Both physiologically and anatomically, the right half of the colon lends itself admirably to direct surgical procedures with very little general disturbance to the patient. Developmentally, the right half of the colon differs from the left, and certain anatomic relations render its mobilization comparatively simple; its sacrifice not incompatible with comfortable existence, and its removal less likely to be followed by unpleasant complications and malignant recurrences. In fetal life, the entire colon begins low in the left side of the abdomen close to the middle line, and then rises progressively, rotating around the superior mesenteric artery as an axis until it reaches the attachment of the splenocolic ligament, which is derived from the omentum, under the diaphragm in the left splenic fossa.
