The association of duodenogastric reflux with dumping and gastric retention.

Gastric emptying of solid and liquid meals together with duodenogastric reflux has been measured in a prospective trial of proximal gastric vagotomy and truncal vagotomy and antrectomy. Three abnormalities of motility associated with postoperative symptoms have been defined. If more than one abnormality was present in an individual there was an 80 per cent incidence of associated symptoms. Proximal gastric vagotomy produced significantly fewer abnormalities of gastro-duodenal motility than did truncal vagotomy and antrectomy.
