“…Seven studies only evaluated the DY of CTE ( n = 294), seven studies compared CTE with CE ( n = 279), two studies compared CTE with double‐balloon enteroscopy (DBE) ( n = 63) and three studies compared CTE with mesenteric digital subtraction angiography (DSA) ( n = 49) . Seven trials were performed in Asia, five in the United States and six in Europe . Consensus was achieved among the independent reviewers regarding decisions on study inclusion in the analysis.…”

“…Due to the introduction of CTE, dramatic refinements of CT technology in evaluating OGIB have occurred. Moreover, studies reported that small‐bowel vascular malformations, tumours and inflammatory bowel diseases have all been detected with this technique . Nevertheless, the sample size of these trials was small.…”

The objective of this article is to provide a comprehensive and update overview of clinical application of CT enterography (CTE) in the evaluation of obscure gastrointestinal bleeding (OGIB). We performed a systematic review of relevant literatures in PubMed, EMBASE and The Cochrane Library and pooled the yield of CTE and the incremental yield (IY) of CTE over an alternate modality. A total of 18 studies (n = 660) reported the yield of CTE in evaluating OGIB and the pooled yield was 40% (95% confidence interval (CI): 33-49%). Seven studies (n = 279) compared the yield of CTE with capsule endoscopy (CE). The yield for CTE and CE for all findings was 34% and 53%, respectively (IY = -19%, 95% CI = -34% to -4%). When considering the types of identified lesions, the yield was significantly different for vascular and inflammatory lesions but not significantly different for neoplastic or other lesions. Two studies (n = 63) compared the yield of CTE with double-balloon enteroscopy (DBE). The yield for CTE and DBE was 38% and 78%, respectively (IY = -40%, 95% CI = -55% to -25%). Three studies (n = 49) compared the yield of CTE with digital subtraction angiography. The yield for CTE and digital subtraction angiography was 64% and 60%, respectively (IY = 4%, 95% CI = -40% to 47%). CTE is an excellent diagnostic tool in patients with OGIB. It may play a complementary role to CE and can be used as a triage tool prior to DBE in evaluating OGIB.
