoscopic procedures. During a mean follow-up of 9 months, 23% of the patients had recurrence of symptoms and 38% had radiographic reappearance of cysts. Factors predicting failure included previous surgical treatment, deepsited cysts, incomplete deroofing technique, location in the right posterior segments of the liver, and a diffuse form of PLD with small cysts. Adequate selection of patients and type of cystic liver disease and meticulous and aggressive surgical technique are recommended.
