Abstract

New guidelines have been produced through collaborative work between the British Society of Gastroenterology (BSG), the Association of Coloproctology of Great Britain and Ireland, the British Society of Interventional Radiology, the Royal College of Radiologists, National Health Service Blood and Transplants and patient representatives. This is the first UK national guidance for lower gastrointestinal bleeding (LGIB). The focus is the in-hospital management of adult patients presenting with acute LGIB. LGIB refers to patients presenting with bright or dark red blood per rectum, clots per rectum or blood mixed with stool. We provide a commentary and overview of the key features, with a particular focus on risk assessment, management, investigations, and radiological and endoscopic intervention.
