Prospective Blinded Comparison of Computed Tomographic Enterography and Small Bowel Endoscopy in Obscure Gastrointestinal Bleeding.
HEPATO-GASTROENTEROLOGY(2014)
Abstract
Background/Aims: This study investigated the value of computed tomographic enterography with new techniques, such as multi-planar reformation, curved planar reformation, and blood vessel reformation technique, in evaluation of obscure gastrointestinal bleeding by comparing computed tomographic enterography and small bowel endoscopy. Methodology: We retrospectively evaluated 30 patients with pathologically proven obscure gastrointestinal bleeding. Patients with acute gastrointestinal bleeding were excluded. All patients successfully underwent computed tomographic enterography and small bowel endoscopy at Yantai Yuhuangding Hospital. Results of both methods in the same patient were compared with pathologic biopsy results from clinical operations or endoscopy. Results: Among the 30 patients retrospectively examined by computed tomographic enterography and small bowel endoscopy, the clinical diagnostic accuracy of the two methods was 70% (21/30) and 80% (24/30), respectively. Computed tomographic enterography and small bowel endoscopy showed no statistical difference in the diagnosis of obscure gastrointestinal bleeding (P = 0.37). Conclusions: Computed tomographic enterography can supplement or partly replace small bowel endoscopy in the diagnosis of obscure gastrointestinal bleeding. Computed tomographic enterography not only costs patients less and causes them less suffering, but is also technically easy to perform.
