Revisional sleeve gastrectomy after failed gastric clipping for obesity: Report of two cases and review of literature.

Laparoscopic gastric clipping (LGC) is one of the bariatric surgeries that are minimally invasive and demonstrates effectiveness in reducing body weight for obese patients. However, the patients may later regain body weight and other treatments may be needed. In this case report, two cases with obesity received LGC, which initially reduced their weight. However, they presented with a progressive regaining of body weight a few years after the surgery. Thus, revisional sleeve gastrectomy was conducted in an institute to control their weight regain. Postoperative courses were smooth, and there was no complication. Thus, laparoscopic removal of gastric clipping accompanied with revisional sleeve gastrectomy is technically feasible for the patients.
