“…VEof the colon is a well-recognized acquired lesion that maybecome the source of hemorrhage in the lower GI tract in the elderly (9). A Japanese study reported that sporadic VEwas noted in 3% of 430 patients (average age 71 yr) without liver cirrhosis, which was significantly older than the patients (average age 54 yr) without VE.…”

Portal hypertensive colopathy (PHC) is a newclinical entity in patients with liver cirrhosis. In this study, colonoscopic findings and clinical features including upper gastrointestinal endoscopy and hepatic hemodynamics were prospectively investigated among 35 PH patients with a hepatic venous pressure gradient (HVPG) of greater than 12 mmHgdue to chronic liver diseases. Colonoscopy was also performed in 100 patients without liver disease as non-PH controls. The colonoscopy revealed vascular ectasias, vascular irregularity, vascular dilatation, solitary red spots, diffuse red spots, and hemorrhoids in 26, 32, 30, 25, 10 and 25, respectively, of35 PH patients compared to 3, 7, 3, ll, 0 and 19, respectively, in controls. PHC was endoscopically diagnosed in 27 of 35 PHpatients according to our criteria. These patients with PHCwere more frequently associated with esophageal varices and portal hypertensive gastropathy, and had higher HVPG than PHpatients without PHC. Portal hypertension is an important factor in the etiology of PHC. (Internal Medicine 34: 153-157, 1995)

“…Life-threatening GI bleeding can be avoided by prompt angiography and the per formance of hemicolectomy (usually the right colon) when the bleeding lesion is identified [7,21], The structure of the lesions makes it unlikely that permanent, good results will be achieved by selective infusion of vasocon strictors. Moreover, between 5 and 37% of patients continue to bleed following resection of angiographically identified lesions [16].…”

“…Approximately 50% of patients with angiodysplasias have a history or clinical diagnosis of cardiac disease, and 15-25 % have aortic stenosis, but the relationship between the lesions remains unclear. However, the low perfusion pressure seen with aortic stenosis may lead to mucosal anoxia and become a fac tor in producing bleeding episodes in patients who also have angiodysplasias [20][21][22].…”

“…Undiagnosable bleeding creates a 'sur geon's nightmare', when the GI tract is filled with blood, but the source of bleeding at the time of laparotomy can not be demonstrated. Thus, justifiably, this enigmatic malady is also called ' Emperor's-clothes syndrome', be cause the endoscopist cannot identify the lesions, the surgeon finds nothing at operation, and often the pathol ogist finds nothing as well [15].…”
