Laparoscopic resection of benign ovarian tumours in children with gonadal preservation.

PURPOSE

Ovarian tumours are often regarded as an indication for open oophorectomy, especially following torsion. We wish to report our results of laparoscopic ovarian cystectomy with ovarian preservation.

METHODS

Retrospective review of clinical records of patients who where managed with laparoscopic ovarian cystectomy with ovarian preservation.

RESULTS

Twelve records were identified over a 3-year period. The average age was 11.8 years (9-15). Presentation was of a mass in nine patients and torsion in three patients. Average size of the mass was 8.2 cm (5-18). Two patients had bilateral lesions. All patients were noted to have normal tumour markers. Successful cystectomy with ovarian preservation was accomplished in all cases using 3-port laparoscopy. The bilateral lesions were addressed at the same surgery with no increased length of stay or morbidity. In the three patients with acute torsion, an initial laparoscopic detorsion was performed with delayed laparoscopic cystectomy and ovarian preservation 7-10 days later. There was one complication of a minor umbilical port site infection. Histology was of a mature teratoma in ten cases and simple cyst in two. Six patients underwent routine ultrasonographic follow-up at 2-5 months at which time the involved ovary assumed a size and shape and blood flow comparable to the contra-lateral ovary in five patients. In one patient the affected side was smaller, 8.6 ml compared to 10 ml on the contra-lateral ovary. The remaining patients have been followed up clinically and remain asymptomatic.

CONCLUSION

Laparoscopic cystectomy with ovarian preservation can be successfully applied to benign ovarian tumours. Acute ovarian torsion is not a contraindication to this technique where a two stage procedure still enables us to offer ovarian preservation.
