We investigated the effect of mapped antrectomy with gastroduodenostomy on serum gastrin levels in fasting patients and resting lower esophageal sphincter (LES) pressure. Serum gastrin levels in fasting patients were lower in those who had an antrectomy without vagotomy (P <.05) as compared to control subjects or patients with antrectomy and vagotomy. Resting LES pressure was similar in patients and controls and was not affected by the presence or absence of vagotomy. These findings suggest that (1) mapped antrectomy and gastroduodenostomy without vagotomy are followed by a decrease in serum gastrin and (2) resting LES pressure is not affected by mapped antrectomy and a decrease in serum gastrin level.
