[Histologic and cell kinetic findings in stomach ulcer of different healing times].

Abstract

The 3-month healing rate in gastric ulcer patients treated on an outpatient basis and with no H2 blockers is only some 40%. In order to be able to improve therapy at an early stage, prognosis-relevant parameters were searched for also among histological findings. The semiquantitatively evaluated morphological parameters from 62 gastric ulcer patients of a case control study were subjected to a computerized multivariate analysis. Accordingly, at the stage of healing of gastric ulcer, the features 'complete intestinal metaplasia' and 'incomplete intestinal metaplasia' separate with the aid of a non-elementary discriminant function between healing in an appropriate period (3 months) and delayed healing. Histoautoradiographic in vitro examinations of 50 gastric ulcer cases reveal that the mucous membrane around an ulcer healing with delay has a significantly higher cell labeling rate than the gastric mucosa of control persons. The influence of a reflux of bile from the duodenum is discussed, as there is no correlation with the degree of chronic gastritis.
