Abstract
Pyloric motility was observed and analysed by the use of consecutive photography with gastrocamera on 72 patients. Follow-ups made after Schindler's gastrocopic classification (1928) revealed 19.4% of type I, 34.7% type II, 12.5% of their intermediate type and 2.8% of type III. In addition, it was considered quite proper to add another abnormal type of type IV which was recognized in 30.6%.
On comparison of the types of pyloric motility and clinical symptoms, they were found to have parallel relationship. Histologically, it was confirmed that the abnormality of pyloric functions is based on the organic factors of the pyloric ring.
On an understanding that pyloric insufficiency is the pylorus commonly having a certain grade of opening without the picture of complete closure, it was further subdivided into two kinds of simple pyloric insufficiency (P.I, type) and stenotic insufficiency (S.I. type) . And, investigations were made on the relationship between those two types of insufficiency and the types of motility as well as histological findings for the observation of the relationship existing between pyloric insufficiency and pyloric functions.
