Diagnostic Value of Small Bowel Capsule Endoscopy in Patients with Mid-gastrointestinal Bleeding and Follow-up Study / 胃肠病学

ABSTRACT

Background:Small bowel capsule endoscopy(SBCE)has become a first-line procedure for examining small bowel diseases. Aims:To evaluate the diagnostic value of SBCE in patients with mid-gastrointestinal bleeding(MGIB). Methods:MGIB patients who underwent SBCE from Jan. 2012 to Dec. 2014 at the Third People’s Hospital of Bengbu were enrolled. Diagnostic value of SBCE in MGIB was analyzed. Re-bleeding was followed up by outpatient visit and telephone. Results:Forty-four consecutive MGIB patients underwent SBCE procedures,the detection rate was 95. 5% and the positive rate was 65. 9% . Vascular abnormality(37. 9% ),inflammation(31. 0% )and tumor(20. 7% )were the three major etiology in SBCE positive patients. Follow-up results showed that re-bleeding rate in SBCE positive group was significantly higher than in non-positive group(41. 4% vs. 13. 3% ,P < 0. 05). Conclusions:Vascular abnormality is still the most major etiology of MGIB,meanwhile the proportions of inflammation and tumor are increasing. SBCE has a high detection rate and positive rate in initial screening of MGIB,and the risk of re-bleeding in patients with negative SBCE is low.
