  • Title: Histological maturity of healed duodenal ulcers and ulcer recurrence after treatment with colloidal bismuth subcitrate or cimetidine.
    Author: Pan SA, Liao CH, Lien GS, Chen SH.
    Journal: Gastroenterology; 1991 Nov; 101(5):1187-91. PubMed ID: 1936788.
    Abstract:
    The relationship between histological maturity of healed duodenal ulcers and ulcer recurrence after 6 weeks of treatment with colloidal bismuth subcitrate or cimetidine was investigated. There was no significant difference in healing rates between colloidal bismuth subcitrate- and cimetidine-treated patients (85.7% and 71.8%, respectively; P greater than 0.05). Histologically, the regenerating mucosa of healed ulcers was divided into three categories--good, fair, and poor--according to pattern. Sixty percent of healed colloidal bismuth subcitrate-treated and 30.9% of healed cimetidine-treated ulcers had a good pattern; the difference was statistically significant (P = 0.027). The difference in recurrence rates between healed colloidal bismuth subcitrate-treated and healed cimetidine-treated patients was statistically significant at 3 months (3.45% and 20%, respectively; P = 0.044). All recurrent ulcers in both groups had fair or poor patterns of regenerating mucosa. It was concluded that the greater histological maturity of the regenerating mucosa may contribute to the lower recurrence rate in colloidal bismuth subcitrate-treated patients than in cimetidine-treated patients.
