Total colectomy performed due to large bowel gangrene, from caecum to sigmoid colon.

Total abdominal colectomy is the removal of the large intestine. Traditionally, colectomy is performed via an abdominal incision (laparotomy), though minimally invasive colectomy, by means of laparoscopy, is growing both in scope of indications and popularity. Resection of any part of the colon entails mobilization and ligation of the corresponding blood vessels. Lymphadenectomy is usually performed through excision of the fatty tissue adjacent to these vessels (mesocolon), in operations for colon cancer. When the resection is complete, the surgeon has the option of immediately restoring the bowel, by stitching or stapling together both the cut ends (primary anastomosis), or creating a colostomy.
