ABSTRACT
Splenic flexure colon cancer occurs at a relatively lower rate than colon cancer of other sites. It is also associated with more advanced disease and higher rate of acute obstruction. The splenic flexure receives blood supply from both superior and inferior mesenteric arteries (SMA and IMA), and therefore has lymphatic drainage to both areas. The blood supply is also highly variable, causing difficulties in determining the main feeding vessels and the main direction of lymph drainage. Few studies with limited cases focused on this specific tumor site with respect to the patterns of lymph node spread, especially the main lymph node status and the value of its dissection. The lack of information limits the development of a consensus on the extent of surgical resection and lymphadenectomy. Adequate mobilization of the colon facilitates a sufficient length of bowel resection and the high ligation of feeding arteries from both SMA and IMA. Further evidence on the chnoice of procedures and the extent of lymph node dissection need multicenter collaboration, with the use of modern techniques, including CT 3D reconstruction of the colon and angiography, as well as intraoperative fluorescent real-time imaging of lymph nodes.
