Abstract
STUDY OBJECTIVE: To assess the rate of recurrence of ovarian dermoid cysts in pediatric and adolescent girls at the Hospital for Sick Children. DESIGN: A retrospective chart review of all dermoid cysts surgically managed at the hospital for Sick Children from January 2003 to June 2012. SETTING: The Hospital for Sick Children, Toronto, Canada. PARTICIPANTS: 66 adolescent and pediatric patients <18 years old treated with ovarian cystectomy of their dermoid cysts by either laparoscopy (n = 40) or laparotomy (n = 26). MAIN OUTCOME MEASURES: Total dermoid cyst recurrence, recurrence after laparoscopy versus laparotomy, follow-up imaging completed and ultrasonographic identification of other ovarian cysts in follow-up. Data was assessed with Fisher exact test where appropriate (P < .05). RESULTS: The mean age of patients at time of surgery was 12.9 years (range 2.5-18.1). 25/66 (38%) of patients received no follow-up, 6/66 (9%) were followed by a single ultrasonography and 35/66 (53%) were followed with annual ultrasonography for up to 5 years. 35 patients completed their initial ultrasonography where 19/35 (54%) patients had new ovarian cysts diagnosed including: 6 functional/hemorrhagic, 3 dermoid, and 10 unspecified cysts. All new dermoids were suspected at first follow-up ultrasonography (6/35), but 3 required a second follow-up ultrasonography for confirmation. Overall, 7/66 (11%) patients had recurrent or persistent dermoid cysts of which 2 (3%) required repeat surgery. There was no significant impact on the type of surgery and dermoid recurrence. CONCLUSION: The incidence of recurrent dermoid cysts in a pediatric and adolescent population following ovarian cystectomy is 10.6% where only 3% will recur and require further surgical management.
