Abstract

Background

Sleeve gastrectomy (SG) is gaining popularity and has become the procedure of choice for many bariatric surgeons. Long-term weight loss failure is not uncommon. The preferred revisional procedure for these patients is still under debate.

Objective

The objective of this study was to assess the safety and efficacy of laparoscopic gastric bypass as a revisional surgery for sleeve gastrectomy patients with weight loss failure.

Setting

The study was done at a bariatric surgery center in a university hospital.

Methods

We reviewed our prospectively collected database and identified all patients who underwent conversion of a sleeve gastrectomy to a gastric bypass for weight loss failure. Data on patient demographics, baseline characteristics, and outcomes of bariatric surgery were retrieved.

Results

Twenty-three patients with a mean body mass index (BMI) of 41.6 kg/m2 (range 34.1–50.1 kg/m2) underwent conversion to a gastric bypass. Four patients underwent a gastric band prior to the sleeve gastrectomy, and two patients underwent a re-sleeve gastrectomy prior to conversion to a gastric bypass.

At a mean follow-up of 24 months (range 9–46 months), the average body mass index (BMI) decreased to 33.8 kg/m2 and the excess body mass index loss (EBMIL) was 42.6%. Diabetes, hypertension, dyslipidemia, and obstructive sleep apnea resolved or improved in 44.4, 45.5, 50, and 50% of the patients, respectively. Three patients developed early postop complications (13%), while late complications occurred in four patients (17%).

Conclusion

Converting a sleeve gastrectomy to a gastric bypass for weight loss failure is safe, yet weight loss benefit is limited.
