Anastomotic Bleeding in Primary Double-stapled Colorectal Anastomosis Relating to the Placement of the Stapler Spike to the Staple Line

What this Trial Is About

This research aims to assess how the position of the stapler spike relative to the rectal staple line affects anastomotic bleeding during colorectal surgery. It focuses on patients undergoing colorectal surgery with primary double-stapled anastomosis, including side-to-end or end-to-end anastomoses. The study involves patients with conditions such as colorectal cancer and diverticulitis. The study compares two groups based on the placement of the stapler spike: one where the spike emerges on the mesenteric side of the linear staple line and another where it comes out on the opposite side. During surgery, each colorectal anastomosis is routinely evaluated by sigmoidoscopy to check for intraluminal bleeding. Postoperative bleeding is also monitored if persistent rectal bleeding occurs within 24 hours after surgery. Participants are closely monitored during and after surgery with evaluations focusing on intraoperative bleeding until the patient leaves the operating room and postoperative bleeding afterward. The research team documents anastomotic orientation and assesses bleeding events to understand the relationship with the stapler spike placement. The total study duration extends to the end of 2028, with detailed observations during and after the surgical procedure.
