Abstract:
Objective:To explore the clinical manifestation and treatment strategy for descending necrotizing mediastinitis (DNM).
Methods:A total of 27 cases diagnosed as DNM from January 2010 to August 2018 in the First People’s Hospital of Foshan were reviewed. There were 16 males and 11 females, age ranged from 16 to 84 years. The clinical data were collected. SPSS 16.0 software and chi square test were used for statistical analysis.
Results:ALL 27 cases were diagnosed as DNM by contrast-enhanced CT scan of the neck and chest. Among the 27 cases, 13 cases resulted from peritonsillar abscess, 8 cases from esophageal foreign body perforation, 5 cases from parapharyngeal and retropharyngeal space abscess, and one case from infection of oral cavity. These 27 cases were divided into three subtypes according to the sites of mediastinitis, including 11 cases for typeⅠ, 5 cases for type ⅡA and 11 cases for type ⅡB. Of 27 cases, 20 cases underwent transcervical drainage for DNM, of which 5 cases with tracheotomy and 6 cases with thoracic drainage, and finally 19 of the 20 patients were cured, and one patient died of bacteremia; 7 cases refused to received surgery and were routinely treated with antibiotics, of which, one case was cured and 6 cases died. The curative rate in patients underwent surgery was significantly higher than that in patients treated with medication (χ2=13.638, P<0.001). Among the 20 cured cases, 4 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis, while in the 7 died cases, 5 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis. The comorbidity rates of diabetes mellitus (χ2=4.074, P=0.044) and necrotizing fasciitis (χ2=4.457, P=0.035) in died cases were significantly higher than those in cured cases.
Conclusion:DNM is a serious infection, with high mortality especially in patients with diabetes and necrotizing fasciitis. Timely cervical and chest enhanced CT scan play vital role in its diagnosis. DNM can be treated effectively with transcervical drainage.
