BLANCO-VELA, Claudia Isabel et al. Guide to endoscopic management and treatment of low digestive tract hemorrhage. Endoscopia [online]. 2019, vol.31, n.1, pp.4-29.  Epub 25-Out-2021. ISSN 2444-6483.  https://doi.org/10.24875/end.m19000002.

Lower gastrointestinal bleeding (LGIB) localizes distal to the ileocecal valve. It presents either as hematochezia, rectal bleeding and melena in some cases. Initial approach must include a complete and detailed clinical and physical exam, laboratory exams in order to determine the severity and source of the hemorrhage. The first step in the treatment of LGIB is to asses and stabilize the patient hemodynamic status and prepare for colonoscopy, which remains the best diagnostic and therapeutic tool. Although LGIB accounts for a significant number of emergencies an hospital admissions, management information usually comes from data obtained and adjusted for upper gastrointestinal bleeding studies. Despite several guidelines have been published, its availability and applicability in our country is limited, therefore, the Asociación Mexicana de Endoscopia Gastrointestinal summoned a group of gastroenterologists, endoscopists and colon and rectum surgeons in order to review, discuss and grade current data on LGIB in order to develop management recommendations for LGIB. The resultant guideline focuses on the etiology, management and follow up of patients presenting LGIB in accordance to international standards and resources available in our country. Guidelines were developed using the Delphi method and evidence was grades using the modified Grading of Recommendations, Assessment, Development and Evaluation System).
