Abstract

We investigated the relationship between histological maturity of healed duodenal ulcer and ulcer recurrence after treatment with omeprazole or cimetidine for 4 weeks. The healing rates, 92.5 and 72.4% in omeprazole-treated and cimetidine-treated groups, respectively, showed no significant difference between groups (P > 0.05). Histologically, the regenerating mucosa of healed ulcer was divided into three categories: good, fair and poor patterns. Of the healed cases, 22 (59.5%) of 37 omeprazole-treated and 12 omeprazole-treated and 12 (28.6%) of 42 cimetidine-treated ulcers achieved a good pattern, showing significant difference between groups (P = 0.01). The recurrence rate at 3 months showed statistically significant difference (P <0.05) between two groups: 5.4% in omeprazole-treated and 23.8% in cimetidine-treated patients. During the period between 3 and 6 months after healing, the difference in recurrence rate between omeprazole-treated and cimetidine-treated groups was statistically not significant (12.5% and 25%, respectively, P > 0.05), though the cumulative recurrence rate at 6 months showed a significant difference between groups (17.6% vs 44.7%, P = 0.027). All the recurrent cases of both groups had a fair or poor pattern of regenerating mucosa. The difference in recurrence rate was statistically significant between the healed ulcers with a good pattern and that with a fair or poor patterns both at 3 months and between 3 and 6 months after healing (P <0.001 in each). We concluded that better histological maturity of regenerating mucosa may contribute to the lower early recurrence in omeprazole-treated cases than in cimetidine-treated cases.
