Management of Acute Lower Gastrointestinal Bleeding: Principles and Current Practice in the United Kingdom.

Acute lower gastrointestinal bleeding (ALGIB) is a common cause for hospital admission that results in significant morbidity and mortality. The major objectives of all involved in the management of ALGBI patients are to reduce mortality and the need for major surgery. A secondary objective is to prevent unnecessary hospital admission for patients presenting with bleeding that is not life-threatening. The management of ALGBI has evolved over last decade with the changing modalities of diagnostic facilities. On review of the published literature, there is paucity of randomised control trials in relation to the diagnostic tools and management of ALGBI. The aim of this review is to summarise the principles and current methods available for the diagnosis and treatment of ALGIB and based on the available evidence and the current practice in the United Kingdom, outline an algorithm for the management of ALGIB.
