Systematic assessment of massive bleeding of the lower part of the gastrointestinal tract.
A study of 83 patients admitted with massive bleeding in the lower part of the gastrointestinal tract is presented using a diagnostic approach primarily of angiography and colonoscopy with the adjunctive investigations of scintigraphy, small intestine series and computed tomographic scan. The source of bleeding was identified preoperatively in 74 patients. Nine patients had a diagnostic laparotomy and the cause was found in an additional seven. A source was not identified in two patients at exploration and a blind resection was not performed. The two patients have not had recurrent bleeding four and nine years postlaparotomy. The sites of bleeding were colon in 44 patients, small intestine in 24 and the anorectum in 11. Sixty-five patients were treated operatively, two by angiographic embolization and two by endoscopic electrocoagulation. Fourteen patients were managed conservatively. The mortality rate was 10.8 percent and five patients rebled after treatment. We conclude that a thorough systematic assessment of patients with bleeding in the lower part of the gastrointestinal tract is important to localize the site of the hemorrhage. Exploratory laparotomy is the final diagnostic modality, and if a source has not been identified, a blind colonic resection should not be performed.
