title: Gastric motility and emptying following parietal cell vagotomy and selective gastric vagotomy. Experimental investigation.
abstract: After parietal cell vagotomy in dogs antral motility and gastric emptying time is unaffected. Addition of a drainage procedure changed the motility considerably by decreasing the force of contractions and diminishing the number of peridtaltic waves. After cutting the antral nerves complete atony occurred, but emptying rate was unaltered as the contrast meal passed passively through the anastomosis. Selective gastric vagotomy without drainage caused atony and significantly prolonged emptying time.
