Abstract

Laparoscopic sleeve gastrectomy (LSG) is the most frequently performed bariatric procedure in the world. The aim of the study was to evaluate outcomes after 10years. Patients who underwent LSG between 2005 and 2010 in a single center were retrospectively assessed, focusing mainly on the percentage of excess weight loss (%EWL) after 10years. Inadequate weight loss was defined as a %EWL < 50% or the need to perform a revisional bariatric surgery. Overall, 149 patients underwent LSG, with a median preoperative body mass index of 42.0 ± 6.5kg/m2. Ten patients (6.7%) underwent previous bariatric procedure. Patients eating behavior was described as volume eaters in 73 (49%), sweet eaters in 11 (7.4%) and both volume and sweet eaters in 65 (43.6%). Six patients died during follow-up and 25 patients were lost to follow-up, leaving 118 (79%) patients who completed full follow-up. Thirty-five patients (23.5%) needed a revisional bariatric surgery. For the 83 remaining patients, the mean %EWL was 35.9% at 10years, only 23 of 83 patients (27.7%) had a %EWL ≥ 50%. Thus 80.5% patients (95/118) experienced inadequate weight loss 10years after LSG. A lower %EWL after 1year was predictive for inadequate weight loss after 10years. Ten years after LSG, the rate of inadequate weight loss was high, reaching 80% of patients. Thirty percent of patients required a revisional bariatric procedure. New studies must try to identify patients who are good candidates for LSG and strategies to improve long-term outcomes.
