Severe gastrointestinal bleeding in Crohn's disease

ntroduction: acute gastrointestinal bleeding is rare in Crohn's disease. Methods: we characterized the clinical features and course of such hemorrhage in patients seen at our institution from 1992 to 2000. Results: five patients had gastrointestinal bleeding during Crohn's disease. All patients had a known Crohn's disease, with a mean duration of the disease of 6 years. The source of bleeding was identified in four patients (80%). Endoscopy was, in all patients, the first diagnostic procedure. An Hartmann total colectomy with closure of the rectal stump and ileostomy was performed in three patients, while two patients with ileal massive bleeding were treated conservatively. One patient had a recurrence of bleeding from the small bowel one week later but he didn't required surgical treatment. One patient with pancolic Crohn's disease died on 10th postoperative day because of multior- gan failure and septic complications. Conclusions: gastrointestinal bleeding is rare in Crohn's disease, with a predilection for site of involvement. The preoperative diagnosis of the site of bleeding is not easy, and enteroscopy should be mandatory in such patients. Surgery is required for half of cases and recurrent haemorrhage should be an appropriate indication for surgery
