Objective To systematically review the diagnostic value of capsule endoscopy and enteroscopy in small intestinal diseases.Methods PubMed, The Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were electronically searched to collect studies on the diagnosis of intestinal diseases by capsule endoscopy and enteroscopy from inception to August 31st, 2020. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Meta-analysis was then performed by using RevMan 5.3 and Meta-DiSc software.Results A total of 20 studies were included. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for capsule endoscopy were 0.86 (95%CI 0.83 to 0.87), 0.81 (95%CI 0.78 to 0.84), 117.07 (95%CI 37.98 to 360.92), 7.20 (95%CI 2.81 to 18.45), 0.11 (95%CI 0.06 to 0.21), and those for enteroscopy were 0.89 (95%CI 0.87 to 0.90), 0.91 (95%CI 0.89 to 0.93), 196.99 (95%CI 72.63 to 534.26), 13.26 (95%CI 5.00 to 35.14), 0.12 (95%CI 0.07 to 0.21). The areas under the working characteristic curve (SROC) of capsule endoscopy and enteroscopy were 0.9692 and 0.9783, respectively.Conclusions Both capsule endoscopy and enteroscopy have high specificity and sensitivity in the diagnosis of small intestinal diseases, and enteroscopy has higher clinical value in the diagnosis of some small intestinal diseases than capsule endoscopy. Due to limited quantity and quality of the included studies, the above conclusions are required to be verified by more high-quality studies.
