Long-term weight loss in laparoscopic sleeve gastrectomy.
Surg Obes Relat Dis. 2017 Oct; 13(10):1676-1681.SO

Abstract

INTRODUCTION

Laparoscopic sleeve gastrectomy (LSG) has become an option as a bariatric surgical technique. There is a lack of long-term results of this procedure in the literature. The aim of this study is to present weight loss results of LSG for up to 7 years of follow-up.

METHODS

A retrospective series of patients who underwent LSG between 2008 and 2011 was examined. The primary endpoint was weight loss: percentage of excess weight loss (%EWL), percentage of total weight loss (%TWL), and body mass index (BMI) were reported. Failure was defined as %EWL<50%. Multivariate analysis for weight loss was performed. The complications rate was reported.

RESULTS

A total of 148 patients met the inclusion criteria; 76.3% were female. Mean preoperative BMI was 36 ± 4 kg/m2. Mean operative time was 89.3 ± 3.2 minutes. Follow-up at 5, 6, and 7 years was 77.7%, 83.3%, and 82.2%, respectively. Mean %EWL and %TWL at 1, 3, 5, and 7 years was 93.2%, 80.7%, 70.6%, and 51.7%, and 27.2%, 23.3%, 20.4%, and 16.3%, respectively. The failure rate was 30.4% at the fifth year and 51.4% at the seventh year. High preoperative BMI was related to worse %EWL (P<0.001) but not to %TWL. Preoperative BMI<35 kg/m2 was associated with better %EWL but not with %TWL (P = 0.003). Four leaks (2.7%) and no mortalities were reported.

CONCLUSIONS

LSG is an acceptable surgical technique for weight loss, but in this series, up to one third of the patients fail at the fifth year and half fail in the seventh year. %EWL is better in patients with BMI<35 kg/m2, but this difference disappears when we express outcomes with %TWL.
