Impact of powered circular stapler on anastomotic leak after anastomosis to the rectum: a propensity score matched study.

Purpose: The aim of the present study is to assess the impact of Echelon Circular powered stapler (PCS) on left-sided colorectal anastomotic leaks and to compare results to conventional circular staplers (CCS).

Methods: A single center cohort study was carried out on 552 consecutive patients, who underwent laparoscopic colorectal resection and anastomosis to the rectum between December 2017 and September 2022. Patients who underwent powered circular anastomosis to the rectum were matched to those who had a conventional stapled anastomosis using a propensity score matching.
