Objectives The aim of the present study was to determine the efficacy and safety of the ultrasonic surgical aspiration (Sonopet ® ) in the treatment of anogenital intraepithelial neoplasia.
Methods We conducted a retrospective chart review of patients who underwent treatment of anogenital intraepithelial neoplasia between 2011 and 2018 with the ultrasonic surgical aspirator (Sonopet ® ).
Results 256 patients underwent treatment with the ultrasonic surgical aspirator. The most frequent pathologic entities treated were VIN 2 (41.79%) and VAIN 2 (40.62%). Anal disease including both condyloma and anal intraepithelial lesions were found and treated in 10.56% of patients. Overall recurrence for patients treated with Sonopet was 10.54%. For patients previously treated with other modalities such as laser, the recurrence rate was even lower (2.34%). The median time to recurrence was 12.2 months. No surgical complications were recorded, and only minor post-operative complications were reported by patients.
Conclusions The ultrasonic surgical aspiration (Sonopet®) is effective and safe surgical procedure for treatment of anogenital intraepithelial neoplasia. It was effective in both dermal and mucosal pathologies.
