LGIB - high risk features

Q: A non-tender abdomen is considered a high risk feature in presumed acute lower gastro-intestinal (GI) bleeding.

A) True
B) False


Answer: A

Some risk factors in presumed acute lower GI bleeding are expected but few are quiet unusual like a non-tender abdomen and no diarrhea.  Other known risk factors in acute lower GI bleed are significant hypotension, other comorbidities, old age, diverticulosis, angiodysplasia, aspirin use, coagulopathy, hypoalbuminemia, elevated blood urea nitrogen (BUN) level and leucocytosis.
