Statistical studies on clinical diagnosis of intractable peptic ulcer

Abstract

In order to evaluate the factors influencing a healing process of peptic ulcer, relationships between a period of time required for the healing and each of 26 factors seemingly affecting the healing process were studied in 253 patients with gastric ulcer. The degree of correlation between the parameters was tested by means of Hayashi's quantification type II, principal component analysis and multiple regression analysis.
The factors such as “treatment enviroment” i. e. out-patient or in-patient, age, location and depth of the ulcer, were revealed to have a close relation with the healing process. Among endoscopic findings, degree of the marginal elevation and hemorrhage in surroundings were found to be moreimportant than the others. The age, the location of ulcer and accompanying gastritis were important factors for the healing process in in-patients, whereas the location and the depth of ulcer and the hemorrhage in surroundings were influential in out-patients. These facts suggest that there is a difference in the healing process of ulcer between these groups of patients.
