[Recurrent peptic ulcer after surgery in Japan--a nationwide questionnaire survey of 57 institutions].

Patients with recurrent peptic ulcer undergoing surgery were reviewed at 57 institutions by the 18th meeting of the Japanese Research Society of Gastric Surgery. The factors involved in recurrence was analyzed in patients fulfilling the following criteria: the minimum follow-up period was over 5 years, the age was over 15 years, tetragastrin-stimulated acid secretion was measured before surgery, and the recurrence was confirmed by endoscopy or upper gastrointestinal radiography. In 632 patients, the recurrence rate of duodenal ulcer was significantly higher than that of gastric ulcer. However, the duodenal ulcer patients undergoing selective vagotomy and antrectomy did not develop recurrence. A significant difference in the recurrence rate was observed between selective vagotomy and antrectomy and the wide gastrectomy or selective proximal vagotomy. By analysis using the Cox proportional hazard model, the risk factors for recurrence of duodenal ulcer were the ulcer stage, the operative procedure, the location of the ulcer, and the age of the patient. Especially, recurrences in patients receiving selective proximal vagotomy depended on the location of the ulcer and the age, but the risk factors for patients undergoing wide gastrectomy were uncertain.
