[Endoscopic resection with local injection of hypertonic saline epinephrine for the treatment of early gastric cancer].
We have developed a new method of endoscopic resection of early gastric carcinomas and other tumors. Characteristics of the new method are summarized as follows. 1. In order to prevent bleeding after endoscopic resection of the tumors, local injection of hypertonic saline epine phrine (HSE) solution was applied to the lesion. Even a depressed lesion like II c type early gastric carcinoma was artificially protruded by local injection of HSE solution. 2. Instead of a single fiberscope, double fiberscopes were employed simultaneously for endoscopic resection of the lesion. 3. Prior to resection of the lesion by high frequency current snare method, incision of the mucosa along the marking line around the lesion performed, enabling the area to be resected precisely. 4. Because tissue damage is mild, resected materials removed are suitable for pathological study. Endoscopic resection was performed on a total of 113 cases in early gastric carcinomas; 103 cases among them (91.2%) were curative resections. Ten cases of the rest underwent surgical gastrectomy for the endoscopic non-curative resections. Rate of five-year survival in 103 cases was 85.2%. Endoscopic resection by our method seems to be effective for the treatment of early gastric carcinomas in any lymph node metastasis and in patients at high surgical risk.
