Abstract: Objective To solve the problem of highly misdiagnosis and recurrence.Methods 359 patients with cervical erosion were diagnosed and treated with hysteroscopy.Results The diagnostic ratio of cervical polyp with gross observation was 19.2%(69/359),whereas the value was 50.7%(182/359) by hysteroscopy.Cervical polyp could be found easily by hysteroscopy compared with gross observation.Diagnostic accuracy was improved.Polyp pedicle with superficial muscularis was removed directly under hysteroscopy and the recurrence rate was 1.1%(2/182) in a year which decreased significantly. The recurrence rate was 23.8% in three months by routine polypectomy.Conclusion Hysteroscopy is an effective method for diagnosis and treatment of cervical polyp.
