“…Algunos autores refieren tener un éxito del 74 14 -82% 18 en el diagnóstico identificando el origen de la hemorragia. Además, es imprescindible su realización para descartar la presencia de neoplasias en todos los pacientes con hemorragia 9,19 . La mayoría de autores recomienda la realización de una purga mediante lavado anterógrado al menos durante las 2 h previas a la realización de la colonoscopia 14,15,17 .…”

“…Exceptuando de nuevo a las ciudades asiáticas donde la diverticulosis predomina en el colon derecho (74%) 9,24 , la diverticulosis en países occidentales ocurre mayoritariamente en el colon distal (85%) y solo el 15% en colon derecho. A pesar de esto, la hemorragia diverticular suele ocurrir más frecuentemente en colon proximal al ángulo esplénico y colon derecho 6,9,25 . Sin embargo, en nuestra serie la hemorragia se ha presentado en colon sigmoide (67%) o colon sigmoide más descendente (33%).…”

“…Other sources of gastrointestinal hemorrhage: The UGI tract should always be considered in patients presenting with bright red blood per rectum. Approximately 10% to 15% of cases of acute rectal bleeding have a UGI source (104). If an upper endoscopy and an evaluation of the colon are both negative, the small bowel should also be considered as a possible source of bleeding.…”

Acute lower gastrointestinal (LGI) bleeding is typically caused by vascular malformations, diverticuli and neoplasia. Although endoscopic evaluation of the colon is relatively standard in stable patients with LGI bleeding, those with significant ongoing hemorrhage are often more difficult to evaluate endoscopically. Other investigative techniques such as nuclear scintigraphy, angiography and surgical exploration have been commonly used in unstable patients with LGI bleeding when the exact site is unknown. These investigative techniques have had variable measures of success. This two-part review evaluates the literature in an attempt to review the optimal investigative approach in patients with LGI hemorrhage, in particular patients who have had significant and ongoing bleeding. Part 1 of this article concentrates on the etiology of LGI hemorrhage, followed in a subsequent article by diagnostic and management strategies. Following the review, a consensus update will be included with guidelines for clinical use.
