ABSTRACT

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (LRYGB) are both effective surgical procedures to achieve weight reduction in patients with obesity. The trial objective was to merge individual-patient data from two RCTs to compare outcomes after LSG and LRYGB. METHODS: Five-year outcomes of the Finnish SLEEVEPASS and Swiss SM-BOSS RCTs comparing LSG with LRYGB were analysed. Both original trials were designed to evaluate weight loss. Additional patient-level data on type 2 diabetes (T2DM), obstructive sleep apnoea, and complications were retrieved. The primary outcome was percentage excess BMI loss (%EBMIL). Secondary predefined outcomes in both trials included total weight loss, remission of co-morbidities, improvement in quality of life (QoL), and overall morbidity. RESULTS: At baseline, 228 LSG and 229 LRYGB procedures were performed. Five-year follow-up was available for 199 of 228 patients (87.3 per cent) after LSG and 199 of 229 (87.1 per cent) after LRYGB. Model-based mean estimate of %EBMIL was 7.0 (95 per cent c.i. 3.5 to 10.5) percentage points better after LRYGB than after LSG  (62.7 versus 55.5 per cent respectively; P < 0.001). There was no difference in remission of T2DM, obstructive sleep apnoea or QoL improvement; remission for hypertension was better after LRYGB compared with LSG (60.3 versus 44.9 per cent; P = 0.049). The complication rate was higher after LRYGB than LSG (37.2 versus 22.5 per cent; P = 0.001), but there was no difference in mean Comprehensive Complication Index value (30.6 versus 31.0 points; P = 0.859). CONCLUSION: Although LRYGB induced greater weight loss and better amelioration of hypertension than LSG, there was no difference in remission of T2DM, obstructive sleep apnoea, or QoL at 5 years. There were more complications after LRYGB, but the individual burden for patients with complications was similar after both operations.

ABSTRACT

UNLABELLED: We studied developments in indication, operation time, conversion rate, morbidity, and mortality from the beginning of laparoscopic cholecystectomy. Between 1990 and 2002 we prospectively evaluated 4498 patients undergoing cholecystectomy (CE), of whom 79% were treated laparoscopically (lap). In 6.6%, the procedure had to be converted from laparoscopic to open cholecystectomy (con), and 14% were performed open from the beginning (open). During the above time period, the rate of open CE decreased steadily (49% in 1990 to 7.2% in 2002). The average operation time of lap CE remained constant with an average of 74 min (range 20-330). The conversion rate decreased in spite of broader indication for lap CE in even more complicated gallstone diseases, from an initial 9.4% to 2.5%. Among intraoperative complications in lap and con, bile duct lesions remained constant with 5/3856 (0.1%), bleeding which led to conversion decreased from 1.9% to 0.3%, and the rate of gall bladder perforation increased from 12% to 20.5%. Thirty-day morbidity was 2% in lap CE, 5% in con, and 11.5% in open. The mortality was 0% in lap, 0.7% in con, and 1% in open. CONCLUSION: Since the introduction of laparoscopic cholecystectomy the indication for this minimal-invasive operation steadily increased, the conversion-rate decreased and the complication-rate could be held low. Even with fast laparoscopic experience 7% of all cholecystectomies are technically difficult and remain to be carried out primarily in an open technique. The laparoscopic cholecystectomy has become the gold standard in the therapy of gallstone disease.
