RESUMEN
AIM: To evaluate the effect of the Valsalva maneuver on ease of the endometrial sampling procedure in cases where the cervix cannot be passed spontaneously. METHODS: A randomized prospective trial was conducted in 84 patients whose cervix could not pass spontaneously with pipelle, and they were randomized for the Valsalva maneuver or tenaculum groups. In 43 of a total of 84 patients, we requested Valsalva maneuver throughout the process to pass the cervical canal, and in 41 patients, we performed tenaculum to pass the cervix. RESULTS: Valsalva and tenaculum groups did not differ in success rates (P = 0.314). There was no difference between the two groups in the history of the disease, past surgery and education (P > 0.05). CONCLUSION: In endometrial sampling procedure with pipelle, when the cervix cannot be passed spontaneously, the transition with the Valsalva maneuver should be tried before using the tenaculum. Thus, a more painful procedure can be avoided and patient satisfaction may increase.
