Background

Vertical sleeve gastrectomy (VSG) is one of the most widely performed procedures in metabolic and bariatric surgery. However, some experience weight recurrence due to sleeve dilation or insufficient primary gastric pouch reduction. Resleeve gastrectomy (ReSG) has been shown to be an effective revisional procedure in achieving sufficient weight loss results. The purpose of this study is to assess weight loss from pre-VSG up to 3 years post- ReSG to provide a comprehensive understanding of weight loss maintenance.

Methods

A retrospective review of patients who underwent a ReSG at a single center from 2017-2022 was performed. Exclusion criteria included those with Roux-en-Y gastric bypass to ReSG, ReSG after duodenal switch (DS), or VSG to ReSG to DS in under 1 year.

Results

Forty-seven patients (79% female, 45.7 years of age) underwent ReSG with an average weight of 266.4 lbs and BMI of 43.6 kg/m2 (Table 1). The average weight at 1, 2, and 3 years postoperative were 212.8 lbs, 201.0 lbs, and 214.5 lbs, respectively (Figure 1). The average BMI at 1, 2, and 3 years postoperative was reduced to 34.7 kg/m2, 31.1 kg/m2, and 34.6 kg/m2, respectively. There was a significant difference in weight (p = 0.017) and BMI (p = 0.021) at 1 year postoperative compared to lowest post-VSG. The 30-day complication rate was 8.5% (n=4).

Conclusions

ReSG demonstrated significant short-intermediate-term weight loss as a revision for weight recurrence after VSG.
