Purpose: Lower gastrointestinal bleeding (LGIB) is any form of bleeding distal to the Ligament of Treitz. In most cases, acute LGIB is self-limited and resolves spontaneously with conservative management. Methods: Only a minority of approximately 10% is admitted to hospital with signs of massive bleeding and shock requiring resuscitation, urgent evaluation and treatment. Results: Over the past decade, there has been a progressive decrease in upper GI events and a significant increase in lower GI events. Overall, mortality has also decreased, but in-hospital fatality due to upper or lower GI complications have remained constant. The problem is that LGIB can arise from a number of sources and may be a significant cause of hospitalisation and mortality in elderly patients. Conclusions: After initial resuscitation, the diagnosis and treatment of LGIB remains a challenge for acute care surgeons, whereby the identification of the source of bleeding is of utmost importance.
