Abstract

Background: Descending necrotizing mediastinitis (DNM) is a serious disease originating in odontogenic or oropharyngeal infection with high mortality despite adequate antibiotics and aggressive surgery. We analyzed results of treatment for DNM. Material and Method: We studied 8 cases diagnosed as DNM from 1998 to 2007. All patients received emergent surgical drainage and debridement with broad spectrum antibiotics just after diagnosis. Antibiotics were changed after bacterial susceptibility testing. The surgical approach included 2 cases of cervicotomy, 6 cases of cervicotomy, and a thoracotomy. Result: The interval between symptom onset and hospitalization was $4.6{\pm}1.8$ days ($1{\sim}9$ day). DNM originated in 4 cases of odontogenic infection (50%), 2 cases of oropharyngeal infection (25%), and 2 cases of unknown origin (25%). Causative organisms were found in 6 cases; Streptococcus in 4 cases, Staphylococcus in 1 case, and Klebsiella in 1 case. The Endo DNM classification was type I (2 cases), IIA (3 cases), and IIB (3 cases). The incidence of thoracotomy was 75%. The surgical mortality rate was 25% (2/8). The cause of death was multiple organ failure caused by septic shock. All mortality cases received only cervicotomy and aggravated infections after initial drainage. Conclusion: Early diagnosis, immediate surgical drainage, and adequate antibiotics, including covered anaerobes, are required. Thoracotomy should be performed with cervicotomy even for localized DNM.

배경: 하행성 괴사성 종격동염은 구인두에서 염증이 발생한 후 경부간막을 통해 종격동으로 진행함으로써 발생하는 종격동 결체조직의 중증 염증질환이며, 적절한 항생제의 사용과 적극적인 배농술에도 여전히 높은 사망률을 보인다. 본 연구에서는 하행성 괴사성 종격동염으로 진단되어 치료한 환자들의 수술 전 상태, 수술방법, 수술 후 경과등에 대한 성적을 분석하였다. 대상 및 방법: 1998년 9월부터 2007년 8월까지 8명의 환자가 하행성 괴사성 종격동염으로 진단되어 치료하였다. 모든 환자에서 진단 즉시 광범위 항생제를 사용하면서 응급 배농술을 시행하였고, 세균학적 감수성 검사에 따라 항생제를 선택, 사용하였다. 수술방법으로는 경부수술만 시행한 경우가 2예, 경부 및 개흉술을 통하여 수술한 경우가 6예였다. 결과: 증상발현부터 내원까지의 기간은 평균 $4.6{\pm}1.8$일($1{\sim}9$일)이었다. 감염의 원인으로는 치성감염이 4예(50%), 인두 농양이 2예(25%), 불명확한 경우가 2예(25%)였다. Endo 등의 분류에 따라서는 I형이 2예, IIA형이 3예, IIB형이 3예였으며, 원인균은 6예에서 동정되었는데, 연쇄상구균이 4예, 포도상구균이 1예, 클렙시엘라균이 1예였다. 개흉술의 비율은 75%였다. 수술 후 2명의 환자가 사망하여 사망률은 25%였고, 사망의 원인은 모두 패혈증성 쇼크에 의한 다발성 장기부전이었다. 사망 환자들은 모두 초기 배농을 경부절개만 시행하였던 경우였으며, 염증조절이 실패한 경우였다. 결론: 하행성 괴사성 종격동염은 조기진단이 필수이며, 진단 후 혐기성 균을 제어할 수 있는 항생제를 포함한 충분한 항생제 투여와 함께 즉각적인 배농을 시행하여야 한다. 배농시에는 비록 국한적인 염증이라고 판단되더라도 경부절개 및 적절한 흉부접근을 통해 적극적으로 시행하여야 하겠다.
