title: Review of long-term weight loss results after laparoscopic sleeve gastrectomy.
abstract: Sleeve gastrectomy (SG) has gained enormous popularity both as a first-stage procedure in high-risk super-obese patients and as a stand-alone procedure. The objective of this study was to evaluate the long-term weight loss results after SG published in the literature and compare them with the well-documented short-term and mid-term weight loss results. A detailed search in PubMed using the keywords "sleeve gastrectomy" and "long-term results" found 16 studies fulfilling the criteria of this study. A total of 492 patients were analyzed, with a follow-up of at least 5 years after laparoscopic sleeve gastrectomy (LSG) (373 at 5 years, 72 at 6 years, 13 at 7 years, and 34 at 8 or more years). Of the total number of patients, 71.1% were women (15 studies, n = 432 patients). Mean patient age was 45.1 years (15 studies, n = 432 patients). Mean preoperative body mass index in all 16 studies was 49.2 kg/m(2). The mean percentage excess weight loss (%EWL) was 62.3%, 53.8%, 43%, and 54.8% at 5, 6, 7, and 8 or more years after LSG, respectively. The overall mean %EWL (defined as the average %EWL at 5 or more years after LSG) was 59.3% (12 studies, n = 377 patients). The overall attrition rate was 31.2% (13 studies). LSG seems to maintain its well-documented weight loss outcome at 5 or more years postoperatively, with the overall mean %EWL at 5 or more years after LSG still remaining>50%. The existing data support the role of LSG in the treatment of morbid obesity.
