Considerable time is required to separate the blood supply proximally from the site where the ileum is to be divided. Several centimeters of ileum can be denuded of blood supply in preparation for the development of an ileostomy (Figure 9). The blood supply to this portion of the ileum should be divided very carefully, almost one vessel at a time, maintaining the large vascular arcade at some distance from the mesenteric border. A noncrushing vascular-type clamp is applied to the ileal side and a straight Kocher clamp to the cecal side in preparation for the division of the intestine (Figure 10). Most commonly, however, the ileum is divided with a cutting linear stapler (GIA) stapling instrument. The contents of the Kocher clamp can be ligated with heavy silk or absorbable suture to facilitate handling of the right colon (Figure 11).
