421. THE STAPLED ANASTOMOSIS IN ESOPHAGECTOMY: NO DIFFERENCES IN LEAKAGE AND STRICTURE-RATES BETWEEN THE 25 MM AND 28 MM CIRCULAR STAPLER

Abstract For patients undergoing an Ivor Lewis esophagectomy with a circular stapled anastomosis, the optimal diameter of used stapler to restore continuity is unknown. The aim this study was compare 25 mm versus 28 esophagogastric anastomosis after esophagectomy, focusing on anastomotic insufficiency and post- operative strictures. Between February 2008 June 2019, 349 consecutive underwent gastric conduit reconstruction anastomosis. Patient characteristics postoperative results, such as rates, stricture time rate, number dilatations, were recorded in prospective database analyzed. In 222 (64%), used. There no differences baseline characteristics. Anastomotic rates comparable between (12%) groups (11%) (p = 0.751). strictures (14%) 0.863). Within strictures, median 2 dilatations observed each group 0.573) without first diagnosis 0.412). esophagectomy. Both can be safely create
