Abstract
INTRODUCTION: Like Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy (LSG) has been validated as a bariatric surgery procedure in its own right. However, the few studies of the long-term outcomes of LSG have only featured small patient populations. The objective of the present study was to evaluate weight loss 5 years after LSG and assess the surgical learning curve for this procedure. METHODS: We performed a retrospective, single-center study of a prospective database including all consecutive patients having undergone LSG at Amiens University Medical Center between November 2004 and July 2007. Data (weight, body mass index [BMI], percentage of excess weight loss [EWL], percentage of excess BMI loss, and percentage weight loss [PWL]) were collected during follow-up (particularly after 5 years). RESULTS: The study population comprised 118 patients (100 females [85%]; mean ± SD age, 40 ± 11 years; mean preoperative weight, 131 ± 22 kg; mean preoperative BMI, 47.7 ± 7 kg/m(2)). LSG was performed after failure of gastric banding in 23 cases (19%) and after failure of an intragastric balloon in 1 (0.8%). In all, 95 patients (81%) were analyzed ≥60 months after the LSG (mean follow-up period, 71 ± 9 months). The PWL and EWL were 25 ± 14% and 46 ± 26%, respectively. Eleven patients had undergone a second bariatric operation within 5 years of the LSG. Concerning the 84 patients in whom only LSG was the only operation, the PWL and EWL were 23 ± 14% and 43 ± 25%, respectively. The EWL was >50% in 35 of these 84 patients (42%) and between 25 and 50% in 30 cases (36%). Optimal weight results were achieved after only 28 LSG had been performed, which testifies to a shorter learning curve than for most other bariatric surgery techniques. CONCLUSION: Isolated LSG is a quickly mastered bariatric surgery technique with a short learning curve. It enables a mean PWL of >25% and an EWL of >50% in >40% of cases.
