Sigmoid Colectomy

Sigmoid colectomy (sigmoidectomy) is the removal of the sigmoid colon for any benign or malignant condition. Indications include diverticulitis, volvulus, rectal prolapse, trauma, or malignancy. The procedure can be performed with either an open or minimally invasive approach depending on patient factors and surgeon experience. No matter which technique is chosen, the principles of a sigmoidectomy include ligation of the inferior mesenteric artery, identification and preservation of the left ureter, proximal and distal divisions of the colon and rectum, respectively, at healthy, well-vascularized locations, and preferably, anastomosis to restore intestinal continuity.
