[Clinical study and long-term follow-up observations on the effect of PCV and SV+A in the treatment of duodenal ulcer].

From Aug. 1977 to June 1988, vagotomy had been performed in 238 patients with duodenal ulcer (DU). According to the clinical signs and the result of gastric acid secretion test, (GAST) parietal cell vagotomy (PCV) and selective vagotomy plus antrectomy (SV+A) were performed in 100 and 138 cases respectively. The patients were followed up for 1 to 10 years. 96% and 97% of them belonged to Visick grade I and II respectively. The recurrence rate was 1.96% in PCV group, while no ulcer recurrence was seen in SV+A group, long-term side effect was rare and the nutritional status was quite good. The follow-up data showed that recurrence rate could be greatly reduced if the mode of vagotomy was selected according to results of GAST.
