Forty-two patients with duodenal ulcer underwent highly selective vagotomy and mucosal antrectomy (HSV+MA) and were followed up for 3 years. Two weeks, 1 year and 3 year after operation, serum gastrim level and gastric emptying capacity were tested. The results show that he postoperative levels of serum gastrin were lower than the preoperative ones, but wih no significant difference (Ｐ＞0.05). Only a few patients had delayed gastric emptying 2 weeks and 1year after operation,but it returned to normal in 3 years .The authors conclude that HSV+MA is a better operative treatment for duodenal ulcer since it can abolish the factors of postoperative ulcer recurence and perserve the functions of the antrum and the pylorus.
