Haematochezia is the passage of fresh blood through the anus, usually in or with stools (contrast with melena).[1] The term is from Greek αἷμα ("blood") and χέζειν ("to defaecate"). Hematochezia is commonly associated with lower gastrointestinal bleeding, but may also occur from a brisk upper gastrointestinal bleed. The difference between hematochezia and rectorrhagia is that, in the latter, rectal bleeding is not associated with defecation; instead, it is associated with expulsion of fresh bright red blood without stools.[2] The phrase bright red blood per rectum is associated with hematochezia and rectorrhagia.
