食管-纵隔瘘:食管覆膜内支架与经鼻经食管引流管置入治疗

目的探索食管覆膜内支架与经鼻经食管引流管置入治疗食管-纵隔瘘的价值。方法10例食管-纵隔瘘采用5F直头侧孔导管经鼻腔经食管和瘘口置入纵隔脓腔，并利用食管覆膜内支架封堵瘘口。经引流管定时冲洗脓腔，复查脓腔造影，及时调整引流管的位置和拔出引流管。结果进食顺利，引流10—25d引流管完全拔出，脓腔消失。结论食管覆膜内支架与经鼻经食管引流管置人治疗食管-纵隔瘘，可有效治疗纵隔脓肿，操作技术简单、费用低、创伤小，患者易于接受，是值得推广的新技术。

Treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube

Objective To investigate the value of treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube. Methods Ten patients with mediastinoesophageal fistula were treated by 5F catheter inserting into the abscess cavities through nasal esophageal fistula, with stent placement in the esophagus. The abscess cavities were washed and angiograghied through drainage tube and the sites of the drainage tube were adjusted in time untill withdrawal of the tube. Results The drainage tubes were pulled out within 10-25 days with disappearance of the abscess cavities and normal diet intake without difficulty. Conclusions Treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube is safe, microinvasive economic and acceptable, worthy to be recommended.
