AIM To evaluate diagnostic yields of capsule endoscopy(CE) and/or single-balloon enteroscopy(SBE) in patients with suspected small bowel diseases.METHODS Were trospectively analyzed 700 patients with suspected small bowel diseases from September 2010 to March 2016. CE, SBE, or SBE with prior CE was performed in 401, 353, and 47 patients, respectively. Data from clinical and endoscopy records were collected for analysis. Indications, procedure times, diagnostic yields, and complications were summarized and evaluated.RESULTS The overall diagnostic yield for the CE group was 57.6%. The diagnostic yield of CE in patients with obscure gastroin testinal bleeding(OGIB) was significantly greater than that in patients with no bleeding(70.5% vs 43.8%, P < 0.01). The overall diagnostic yield of SBE was 69.7%. There was no difference in the diagnostic yield of SBE between patients with OGIB and those with no bleeding(72.5% vs 68.9%, P = 0.534). Forty-seven patients underwent CE prior to SBE. Among them, the diagnostic yield of SBE with positive findings on prior CE was 93.3%. In addition, SBE detected two cases with superficial ulcer and erosive lesions in the small bowel, which were missed by CE. However, one case with lymphoma and two with Crohn's disease were not confirmed by SBE. The rate of capsule retention was 2.0%. There were no significant complications during or after SBE examinations.CONCLUSION SBE is a safe and effective technique for diagnosing small bowel diseases. SBE with prior CE seemed to improve the diagnostic yield of small bowel diseases.
