All patients received follow-up endoscopic examinations 6 wk after treatment. When the ulcer(s) were noted to be healed, two biopsies were taken from the ulcer scar for histological study of gastric metaplasia, and 4 biopsies were taken from antrum for Helicobacter pylori(H pylori) study. Out of these cases,44 received further follow-up endoscopic examinations after 3, 6 and 12 mo respectively for studying the recurrence rate of duodenal ulcers. The correlation among ulcer recurrence, degree of gastric metaplasia of regenerating mucosa, bulbar deformity, and colonization of Hpylori in the stomach was then studied.RESULTS: The results showed that there was a strong correlation between the deformity of duodenal bulb and the degree of gastric metaplasia of regenerating duodenal mucosa. The recurrence rate of duodenal ulcer had a significant difference between patients with and without Hpyloricolonization in the stomach (P＜0.001). The greater the degree of gastric metaplasia of duodenal regenerating mucosa, the higher the recurrence rate of duodenal ulcer (P= 0.021). The more deformed the duodenal bulb, the higher the incidence of recurrence of duodenal ulcer (P = 0.03).CONCLUSION: There is a correlation among deformity of duodenal bulb, gastric metaplasia of duodenal regenerating mucosa and recurrence of duodenal ulcer.A more severely deformed duodenal bulb is closely related to a greater extent of gastric metaplasia. Both factors contribute to the recurrence of duodenal ulcer.展开更多
