Over-the-scope-clipping system for anastomotic leak after colorectal surgery: report of two cases.

An anastomotic leak is one of the major complications following colorectal surgery. Standard treatments for anastomotic leak are total parenteral nutrition or temporary ileostomy. The over-the-scope-clipping (OTSC) system was originally developed to treat intestinal perforation or to close the tissue after natural orifice transluminal endoscopic surgery. Two cases of successful management of an anastomotic leak after colorectal surgery using the OTSC system are reported. One patient avoided a temporary ileostomy. In the other, hospitalization was shortened by the use of the OTSC system. The OTSC system can be a potential option in the management of anastomotic leaks after colorectal surgery.
