Motility of the residual stomach after subdiaphragmatic proximal gastrectomy was observed with cinefluorographic and photo-optical techniques. Subjects studied were twenty patients with benign and malignant lesions of the upper stomach who have undergone proximal gastrectomy in our department. Results obtained are as follows:<BR>In the group of one third resection of the proximal portion of the stomach gastric peristalsis was restored to normal pattern several weeks after operation.<BR>In the group of one half to two third resection gastric peristalsis was inhibited immediately after operation but was markedly restored to normal five to six months after operation.<BR>In the group of three fourth resection with drainage procedure it was rather hard to find restoration of motility of the residual stomach, and esophageal reflux due to duodenal peristalsis was frequently observed. That is to say, it seems that the more extensively proximal portion of the stomach is resected, the more difficult restoration of gastric peristalsis becomes.<BR>From the results mentioned above it is considered that proximal gastrectomy should be performed only in the case being resected less than one half and other pro-cedures such as interposition should be selected in the case for which further extensive resection is necessary.
