Parastomal ileal conduit hemorrhage and portal hypertension.
An analysis of six cases of parastomal ileal conduit hemorrhage in patients with portal hypertension is presented. The presence of coexisting esophageal varices, documented in only one of six cases (17%), suggest preferential retrograde portal flow through mesenteric venous (as opposed to coronary-azygos) collateral channels. Venous phase mesenteric angiography offers the best diagnostic specificity and provides inferential evidence regarding overall liver blood flow. Operative therapy should be based on assessment and understanding of the splanchnic circulatory derangements which accompany intrahepatic portal obstruction.
