Abstract

Objectives: The aim of this study was to assess the change of ovarian reserve after removal of ovarian tumor using basal FSH, $E_2$, clomiphene citrate challenge test and ovarian volume. Methods: Twenty two patients with unilateral ovarian tumor, ${\leq}35$ years old, regular menstrual cycle were collected prospectively and divided into endometrioma or non-endometrioma group. We measured the ovarian volume with transvaginal ultrasonography on the day 3 of menstrual cycle within one month before and 3 months after surgery. Basal (cycle day 3) FSH, $E_2$ and CCCT were checked before surgery and repeated at least 2 spontaneous cycles later after surgery. Three patients that had been pregnant within 3 months after surgery were excluded in analysis. Results: The ovarian volume was reduced significantly after surgery in endometrioma and non-endometrioma ${\geq}10\;cm$ group ($4.79{\pm}2.57\;cm^3$ and $5.21{\pm}1.33\;cm^3$, respectively), but not in the non-endometrioma <10 cm group ($6.18{\pm}2.85\;cm^3$). After surgery, basal FSH and cycle day 10 FSH on CCCT in endometrioma and non-endometrioma were $4.25{\pm}0.20\;mIU/ml$ and $3.79{\pm}0.80\;mIU/ml$, $4.24{\pm}0.85\;mIU/ml$ and $4.28{\pm}0.92\;mIU/ml$, respectively. There were neither significant difference in comparison with the preoperative results nor between two groups. Conclusions: Enucleation of ovarian mass was associated with a significant reduction in ovarian volume in endometrioma and non-endometrioma larger than 10cm in diameter. Hormonal markers for evaluation of ovarian reserve, such as basal and cycle day 10 FSH on CCCT, were not changed significantly in each group. In reproductive age women, conservative enucleation or cystectomy rather than oophorectomy should be considered even in a large benign tumor and ovarian function could be reserved by meticulous operative technique.

목 적: 난소 용적 측정 및 기저 FSH, $E_2$, CCCT 검사를 통하여 가임기 여성에서 난소 낭종 제거술후 난소 배란능의 변화를 평가하고자 하였다. 연구방법: 난소 낭종으로 내원한 환자 중 35세 이하의 여성으로서 비교적 규칙적인 생리주기를 가지며 한쪽 난소에만 낭종을 가진 22명을 대상으로 자궁내막종군과 비자궁내막종군으로 구분하여 전향적 비교 분석을 시행하였다. 질 초음파를 이용하여 수술 1개월 전과 수술 3개월 후 생리주기 3일에 난소의 용적을 측정하였다. 또한 수술 전과, 수술 후 두 번의 정상 생리가 있은 뒤 기저 FSH, $E_2$, CCCT를 시행하였다. 대상 환자 22명 중 3명은 술후 검사를 계획한 3개월 전에 임신이 됨으로써 연구대상에서 제외하였다. 결 과: 수술 후 난소 용적은 자궁내막종군에서 $4.79{\pm}2.57\;cm^3$, 비자궁내막종군 중 직경 ${\geq}10\;cm$인 경우에서 $5.21{\pm}1.33\;cm^3$로서 건측과 비교하여 유의한 감소가 있었으나, 비자궁내막종군 중 직경 <10 cm인 경우는 $6.18{\pm}2.85\;cm^3$로서 유의한 용적 감소가 없었다. 수술후 자궁내막종군의 기저 FSH는 $4.25{\pm}0.20\;mIU/ml$, CCCT 10일째 FSH는 $3.79{\pm}0.80\;mIU/ml$였고, 비자궁내막종군은 각각 $4.24{\pm}0.85\;mIU/ml$, $4.28{\pm}0.92\;mIU/ml$로서 수술 전후의 기저 FSH, CCCT 결과 비교에서 각 군 모두 유의한 차이가 없었으며, 두 군간의 비교에서도 유의한 차이가 없었다. 결 론: 자궁내막종 절제술 및 10 cm 이상의 난소 낭종 절제술 후 난소 용적은 유의한 감소를 보였으나 10 cm 미만의 난소 낭종 제거술에서는 난소 용적의 유의한 감소가 없었다. 난소 배란능을 평가하기 위하여 측정한 기저 FSH, CCCT 검사 결과는 낭종 제거술 후에도 각 군 모두 유의한 차이를 보이지 않았다. 따라서 가임기 여성에서는 난소절제술 보다는 낭종 제거술이 우선 고려되어야 하며, 세심한 주의를 기울인다면 난소 배란능의 손상을 최소화할 수 있을 것으로 사료된다.
