Double stapling method of anastomosis after esophagectomy with endoscopic stapler to prevent postoperative stricture.

摘要

To prevent stricture of an anastomotic site after operation of esophageal cancer, a new surgical technique, the "double-stapling method," was designed and applied clinically to 29 patients. According to the surgical technique, an automatic suture device for endoscopy was inserted from the side of the lesser curvature of the stomach to the esophageal side after performing end-side anastomosis between the esophagus and the stomach tube using a conventional circular anastomotic device to perform anastomosis between the anterior wall of the esophagus and the posterior wall of the stomach tube. As a result, a conventional anastomotic site, which was a plane (two dimensional), was transformed into a three-dimensional configuration. In the postoperative measurement of the anastomotic site using a measurement forceps, the inner diameter of the site was 8.6+/-3.1 mm in the circular group, while it was 17.2+/-4.5 mm in the DS group, showing a significant difference (p < 0.0001). Minor leakage was observed in three patients as a postoperative complication, but no postoperative hemorrhage occurred.
