The lack of response to gastric bypass anti-obesity surgery is often referred to as post-gastric bypass recidivism. Weight regain after Gastric Bypass may very well be related to dietary habits. However, many clinicians and studies, including those conducted and published by Dr. Starpoli, have shown that the stomach pouch and/or outlet made smaller by Gastric Bypass surgery can gradually stretch, making the patient lose the sense of fullness and start to eat more. As a result, patients may regain weight. Read Dr. Starpoli's published work on the success of stomal revision with TORe It has also been shown that open, surgical revision of stomach pouch and/or outlet is undesirable because of the inherent surgical risks and the possibility of anastomotic leakage. This observation has lead to incisionless, endoscopic or endolumenal approaches to reduce the diameter and restore it to its former post-operative size.
