Obscure Gastrointestinal Bleeding: Preoperative CT-guided Percutaneous Needle Localization of the Bleeding Small Bowel Segment

A 57-year-old woman presented with obscure gastrointestinal bleeding. Double balloon enteroscopy, angiography, and surgery including intraoperative enteroscopy failed to identify the bleeding site. Multidetector computed tomography (CT) depicted active bleeding of a small bowel segment. The bleeding segment was localized by CT-guided percutaneous needle insertion and subsequently removed surgically.
