Abstract

Background: Pulmonary complications in immunocompromised patients are often fatal. Empirical treatment is usually applied based on the clinical and radiological findings because of the risk of the aggressive diagnostic procedures such as open lung biopsy. However, recent advancements in operative procedures and perioperative management has decreased the procedure-related risks. We have prospectively analyzed the risks and benefits of the early application of open lung biopsy in such patients. Material and Method: Forty-two consecutive immunocompromised patients with critical pulmonary complications were included from June, 1996 to December, 1999. The definition of the immunocompromised is as those with chemotherapy and/or other modality for hematologic disorders, with usage of immunosuppressive drug after transplantation, with usage of steroid for more than 1 month, and with primary immunodeficiency disorders. The indication of open lung biopsy was those with no significant improvement after a week of aggressive application of empirical treatment or with rapidly aggressive process. The underlying disease included hematologic disorder(31 patients), post-transplantation(3 patients), chemotherapy for solid tumor(2 patients), and others(6 patients). Operations were done through thoracotomy(conventional or mini-) or VATS.

배경: 면역저하 환자에게 발생하는 폐 합병증은 흔히 치명적이다. 폐생검술과 같은 침습적인 진단 술기의 위험도 때문에 일반적으로 임상 양상과 방사선 영상 소견에 근거하여 경험적인 치료가 적용된다. 그러나 최근 수술 술기와 수술 전후의 환자 관리의 발전으로 인해 술기와 연관된 위험도는 줄어든 실정이다. 이에 폐합병증을 동반한 심한 면역저하 환자에서 시행된 폐생검술의 위험성 및 유효성에 대하여 전향적으로 분석하였다. 대상 및 방법: 1996년 6월부터 1999년 12월까지 폐합병증을 동반한 면역저하 환자 42명에서 43례의 폐생검술을 실시하였다. 면역저하는 다음과 같이 정의하였고(1, 혈액학적인 질환으로 인해 화학요법이나 다른 치료를 동반하여 받은 경우, 2. 이식 수술 후 면역 억제제를 복용하는 경우, 3. 1 개월 이상의 스테로이드 복용, 4. 원발성 면역결핍 질환), 이상의 면역저하 환자에서 새로운 폐합병증을 동반하고 1 주간의 경험적 치료에 호전이 없거나 급속하게 진행되는 경우를 대상으로 하였다 기저 질환은 혈액학적 질환(31명), 이식 수술 환자(3명), 고형암으로 인한 화학요법(2명)등이었으며 수술은 개흉술이나 video-aided thoracoscopic surgery (VATS)를 통하여 이루어 졌다.
