Following removal of the bowel segment, the surgeon may restore continuity of the bowel or create a colostomy. Partial or subtotal colectomy refers to removing a portion of the colon, while total colectomy involves the removal of the entire colon.
The colon is then mobilized from the retroperitoneum. Care is taken to avoid injury to the ureters and duodenum. The surgery then follows the same steps as small bowel resection. However, due to the colon's placement in the retroperitoneum, more dissection is often required to allow for tension free anastomosis. [5] [6]
Attempts at removal can have severe and even lethal effects, such as the rupture of the colon wall by catheter or an acute angle of the fecaloma (stercoral perforation), followed by sepsis. It may also lead to stercoral perforation, a condition characterized by bowel perforation due to pressure necrosis from a fecal mass or fecaloma. [14] [15]
