Abstract
As the new treatment for the severe stenosing stoma after esophageal replacement, the authors have performed endoscopic incision with electric current of high frequency, since 1972. Under esophagofiberscopic control, a radio-knife with flattend tip (Fig. 2) was attached to the stenosing portion through the biopsy channel of the fiberscope, and electric current was supplied very briefly less than 1 second. (Fig1, 3) Postoperative stenosis was improved clinically in 44 out of 48 cases. This method was able to apply to the stenosis which occured after the abdominal, intrathoracic, and retrosternal esophageal replacement, but was not to antethoracic esophaeal replacement. (Fig. 3, 4, 5) This was also applicable to the esophageal transection for varices. (Fig. 6)
