Gestrinone combined with ultrasound-guided aspiration and ethanol injection for treatment of chocolate cyst of ovary

Aim: The aim of this study was to determine clinical performance of gestrinone combined with ultrasound-guided aspiration and ethanol injection in treating chocolate cyst of ovary.

Methods: Sixty-eight patients enrolled in this study were randomly divided into two groups: control group and combination treatment group. In the control group, 34 patients were treated with ultrasound-guided aspiration and ethanol injection. In the combination treatment group, 34 patients received gestrinone p.o. following ultrasound-guided aspiration and ethanol injection.

Results: The recurrence rate of chocolate cyst was 10-fold lower in the combination treatment group (2.94%, 1/34) than in the control group (29.4%, 10/34) at 12 months. The effective rate for reduction of chocolate cyst was significantly higher in the combination treatment group (94.12%, 32/34) than in the control group (64.71%, 22/34) (P = 0.009).

Conclusion: Gestrinone combined with ultrasound-guided aspiration and ethanol injection therapy is an effective treatment for ovarian chocolate cyst with low recurrence rate.
