BackgroundThis retrospective study evaluated long-term weight loss, resolution of comorbidities, quality of life (QoL), and food tolerance after laparoscopic sleeve gastrectomy (LSG).MethodsBetween January 2003 and July 2008, 102 patients underwent LSG as a sole bariatric operation. A retrospective review of a prospectively collected database was performed. Demographics, complications, and percentage of excess weight loss (%EWL) were determined. Quality of life was measured using Medical Outcomes Survey Short Form 36 (SF-36) and Bariatric Analysis and Reporting Outcome System (BAROS) questionnaires, which were sent to all patients. The food tolerance score (FTS) was determined and compared with that of nonobese subjects.ResultsA total of 83 patients (81.4%) were eligible for follow-up evaluation. Their mean initial body mass index (BMI) was 39.3 kg/m(2). No major complications occurred. At a median follow-up point of 49 months (range, 17-80 months), the mean %EWL was 72.3% ± 29.3%. For the 23 patients who reached the 6-year follow-up point, the mean %EWL was 55.9% ± 25.55%. The mean BAROS score was 6.5 ± 2.1, and a "good" to "excellent" score was observed for 75 patients (90.4%). In the comparison of patients with a %EWL greater than 50% and those with a %EWL of 50% or less, the SF-36 scores were statistically different only for "physical functioning" and "general health perception." The mean FTS was 23.8, and 95.2% of the patients described their food tolerance as acceptable to excellent.ConclusionLaparoscopic sleeve gastrectomy is a safe and effective bariatric procedure, although a tendency for weight regain is noted after 5 years of follow-up evaluation. Resolution of comorbidity is comparable with that reported in the literature. The LSG procedure results in good to excellent health-related QoL. Food tolerance is lower for patients after LSG than for nonobese patients who had no surgery, but 95.2% described food tolerance as acceptable to excellent.
