Abstract

A total of 31 patients underwent revisional single-anastomosis gastric bypass after initial laparoscopic sleeve gastrectomy.

The mean weight of patients prior to laparoscopic sleeve gastrectomy was 127.5 kg with a mean BMI of 49.0 kg/m.
Patients experienced a mean weight loss of 43.8 kg following the initial procedure.
The average time until patients had revisional surgery was 5.1 years, primarily due to weight regain (86.2%).
Post-revisional surgery, patients showed an excess weight loss of 14.5%, 31.9%, 48.0%, and 58.9% at 2 weeks, 3 months, 6 months, and 1 year, respectively.
A total of 10.3% of patients reported morbidities, which were successfully resolved.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) has become the most performed bariatric procedure as of 2015. However, inadequate weight loss may present the need for revisional procedures.

OBJECTIVES: The objective of this study was to analyze the efficacy of single-anastomosis gastric bypass (SAGB) in attaining successful weight loss following an initial LSG.

METHODS: A retrospective analysis was performed on all patients who underwent LSG at Amiri Hospital, Kuwait from 2008 to 2017. A list was obtained of those who underwent revisional SAGB surgery after initial LSG, and their demographics were analyzed.

RESULTS: A total of 31 patients underwent revisional SAGB bariatric surgery after initial LSG, of which 87.1% were female. Prior to LSG, the mean weight of the patients was 127.5 kg and the mean BMI was 49.0 kg/m. The mean weight loss after initial LSG was 43.8 kg, while the average duration until patients underwent revisional SAGB was 5.1 years. The cause for revision was weight regain (86.2%), inadequate weight loss (10.3%), or the development of a complication (reflux) (6.5%). Prior to undergoing revisional SAGB, the weight and BMI of the patients were 110.9 kg and 42.6 kg/m, respectively. This demonstrated a %excess weight loss of 14.5, 31.9, 48.0, and 58.9% 2 weeks, 3 months, 6 months, and 1-year post-SAGB, respectively. Three (10.3%) morbidities were reported and thereafter successfully resolved. 2 2

CONCLUSION: Revisional SAGB bariatric surgery is a safe and effective method in the short-term basis for the management of inadequate primary LSG.
