Laparoscopic management of giant ovarian cysts in adolescents

A laparoscopic approach to giant ovarian cysts in girls, when the cyst's size exceeds the umbilicus, may be difficult regarding the risk of cyst rupture and limited working space. We present a series of three 12-year-old girls with giant ovarian cysts treated by percutaneous drainage under ultrasonographic guidance followed by laparoscopic resection. Clinical, laboratory and radiological diagnosis showed no signs of malignancy. After induction of general endotracheal anaesthesia, under ultrasonographic guidance, a 10 F vesicostomy catheter was placed into the cyst. Two to 4 l of serous (in one case mucinous) fluid were drained from the cyst. During laparoscopy, the abdominal cavity was inspected by the scope and no signs of malignancy were found. The laparoscopic procedure was completed with excision of the cyst and keeping some ovarian tissue in all cases. No intraoperative complications were observed. The mean operation time was 73 min. Pathological examination revealed a mature cystic teratoma in two cases and mucinous cystadenoma in one. The postoperative recovery was uneventful in all girls and they were discharged home on postoperative day 2-4 with minimal pain. The ultrasound scans and tumour markers were normal on follow-up after 3 and 6 months. Laparoscopic excision of giant ovarian cysts after ultrasound-guided drainage seems to be a safe and applicable treatment modality in pre-menarchal girls with a normal tumour marker profile and benign features of the cyst, excluding the possibility of malignancy.
