Core Tip
Core Tip: Many studies tried to identify the factors that may predict the response to pyloric targeted therapies in gastroparesis according to etiology, prevalent symptoms, antroduodenal manometric study and EndoFLIP. Unfortunately, it is still difficult to reach an accurate determination of the optimal candidates for each treatment. Currently, surgical and endoscopic approach has been compared in term of safety and the results seem encouraging for endoscopic method. In this review we summarize indications, side effects and outcome of gastric per-oral endoscopic myotomy compared to surgical pyloroplasty.
