Triangulating stapling vs functional end-to-end stapling for cervical esophagogastric anastomosis after esophagectomy for thoracic esophageal cancer: study protocol for a randomized controlled trial

摘要

BackgroundSeveral studies have reported that the triangulating stapling method decreases the incidence of anastomotic stricture after esophagectomy. Our previous randomized controlled trial, however, could not confirm the superiority of the triangulating stapling (TS) method over the circular stapling (CS) method in terms of postoperative anastomotic stricture rate. Recently, the functional end-to-end stapling (FEES) method for cervical anastomosis after esophagectomy was developed, and lower anastomotic stricture rates with FEES have been reported than for our previously experienced anastomotic methods. To investigate the optimal anastomotic method, we now compare the TS method with the FEES method for cervical anastomosis regarding decrease in anastomotic stricture after esophagectomy for thoracic esophageal cancer.
