Pylorojejunostomy has been successfully substituted for pyloroplasty when the latter is technically difficult. Heidenhain pouch studies in dogs indicate that acid secretory effects of pylorojejunostomy and pyloroplasty are comparable and similar to those of the control period and superior to those of gastroenterostomy. There is little evidence of regurgitation of intestinal contents into the stomach, and there is considerable evidence of efficient emptying of the stomach following pylorojejunostomy.
