It was made a clamping of the hepatic pedicle in different lapses of time and the morphological features of this intestines were observed. 40 male rats were divided in four groups of 10 animals each. The group S (Sham) was not submitted to ischemia and the groups E1, E2 and E3 suffered ischemia during 10, 20 and 30 minutes respectively. Our results showed macroscopic modifications related to the colour of the intestines in the groups E2 (20') and E3 (30') as well as histopathological changes in the same groups. It was also observed that the larger the lapse of time of clamping of the hepatic pedicle the larger was the splanchnic congestion and in the group 30' detachment of the lining epithelium was observed in the intestinal villi.
