For the dilation of the anastomotic stoma after esophageal replacement, the new dilator was deviced. The distal part of this dilator was movable up to 60° with the manipulation of the proximal end. The dilator was made of the spiral wire and had some flexibility and strongness enough to dilate the cicatrical stenosis. The manipulation of the dilator was taken under the fluoroscopic examination. It was not combined with esophagoscopy. Often the stoma was not straight to axis of the esophagus. Manipulating the distal part of the dilator to fit the anastomotic stoma, then the dilator was passed through the anastomotic stoma.
To dilate the severe stricture, the electric-coagulator was used. Under observation by the esophagofiberscope, the small sized electric-coagulator was fitted to the stenosing portion through the biopsy channel of the fiberscope. After this the dilator was used to maintain the enlarged size.
