Intracorporeal hand-sewn anastomosis between the sigmoid colon and rectum. The intestinal tube was disconnected and closed with a linear cutting occlude at 10 cm from the proximal end of the tumor (A). Electric scissors were used to cut the rectum 2 cm away from the distal end of the tumor (B). The specimen was taken out through the anus (C). Full-thickness continuous suture of the posterior wall (D). Then, the anterior wall was continuously sutured (E). Interrupted seromuscular sutures were placed for the junction of the front and rear walls (F and G). It was checked and ensured that the blood supply of the anastomotic stoma was good and the anastomosis was satisfactory (H and I)
