Abstract：
BACKGROUND:While numerous promising short-term results of open gastric bypass for morbid obesity were published, the long-term outcome of earlier versions was somewhat disappointing. Thus, it was not until 1993 that this procedure was reintroduced with current modifications and now performed laparoscopically. Published long-term results of gastric bypass are still lacking. METHODS:Out of an original population of 195 patients, we retrospectively analyzed the outcome of 98 patients (82 women, 16 men, mean age 32 years [range 17-54], mean weight 132 kg [range 65-200], mean BMI 46.6 kg/m2) operated on in Erlangen with mean follow-up 22.9 years (range 16.5-25.4). 3 different bariatric operations were performed: horizontal gastroplasty (HGP, n=18), stapled Roux-en-Y gastric bypass (S-RYGBP, n=14) and transected Roux-en-Y gastric bypass (T-RYGBP, n=66). BMI and percentage of excess weight loss (%EWL) were calculated at time 0, and after 1, 2, 3, 10, 15, 20 and 25 years. RESULTS:Statistically significant weight loss was found for the whole patient population at every postoperative time-point compared to preoperative values. Maximal weight loss was achieved mainly during the first 3 years. However, initial and long-term outcome after HGP was significantly worse than after S-RYGBP or T-RYGBP. Gender did not significantly influence the results. CONCLUSION:Traditional open gastric bypass resulted in acceptable and safe long-term weight reduction. It may be assumed that laparoscopic gastric bypass with modern tiny pouch volumes based on the lesser curvature achieves even better and life-long weight reduction.
