Clinical and Experimental Studies on the Hemodynamics of the Pelvic J Pouch in Ileoanal Anastomosis

The purpose of this study was to investigate the efficacy of reserving the ileocolic artery in the pelvic J pouch. Mucosal blood flow of human terminal ileum was measured. It decreased significantly (p

Mucosal blood flow of human terminal ileum was measured. It decreased significantly (p<0.05) with clamping the ileocolic artery and the vein and increased significantly (p<0.01) after declamping. Dogs were used in an experimental model of ileal ischemia. Mucosal blood flow was decreased significant-ly after arterial and venous ligation, and it recovered one week later.

Mucosal blood flow was measured in each group, and histological examinations were performed in sacrificed dogs.
