Clinical impact of multidetector computed tomography before double-balloon enteroscopy for obscure gastrointestinal bleeding

Figure 1 Multidetector computed tomography finding of small bowel neoplasm. A: Abdominal multidetector computed tomography performed after colonoscopy. Abundant bowel gas was observed as a contrast to distend the small intestinal lumen. A focal bowel thickening was discovered (arrows); B: Anal route double-balloon endoscopy disclosed ileal lymphoma accounting for the bowel wall thickening.

Figure 2 Multidetector computed tomography finding of small bowel bleeding. A: Multidetector computed tomography disclosed active contrast extravasations in the jejunum (arrow); B: Oral route double-balloon endoscopy disclosed active bleeding angiodysplasia; C: Endoscopic view after control of bleeding.
