Ovarian cyst impacted in the pouch of Douglas at 20 weeks' gestation managed by laparoscopic ovarian cystectomy: a case report.

INTRODUCTION

The frequency of ovarian cysts in pregnancy is reported to be 1 in 1000 pregnancies. Laparoscopic ovarian cystectomy has been described in the literature as case series but this is the first case where an ovarian cyst at 20 weeks' gestation impacted in the pouch of Douglas was managed exclusively by laparoscopy.

CASE PRESENTATION

A 31-year-old primigravida woman was diagnosed as having an 11 cm ovarian cyst at 20 weeks' gestation. At the 19th week routine ultrasound scan, the mass appeared to be cystic with no solid component. She was asymptomatic. In view of the size of the cyst, options were discussed with her including laparoscopic ovarian cystectomy which she agreed to. Laparoscopic surgery during pregnancy is reported to be safe and beneficial for pregnant women. At laparoscopy, a transvaginal scan was performed to localize the cyst and an ovarian cystectomy was carried out. The patient had an uneventful recovery and subsequent antenatal period. She had a lower segment caesarean section for non-progress of labour when both ovaries were found to be normal and mobile.

CONCLUSIONS

Laparoscopic surgery during pregnancy has numerous advantages compared to open laparotomy. This is a rare example of an ovarian cyst in the pouch of Douglas impacted behind the uterus which was managed by laparoscopy and shows the safety of the technique in the presence of an expert laparoscopic surgeon.
