Evaluating the Safety and Outcomes of Single-Stapled Colorectal Anastomosis After Planned Left-Sided Colon Surgery

What this Trial Is About

This research aims to assess the safety and practicality of a single-stapled technique SST for colorectal anastomosis in adults undergoing planned left-sided colorectal surgeries, such as sigmoid resection, left hemicolectomy, or partial mesorectal excision, for benign or malignant conditions. It seeks to determine whether SST is linked to a lower rate of anastomotic leakage compared to the conventional double-stapled technique DST, across different surgical approaches including open, laparoscopic, and robot-assisted procedures. Participants in the prospective group will receive colorectal anastomosis using the single-stapled technique during routine clinical care, with data collected on perioperative variables and postoperative complications including leakage within 90 days. A retrospective group who underwent the double-stapled technique from 2023 to 2025 will be identified through medical records to compare outcomes. Both groups are followed to explore differences in leakage rates and postoperative complications. During the study, researchers will collect detailed information on surgical outcomes, including the rate of anastomotic leakage within 90 days, feasibility of the SST during surgery, completeness of anastomotic rings, air leak test results, surgery duration, hospital stay length, readmission rates, complications, mortality, recurrence-free survival up to three years, and stoma-free survival at one and three years. Data is collected prospectively for the SST group and retrospectively for the DST group, aiming to provide multicenter evidence to support future trials.
