Assessment of upper gastrointestinal bleeding

Upper gastrointestinal bleeding (UGIB) refers to GI blood loss whose origin is proximal to the ligament of Treitz at the duodenojejunal junction. Acute UGIB can manifest in a variety of manners, including haematemesis, coffee-ground emesis, the return of bright red blood through a nasogastric tube, and melaena with or without haemodynamic compromise. Haematochezia (bright red blood per rectum) may rarely occur in patients with an extremely brisk UGIB. [1] Wilcox CM, Alexander LN, Cotsonis G.

UGIB results in more than 300,000 hospital admissions annually in the US, with a mortality of 7% to 10%. [3] Yavorski RT, Wong RK, Maydonovitch C, et al.

Rapid evaluation, haemodynamic resuscitation, and appropriate pharmacological and endoscopic interventions are the cornerstones of therapy.
