Natural Orifice Specimen Extraction (NOSE) with Single-Stapling Anastomosis for Left Colon Cancer

One of the major criticisms of laparoscopic colectomy is the requirement of an additional mini laparotomy to remove the resected specimen. This may be associated with postoperative pain and wound complications. Therefore, the use of a natural orifice as a delivery route for the specimen extraction without a laparotomy incision can subsequently reduce the risk of wound complications. In this video, we demonstrate the natural orifice specimen extraction procedure with a side-to-end single-stapling colorectal anastomosis.
