Outcomes of surgical intervention for refractory gastroparesis: a systematic review

Published outcomes of GES, pyloric surgery, and GTx for refractory GP are compared. Pyloromyotomy/pyloroplasty improves patient response greater than with GES. Weighing by number of studies, pyloric surgery improves nausea and abdominal pain greater than GES. For GES, vomiting is more likely to improve than abdominal pain. Weighing by number of patients, pyloric surgery and GTx improved vomiting compared to GES.
