- W4309076747 abstract "Lower gastrointestinal bleeding (LGIB), originating mainly in the colon, rectum and anus, occurs most often in older patients (7th decade) with co-morbidity, half of whom have coagulation abnormalities due to anti-coagulant or anti-aggregant therapy. In three cases out of four, bleeding regresses spontaneously but can recur in up to one third of patients. The main causes are diverticular disease, vascular disorders (hemorrhoids, angiodysplasia) and colitis. Ten to 15% of patients present in hypovolemic shock. The main problem is to determine the precise location and etiology of bleeding. First-line steps include correction of hemodynamics, correction of coagulation disorders and transfusion, as necessary. Rectal digital examination allows differentiation between melena and hematochezia. In patients with severe LGIB, upper endoscopy can eliminate upper gastro-intestinal bleeding (UGIB). Computerized tomography (CT) angiography can pinpoint the source. If contrast material extravasates, the therapeutic strategy depends on the cause of bleeding and the general status of the patient: therapeutic colonoscopy, arterial embolization and/or surgery. In the absence of severity criteria (Oakland score≤10), ambulatory colonoscopy should be performed within 14 days. Discontinuation of anticoagulant and/or antiplatet therapy should be discussed case by case according to the original indications." @default.
