RUIZ-CLAVIJO, D. et al. Severe lower gastrointestinal bleeding in a 25-year-old patient. Anales Sis San Navarra [online]. 2012, vol.35, n.3, pp.517-520. ISSN 1137-6627.  https://dx.doi.org/10.4321/S1137-66272012000300023.

Lower gastrointestinal bleeding refers to blood loss originating from a site distal to the ligament of Treitz. The aetiology varies depending on the age of patients. Excluding benign anorectal pathology in children and young people, Meckel´s diverticulum, juvenile polyps and inflammatory bowel disease are the main causes. Meckel´s diverticulum is the most common congenital anomaly of the gastrointestinal tract, being present in about 2% of the general population. Most Meckel´s diverticulum are asymptomatic and are diagnosed incidentally. The risk of complications is 4-6%, with bleeding as one of them.

Palabras clave : Meckel´s diverticulum; Gastrointestinal bleeding; Laparotomy.
