P13.11: Transrectal ultrasound (TRUS) guided biopsy: for women as well as men?

Abstract

Background: Transrectal ultrasound (TRUS) guided biopsy has been used extensively in men, especially for prostate biopsy. This route is less familiar to those performing gynaecologic biopsy but can play a useful role in evaluating pelvic masses in women. Objective: To review our experience in using transrectal ultrasound to guide biopsy of pelvic masses in women through the rectal wall. Methods: We performed an IRB approved chart review of women who had undergone TRUS biopsy at our hospital with respect to indications, patient demographics, lesion characteristics, final diagnosis and effect on management. Results: Eight women had undergone TRUS biopsy. Four had suspected recurrence of prior malignancy (vagina, fallopian tube, endometrium, rectum). Two had multiple prior malignancies (endometrium and breast, endometrium and ovary). One had a large suspicious pelvic mass but was a high surgical risk. One had ascites, cul-de-sac implants and non-specific cytology. Masses ranged from 1.8‐6.6 cm diameter and had solid components. All were successfully biopsied on the first attempt with diagnostic tissue obtained. Biopsy results influenced management in all cases. The procedure was well tolerated and no complications occurred. Conclusions: TRUS guided biopsy is a useful, well tolerated procedure in selected gynaecologic patients.
