Exposure of the Third and Fourth Portions of the Duodenum

  • Jameson L. Chassin


Because the third portion of the duodenum is located behind the superior mesenteric vessels and transverse mesocolon, a direct approach to it would be hazardous. Liberating the right colon and small bowel mesentery from their attachments to the posterior abdominal wall permits the surgeon to elevate the right colon and entire small bowel to a position over the patient’s thorax. This changes the course of the superior mesenteric and middle colic vessels so that they travel directly cephalad, leaving the transverse portion of the duodenum completely exposed.
