ENDOSCOPIC SURGERY USING A MICROWAVE COAGULATOR

The microwave coagulator is an effective tool in endoscopic surgery. Its powerful hemostatic effect is useful in endoscopic polypectomy, small tumor resection and stenotic segmentotomy. Seven patients were successfully treated by endoscopic surgery using a microwave coagulator. Two patients had a gastric or esophageal tumor and anothem five had postanastomotic narrowing or post-radiation stemotic constriction of the gastrointestinal tract. In this report, the practical procedures of endoscopic surgery using a microwave coagulator were demonstrated in three patients. Excellent results were obtained in all of them. Microwave coagulation in endoscopic surgery is useful and effective, and will assume an important place in surgical therapy.
