[Pre- and postoperative manometeric findings in the esophagus in proximal selective vagotomy]

15 patients with duodenal ulcer underwent clinical and manometric studies to assess distal esophageal function before and after proximal selective vagotomy. Position, pressure and function of distal esophageal high pressure zone were not altered by the operation. No rationale has been found for the trend to combine proximal selective vagtomy with antireflux procedures.
