〔Abstract〕 Objective To analyze the clinical effects of electronic colposcopy in cervical diseases diagnosis. Methods 340 cervical diseases patients admitted to Pingdingshan Maternal and Child Health Hospital from October 2018 to October 2019 were randomly selected as the research objects, All patients were examined by histopathology examination and electronic colposcopy respectively. The examination results obtained by the application of electronic colposcopy in the diagnosis of cervical diseases were analyzed and the patient satisfaction was recorded. Results Among 340 cases of cervical diseases, the detection rate of electronic colposcope on cervical condyloma and cervical cancer was 100.00 %. The diagnostic efficiency of electronic colposcope for cervical cancer and cervical condyloma is higher, but the diagnostic efficiency for cervical inflammation is lower than other cervical diseases. The total satisfaction of electron microscopy was 94.12%. Conclusion Electronic colposcopy for cervical disease diagnosis accuracy is higher, and the patient's acceptance is also higher
