    Abstract:
    BACKGROUND/AIMS: Capsule endoscopy (CE) is highly sensitive to detect the bleeding source in patients with obscure gastrointestinal bleeding compared with intraoperative enteroscopy (IOE). Long-term follow-up information of patients undergoing CE and IOE for investigation and treatment of chronic gastrointestinal bleeding is lacking. METHODOLOGY: 50 patients with obscure gastrointestinal bleeding underwent CE and IOE. Follow-up data of 47 patients (30 men, 17 women, mean age 60.9 +/- 16.8 years) were available (3 patients lost in follow-up). Clinical outcome was assessed with a standardized patient questionnaire and personal communication with referring physicians. RESULTS: Bleeding sources were detected and effective treated during intraoperative enteroscopy (argon plasma coagulation or surgical resection) in 34 patients [(angiodysplasias (n = 22), ulcers (n = 5), malignant tumors (n = 3), Meckel's diverticulum (n = 1), jejunal varices (n = 1), bleeding ileum diverticulosis (n = 1), hyperplastic polyp (n = 1)]. Mean follow-up was 346.3 days (range 253-814 days). Clinical signs of recurrent gastrointestinal bleeding occurred in 12 of 47 patients (25.5%) [positive fecal occult blood test (n = 2), anemia (n = 2), melena (n = 3), hematochezia (= 5)]. In 3 patients (6.4%) no further therapy was necessary, 9 patients (19.1%) needed blood transfusions (range 2-62 units), endoscopic or surgical interventions to control rebleeding. CONCLUSIONS: The results of the present study support the proposal that capsule endoscopy could be used as the first-choice investigation in patients with obscure gastrointestinal bleeding.
