Abstract
As an operation for esophageal-gastric varix, we have performed the blocking of blood circulation and stitching of the gastric wall in the upper region of the stomach. Twelve adult male dogs were operated on. Blood flow in the mucosa and serous membrane was measured before and after each operation. As a clinical study, the cases of esophageal-gastric varix hospitalized here were divided into an endoscopic injection sclerotherapy (EIS) group, an esophageal transection group, and a group for our type of operation, and a comparative study was made. In the experiment using adult dogs, the blood flow in the upper part of the gastric body decreased about 1/3 from that before the operation on both the mucosal and the serous membrane sides. The mucosal blood flow remained significantly decreased at about 1/2 the preoperation level for up to 12 weeks after the operation. The decrease was greater than in the lower part of the gastric body. In the present experiment, the blood flow blocking effect of this operation was determined by measuring the blood flow, and the effectiveness, safety and universality of the operation was confirmed by studying clinical cases. It is concluded that this operation is one of the more effective types of operation among the prospective and prophylactic cases for which surgery is indicated.
