Abstract
Recently endoscopic treatment is applied to gastrointestinal bleeding, polypoid lesions and cancers. Present paper reports the results of endoscopic microwave therapy from January 1983, using Microtaze Model HS-15M (HEIWA El. CO.). It was performed in 20 cases : 8 cases of a polyp, 5 cases of gastric bleeding, 3 cases of a gastric adenoma and 4 cases of an early gastric cancer. The patients of early gastric cancer were all that refused surgical operation. The microwave tissue coagulation was performed with 30 watt for 10-v20 seconds. In a case of arterial bleeding and four cases of bleeding from the ulcer margin were successfully treated. Polyps, adenomas and cancers were disappeared completely after the therapy. The ulcer scar was observed for three to four weeks. In early cancers and adenomas, biopsy materials were taken from this scar on several occasions and no atypical cells were found until the present time, including a case which has been followed up for eighteen months. It is concluded the endoscopic microwave tissue coagulations is a new technic that can be performed easily and safely.
