Abstract:

Objective To analyze the clinical manifestation and treatment effect of endometriosis（EMs） in adolescent，to explore appropriate treatment and timingfor adolescent EMs patients. Methods We retrospectively analyzed the clinical data of 89 adolescent（age ≤ 21 years）EMs patients hospitalized from 2011 to 2018. Eighty⁃ six patients were diagnosed as ovarian endometrioma（OE）and 3 patients as peritoneal EMs.Withrandom sampling， another 89 adult OE patients hospitalized in the same periodwere enrolled for comparative analysis. Results （1） Compared to those in adult group，higher dysmenorrhea rate；shorter interval time from dysmenorrhea happened to menarche and earlier menarche age were found in adolescent group.（2）Adolescent group had larger cyst diameter than adult group（P < 0.005）and 9 patients had underwent emergency surgery because of ovarian cyst rupture. （3）Laparoscopic conservative surgery was completed successful in 91.01% of the patients in adolescent group and in 86.52% in adult group. Most of the patients were diagnosed as stage Ⅲ/Ⅳ in the two groups.（4）Dysmenorrhea release rate and 3 years post operation recurrence rate was 68.29%（28/41）and 18.87%（10/53）respectively in adolescent group. Close of Douglas′ cul ⁃ de ⁃ sacmay have relationship with post operation recurrence. Conclusion Adolescent EMs is featured by early onset，and OE is the mainly classification. OE of adolescent patients has the featuresof larger ovarian cyst diameter than OE of adult patients and has the possibility to rupture，which requires surgery as soon as possible. Laparoscopic conservative surgery is an effective treatment for OEin adolescent patients， and close of Douglas′ cul⁃de⁃sacmay have relationship with post operation recurrence.
