Technic of resection of mesenteric tumors

In the resection of mesenteric tumors or primary malignant lesions of the small bowel, exposure of the superior mesenteric vessels is important. This is the necessary criterion of resectability and the condition of obtaining maximal margins in the lymphatic drainage area. It also helps avoid unnecessary sacrifice of branches and tributaries to the superior mesenteric vessels from uninvolved portions of the bowel.
