食管支架治疗恶性食管-气管瘘

目的探讨国产金属被膜内支架经食管置人，治疗食管一气管瘘的疗效。方法9例中，男7例，女2例，年龄46～72岁，平均53．4岁。因放疗引起食管一气管瘘食管癌3例，肺癌1例；肺癌支气管动脉灌注治疗后2例，手术后复发病人3例。全组病例均有饮水呛咳，吞咽困难，并均经手术或内镜病理证实，造影发现有食管一气管瘘口。病理结果为；小细胞肺癌2例：肺鳞癌1例；食管鳞癌6例。支架上端呈漏斗状，上下长于病灶2cm，支架到位后，用直径1．5cm球囊导管扩张，封闭瘘口，固定支架。结果5例可进普食，4例进半流食，1周后改进普食。结论带膜金属内支架治疗食管一气管瘘安全有效，是首选的治疗方法。

Treatment of malignant esophago-tracheal fistula with intraesophageal stent

Objective To evaluate the therapeutic effects of intraesophageal metallic stent with a membrane in malignant esophago - tracheal fistula. Methods Nine patients with radiographically shown and surgically or endoscopy proven malignant esophago - tracheal fistula in which 3 cases of esophageal cancer and 2 cases of lung cancer were induced by radiotherapy, 1 case of lung cancer was induced by bronchioarterial infusion treatment and remainder 3 cases were due to postoperative reoccurrence underwent to set stent with 2 cm longer than superior and inferior segment of the lesion into the cancerous stenosed segment of the esophagus. The lesions histopathologically showed that pulmonary small cell cancer was found in 2 cases, pulmonary squamous cell cancer in 1 and esophageal squamous cell cancer in 3. Results After the operation 5 patients could immediately eat some common foods, 4 patients could eat some half- fluid foods and then changed into common foods after one week Conclusion The metallic stent setting into the cancerous stenosed segments of esophagus is a very safe and effective for treating malignant esophago - tracheal fistula and should be taken as a first selective method.
