Gastroparesis is a chronic gastric motility disorder in which the pathophysiology mimics a postvagotomy state. Pyloroplasty is beginning to emerge as a successful drainage procedure for refractory gastroparesis. Here we report our experience using pyloroplasty in the surgical management of diabetic and nondiabetic gastroparesis. A retrospective study was performed of 46 patients undergoing pyloroplasty for refractory gastroparesis from January 2010 through December 2013. Gastric emptying scintigraphy and the Gastroparesis Cardinal Symptom Index were assessed pre- and postoperatively. Laparoscopic pyloroplasty was performed in 42 patients, open pyloroplasty in three, and one patient was converted from laparoscopic to open pyloroplasty. Studies were repeated during the six to 12 month postoperative interval. The postoperative gastric emptying scintigraphy improved in 90 per cent of patients and normalized in 60 per cent. Postoperative T½ was significantly reduced (P = 0.001) as was four-hour retention (P < 0.001). The Gastroparesis Cardinal Symptom Index showed statistically significant reduction in symptom severity for all nine categories (P < 0.0005) as well as total symptom score (P < 0.005). No patients developed dumping syndrome. Pyloroplasty is a highly effective therapy for refractory gastroparesis, offering significant reduction in symptom severity, improvement in quality of life, and acceleration of gastric emptying.
