RESUMEN
Although most patients presenting with a fibrotic stricture at an esophagocolic or esophagogastric anastomosis respond well to the classical dilation therapy, a number of them do not and are therefore considered to have a condition refractory to the classical method. In these cases, we performed fiberesophagoscopic section and segmentation of the stenosing ring itself, which did not exceed one cm in length, using appropriate equipment such as an electric endoscopic scalpel. Widening of the strictured segment was completed with successive dilations using a Maloney type bougie. Dysphagia disappeared after the endoscopic procedure in 21 (84%) of the 25 patients with stricture of the cervical anastomosis, after esophagocoloplasty or esophagogastroplasty, without any serious complications.
