Too loose to lose: an investigation into endoscopic anastomotic reduction to reestablish weight loss

Failure of weight loss, regain of weight, or both after laparoscopic Roux-en-Y gastric bypass (RYGB) resulting from lack of restriction has been reported in long-term follow-up studies. Shulman et al1 in this study determine the safety and effectiveness of reestablishing the restrictive component of the operation by reducing the outlet of the gastrojejunal anastomosis using an endoscopic approach.
