The colonoscope was inserted into the sigmoid colon through the anal aperture. An 18 G needle was inserted into the sigmoid colon percutaneously to the oral cutting point. Through this opening, a 2-0 nylon suture was inserted into the colon. It was retrieved using snare forceps and removed from the anus. The anvil was attached to it, allowing it to be pulled back to the sigmoid colon.
