The average length of the large intestine is 135-150 cm. Ascending and descending segments of the colon are fixed to the retroperitoneum. However, the transverse and sigmoid colon are supported by a mesentery. A comprehensive understanding of the small bowel and colonic vascular anatomy is essential for any physician performing a primary lower gastrointestinal procedure for hemorrhage or other conditions.
