OC235: Evaluation clinical results of ultrasound-guided aspiration and coagulation therapy for pelvic cysts by ethanol in short time

To evaluate the clinical results of retaining ethanol and without retaining ethanol in cystic cavity after ultrasound-guided aspiration and ethanol coagulation therapy for women pelvic cysts. 188 pelvic cystic lesions in 182 patients were treated by ultrasound-guided aspiration and ethanol coagulation. Cysts were punctured by percutaneous way or through fornix way under ultrasound-guided and then cystic content was aspirated, ethanol was injected into the cystic cavity in the amount of 1/2 or 1/3 of the content. 3 minutes late, the ethanol was aspirated completely. After the coagulation was repeated one time. 3 ml to 10 ml ethanol were retained in part of cystic cavity or was drown completely randomly. The patient follow up started after treatment and continued until 24 months later. Of 188 cystic lesions, 30 were parovarian cysts, 45 were ovarian cysts, 74 were endometriosis cysts, 33 were encapsulated cysts, 1 was hydrosalpinx, 4 pelvic abscess and 1 luteinic cysts. The ethanol was maintained in 24 lesions and. was drown completely in 158 lesions and 6 lesions were not coagulated by ethanol. The rate of cysts completely disappear was 98% after treatment. During the follow-up period of time 10 patients underwent recurrence. Of the 10 patients 6 with endometriosis cysts, 3 with encapsulated cysts and 1 with parovarian cyst and 3 in ethanol retained group and 7 in ethanol unretained group. There was no statistical significance between two groups' recurrence rate. The main complication was abdomen pain. The pain was taken placed during the ethanol rejection or the puncture needle was drawn after the therapy finish. Ultrasound-guided aspiration and large doses ethanol coagulation for short time was effective and convenient for treatment pelvic cystic lesions. It is worthy of advocate for using in pelvic benign cysts management.
