The aim of the current study was to compare the diagnostic accuracy of MCE with that of standard gastroscopy for gastric diseases.Patients and methods: A total of 68 patients were enrolled in this self-controlled trial. Patients were evaluated by both MCE and gastroscopy. Gastroscopy was performed 4 – 24 hours after completion of the MCE examination. Results: The positive percent agreement between MCE and gastroscopy was 96.0 %, and the negative percent agreement was 77.8 %. The overall agreement was 91.2 % with a kappa value of 0.765 (P < 0.001). A total of 68 pathological findings were detected, of which 53 were identified by both methods. The MCE and standard gastroscopy missed seven and eight findings, respectively.Conclusions: MCE showed a diagnostic accuracy similar to that of standard gastroscopy. These results suggest that MCE is a promising alternative to gastroscopy for noninvasive screening of gastric diseases.Clinical trial registration number: NCT01903629.
