Performing an open right colectomy requires a midline incision, after which the small bowel is retracted to the left side and covered with a wet sponge. The ileocolic vessel is dissected free at the inferior edge of the duodenum. The white line of Toldt is mobilized from the terminal ileum up to and including the hepatic flexure. The right branch of the middle colic artery is divided, and the ileum and transverse colon are brought out of the wound. The anastomosis is performed as described above.
