Vertical banded gastroplasty (VBG) was a popular bariatric operation two decades ago, but it has been discontinued as it necessitates laparotomy in most cases, and there is often a high incidence of weight regain or insufficient weight loss requiring a revisional bariatric procedure.
The aim of the present study was to evaluate one anastomosis gastric bypass (OAGB) as a relatively safe and less demanding solution for the management of weight regain after VBG.
Between February 2014 and September 2017, 42 morbidly obese patients, who had undergone open VBG and suffered from inadequate weight loss or progressive weight regain, were offered laparoscopic OAGB as a revisional surgery. They completed a follow up for at least one year.
All cases were completed laparoscopically. The mean operative time was 166.7?44.6 minutes and the mean hospital stay was 2.2?0.5 days. The mean BMI before revisional surgery was 47.9?6.6 kg/m2, and after one year of follow up it was 29.2?4.9 kg/m2. The mean %EBMIL was 54.3?11.1% at 6 months after surgery and 85.6?16.2% at one year after surgery, with improvement of comorbidities observed in most cases.
Laparoscopic OAGB is a safe revisional bariatric option for failed VBG with very successful results in terms of weight reduction, improvement of comorbidities, and low incidence of major complications.
