Information on the physiology of the blood flow to the bowel in man is limiited, due to the impossibility of routine sampling of the portal blood stream. Data obtained from animal studies have shown widely variable results, owing to differences in anesthetic and surgical technique, and to the use of flow measuring devices that are not comparable (1). Evidence indicates, however, that the mesenteric circulation can be characterized as a system rich in anastomotic networks, with low resistance, high flow, and a moderate atrioventricular extraction at rest (about 4.9 vol/100 ml) (2). The increasing clinical interest in this area is
