title: Massive lower intestinal bleeding--a decade of experience.
abstract: BACKGROUND
  Lower gastrointestinal bleeding is defined as hemorrhage orginating distal to the ligament of Treitz. Its diagnosis is difficult, often requiring endoscopy, angiography and isotope scans.
  
  
  METHODS
  All patients with massive lower gastrointestinal bleeding seen in three gastroenterology centers of Armed Forces during an 11 year period between 1988 and 1999 were retrospectively analysed.
  
  
  RESULTS
  A total of 91 patients with massive lower gastro intestinal bleeding were seen during 11 years. The mean age of the patients was 38.9 years and 64 were males. Aetiological diagnosis was: Non-specific ulcers--11, Ileal tuberculosis--8, NSAID enteropathy--8, Enteric fever--7, Meckel's diverticulum--7, Polyps--6, Ulcerative colitis--5, Carcinoma colon--5, Colonic diverticulosis--5, No cause found--5, Polyposis coli--5, Jejunal diverticulae--3, Angiodysplasia colon--3, Radiation colitis--3, Ischaemic colitis--3, Ileal tumor--2, Ileal angiodysplasia--2, Intestinal Lymphoma--2, Bechet's syndrome--1. Bleeding stopped on conservative therapy in 18 patients (including 5 where no diagnosis could be made). Diagnosis was made in 36 patients on fiber-optic colonoscopy done during active bleeding. Remaining patients were subjected to emergency laparotomy and diagnosis was obvious on inspection of abdominal contents in 25 cases. The diagnosis was finally made in remaining 12 cases by intraoperative endoscopic examination through an ileotomy. Four patients died, only one of them due to rebleed after surgery from an additional lesion.
  
  
  CONCLUSIONS
  Compared with experience in Western countries, massive lower gastro-intestinal hemorrhage in India affects younger patients, has different causes and carries a lower mortality. Colonoscopy is useful in making diagnosis during active lower intestinal bleeding in about one-third cases. Exploratory laparotomy and Intra-operative endoscopy are complimentary to above examination and can make the diagnosis in most of the remaining cases.
