RESUMO
OBJECTIVE: To determine the safety and efficacy of ultrasonic surgical aspiration (USA) in the treatment of vaginal intraepithelial neoplasia (VAIN). METHODS: Using the ICD code for VAIN, all patients who underwent USA were evaluated. Patient demographics, clinicopathologic data, and follow-up outcomes were abstracted from the medical records. RESULTS: Ninety-two patients underwent USA for VAIN. No surgical complications or postoperative scarring were recorded, and all patients were followed without further therapy after the procedure. Pathologic evaluation of the degree of VAIN in the aspirate obtained at the time of USA correlated with the preoperative biopsy results in all cases. With a median follow-up period of 4.5 years, the overall recurrence rate was 19.6%. The recurrence rate for high grade VAIN was significantly greater than that for low grade VAIN (32.3% vs 13.1%, P=0.044). CONCLUSION: Ultrasonic surgical aspiration is a safe and effective surgical option for VAIN, providing a histologic sample with minimal invasiveness.
