Postoperative colon perforation due to the tip of the transanal decompression tube after laparoscopic low anterior resection: A case report. Issue 4 (18th May 2022) - Sato, Kentaro
Abstract: A 66‐year‐old man underwent laparoscopic low anterior resection for rectal cancer. A transanal decompression tube (24Fr Nelaton catheter) was placed laparoscopically during the surgery. Contrast enema on postoperative day 5 showed perforation of the sigmoid colon around the tip of the tube, and emergency laparotomy was performed. Perforation of the posterior sigmoid colon located on the proximal side of the colorectal anastomosis at the level of the promontorium was identified. Closure of the perforation site, lavage drainage, and a diverting loop ileostomy were performed. Although a transanal decompression tube is useful in preventing anastomotic leakage, tube‐related colon perforation should be noted, and controversies about the safety of laparoscopically transanal decompression tube placement should be resolved. Adequate management for tube placement should be discussed.
