Ovarian cyst aspiration guided by transvaginal sonography in EWHA Woman's university hospital from 1993 June to 1995 April was performed in 18cases. And the results were as follows.
1) The mean age of patients was 32.2±10.7 years, i-gravida was 8 cases(44.5%). multigravida was 10cases(55.5%), and mean serum CA-125 level before aspiration was 29.5±15.1U/ml.
2) The chief complaints of patients were ; lower abdominal pain in 8 cases(44.5%), post TAH status in 3 cases(16.7%), and vaginal spotting in 2cases(11.0%)
3) The mean diameter of ovarian cyst by transvaginal sonography was 5.9±1.4cm.
4) The mean amount of cystic fluid was 110.8±84.5ml and in 15 cases the fluid was clear yellowish color. In 1 case, that was chocolate color, thick nature and it was compatible with endometrioma.
5) During the follow-up, 3 cases(16.7%) had recurrenece, for the treatment of recurrence, 1 case was by pelviscopy, 1 case was by reaspiration, and 1 case was simply followed-up.
Conclusively, benign ovarian cyst could be managed satisfactorily by transvaginal sonography guided aspiration of cyst. Careful examination using transvaginal sonography and assessment of serum CA-125 is recommended before managing ovarian cyst by transvaginal sonography guided aspiration. And cytologic examination of aspirated fluid is mandatory as well to rule out the existence of malignacy. Therefore, ovarian cyst aspiration guided by transvaginal sonography would be the complete treatment as well as the definite diagnosis.
