Abstract
Results: We recruited 400 patients. The mean±SD body mass index decreased to 40.6±3.0 after the first year and to 35.2±7.0 after 2 years. The average excess weight loss reduction was 48.2% after 1 year and 56.0% after 2 years. The excess weight loss reduction was inversely related to the initial weight: patients with an estimated weight excess of 50 kg or less (108 patients [27.0%]) had an excess weight loss reduction of 55% after 2 years; those with a weight excess of greater than 50 kg (292 patients [73.0%]) had an excess weight loss reduction of 44% (P= .004). We recorded 1 death (0.2%). Transient gastric occlusions (24 patients [6.0%]) and slippages (12 patients [3.0%]) were the most common complications. The devices used (Swedish adjustable gastric band and Lap-Band) were similar in terms of correction of obesity and morbidity.
