A Gastroendoscopic Study of Chronic Gastritis

Abstract

A progress has been made on the study of chronic gastritis by means of gastrocamera in Japan. It has been noted, however that gastrocamera findings are not necessarily in accord with histological findings.
To make diagnosis more acculate through gastrocamera, author has studied on some factors assured to cause such incompatibility.
1. Adherent mucus, i. e. one of characteristic features of gastrocamera finding on superficial gastritis, and swallowed saliva and airbubbles are often confused on the clinical observation. Preadministration of 2 ml. of di-methylpolisiloxan drops was successful to make saliva and air-bubbles diaapear through the while.
From the fact that no adherent mucus was found on fresh excised stomach specimens in this study, it proves inconclusive sign in gastrocamera diagnosis of superficial gastritis.
2. When 20mg. of Buscopan Complex was intravenously preadministered to the patients previously diagnosed as “spastic stomach” through gastrocamera, figure of atrophic gastritis was observed among some patients, while normal figure of gastric mucous membrane was found in other patients.
It was established, accordingly, that diagnosis of atrophic gastritis would be influenced by degrees of elongation of stomach-wall.
3. Hypertrophic gastritis diagnosed through gastroscopic and/or gastrocamera examination is not necessary conform to findings through histological examination. Then author names the former as “endoscopic hypertrophoid change”, in order to distinguish from the latter.
Before the gastrocamera examination, 20 to 40 mg. of Buscopan Complex was preaddministered te the patients, previously diagnosed as “endoscopic hypertrophoid change”. The result was that figure of atrophic gastritis was observed among some patients, while normal figure was also found others. None of “endoscopic hypertrophoid change” was observed on excised stomach specimens of the patients.
It is assumed that “endoscopic hypertrophoid change” is composed confusedly of the hypertonic state of smoothmuscles in T. muscularis mucosa and T. muscularis propria of the stomach, and of the rugged figure on hyperplastic gastritis.
