Ultrasonic transvaginal aspiration of endometriotic cysts: an optional line of treatment in selected cases of endometriosis.

Transvaginal ultrasonically guided aspiration of pelvic endometriotic cysts was performed on 21 patients with recurrent endometriosis after previous surgical treatment. Their main complaint was pelvic pain and infertility. Further conservative surgery was considered a contraindication. The symptoms improved markedly following aspiration. During a 12 month follow-up, reaccumulation occurred in only six cases (28.5%) and the improvement in symptoms persisted in the majority of cases. The technique is simple, safe and effective in the treatment of selected cases of endometriosis.
