Pathophysiological Studies of the Stomach and Duodenum 2. Comparison Between Peptic Ulcer Group and Control Group
It was examined radiographically whether antro-duodenal motility may be influenced by the existence of malrotation of the duodenal loop (MD) or not. Subjects were divided into 97 cases of the gastric ulcer group and 91 cases of the duodenal ulcer group against 94 cases of the control group. Ulcer cases were further subdivided into two stages of open and scar, respectively. The results were as follows : 1. The appearance of MD was noted with higher incidence in the duodenal ulcer group, especially at the open stage. 2. In the duodenal ulcer group, MD was found with higher frequency at the pars superior, while in the other 2 groups, MD was noted more at the pars descendens. 3. In the duodenal ulcer group, acceleration of antro-duodenal motility was noted, in particular being stronger in the MD group than in the normal group. This tendency was found to be stronger at the open stage than at the scar stage.
