Abstract
With the cumulative increase in the number of patients undergoing bariatric surgery, postoperative weight regain has become a considerable challenge. Mechanisms for weight regain are not fully understood and the process is likely multifactorial in many cases, including type of surgery, physical activity, psychiatric comorbidities, and patient dietary adherence. Additionally, post-surgical anatomy modification such as larger pouch size and dilation of the gastrojejunal anastomosis (GJA) have been shown to correlate with increased postoperative weight gain. Endoluminal revisions that reduce gastric pouch size and diameter of the GJA may offer an effective and less invasive management strategy for this population.
