Abstract

Objectives : Living donor liver transplantation (LDLT) is a life-saving therapy for patients with terminal liver disease. Many studies have focused on recipients rather than donors. The aim of this study was to assess the emotional status and personality characteristics of LDLT donors. Methods : We evaluated 218 subjects (126 male, 92 female) who visited Daegu Catholic University Medical Center from August 2012 to July 2018. A retrospective review of their preoperative psychological evaluation was done. We investigated epidemiological data and the Minnesota Multiphasic Personality Inventory-2 questionnaire. Subanalysis was done depending on whether subjects actually underwent surgery, relationship with the recipient, and their gender. Results : Mean age of subjects was $32.19{\pm}10.91years$. 187 subjects received LDLT surgery (actual donors) while 31 subjects didn't (potential donors). Donor-recipient relationship included husband-wife, parent-children, brother-sister etc. Subjects had statistical significance on validity scale L, F, K and all clinical scales compared to the control group. Potential donors had significant difference in F(b), F(p), K, S, Pa, AGGR, PSYC, DISC and NEGE scales compared to actual donors. F, D and NEGE scales were found to be predictive for actual donation. Subanalysis on donor-recipient relationship and gender also showed significant difference in certain scales. Conclusions : Under-reporting of psychological problems should be considered when evaluating living-liver donors. Information about the donor's overall psychosocial background, mental status and donation process should also be acquired.

연구목적 생체 간이식은 간 질환으로 치료가 어려운 환자들에게 타인의 간을 제공하는 치료 방법 중 하나로, 수혜자에 비해 생체 간 공여자들의 특성에 대한 연구가 상대적으로 부족하다. 본 연구는 생체 간 공여 예정자들의 정서상태와 성격 특성을 평가하고, 공여 여부와 수혜자와의 관계 및 성별에 따른 차이점 유무를 확인하고자 하였다. 방 법 2012년 8월 1일부터 2018년 7월 31일까지 대구가톨릭대학교병원 정신건강의학과 외래에 방문한 생체 간 공여 예정자 218명(남자 126명, 여자 92명)의 의무 기록을 후향적으로 검토하여 사회인구학적 특성 및 정신건강의학과적 평가에 관한 정보를 수집하였다. 공여 예정자들의 수술 시행 여부, 공여자-기증자의 관계와 성별에 따라 군을 나눈 후 사회인구학적 특성과 다면적 인성검사 II (Minnesota Multiphasic Personality Inventory-2) 척도값을 비교하였다. 결 과 대상자들의 평균 연령은 $32.19{\pm}10.91$ 세였다. 본원에서 공여자 간절제술을 받은 자는 187명, 받지 않은 자는 31명이였다. 공여자-수혜자 관계에서 남편-아내는 40명, 부모-자식은 157명, 형제-자매는 12명, 기타 친족 및 지인은 9명이였다. 대상자들은 대조군과 비교했을 때 타당도 척도 L, F, K와 모든 임상 척도에서 유의미한 차이를 보였다. 공여자 간절제술을 받은 대상자들은 받지 않은 대상자들에 비해 타당도 척도 K와 S에서 유의미하게 높은 수치를, 타당도 척도 F(b)와 F(p) 및 임상 척도 Pa와 함께 성격병리 척도 AGGR, PSYC, DISC, NEGE에서 유의미하게 낮은 수치를 보였다. 공여자 간절제술 시행 여부의 예측 변인으로 타당도 척도 F, 임상 척도 D와 성격병리 척도 NEGE가 있었다. 공여자-수혜자 관계와 성별에 따른 차이점을 비교하였을 때, 일부 척도들에서 통계적으로 유의미한 차이를 보였다. 결 론 생체 간 공여자들의 평가에서 심리적 문제의 축소 보고 가능성을 유념해야 한다. 또한 공여자들을 평가할 때 정서 상태, 공여를 결정하기까지의 과정과 배경, 가족 구성원들과의 관계 또한 파악하는 것이 필요하겠다.
