METHODS: Between May and November 2012, three male patients who developed post-operative cervical esophageal leakage were treated with E-VAC therapy. One patient had undergone surgical excision of a pharyngo-cervical liposarcoma with partial esophageal resection, and the other two patients had received surgical treatment for symptomatic Zenker's diverticulum. Following endoscopic verification of the leakage, a trimmed polyurethane sponge was fixed to the distal end of a nasogastric silicone tube and endoscopically positioned into the wound cavity, and with decreasing cavity size the sponge was positioned intraluminally to cover the leak. Continuous suction was applied, and the vacuum drainage system was changed twice a week.RESULTS: The initial E-VAC placement was technically successful for all three patients, and complete closure of the esophageal leak was achieved without any procedure-related complications. In all three patients, the insufficiencies were located either above or slightly below the upper esophageal sphincter. The median duration of the E-VAC drainage was 29 d (range: 19-49 d), with a median of seven sponge exchanges (range: 5-12 sponge exchanges). In addition, the E-VAC therapy reduced inflammatory markers to within normal range for all three patients. Two of the patients were immediately fitted with a percutaneous enteral gastric feeding tube with jejunal extension, and the third patient received parenteral feeding. All three patients showed normal swallow function and no evidence of stricture after completion of the E-VAC therapy. CONCLUSION: E-VAC therapy for cervical esophageal leakage was well tolerated by patients. This safe and effective procedure may significantly reduce morbidity and mortality following cervical esophageal leakage.展开更多
文摘目的：探讨简易封闭式负压引流技术在糖尿病足溃疡治疗中的辅助疗效。方法利用中心负压、吸痰管、湿性敷料、Opsite 透明膜等制成简易封闭式负压引流装置，对68例糖尿病足溃疡患者进行持续封闭负压引流治疗。统计68例的溃疡创面自接受简易封闭式负压引流治疗开始，至可以施行手术缝合、加压疗法或皮瓣转移的创面床准备时间，并观察有无出现治疗相关并发症及不良反应。结果68例糖尿病足溃疡经封闭负压引流治疗7-14 d （中位时间9 d）后创面床准备良好，有肉芽生长，呈颗粒状，湿润且具有光泽，渗液量较前明显减少。在此创面基础上34例行加压疗法，23例行二期手术缝合，11例行皮瓣转移，溃疡创面均完全愈合，愈合率达100％。未发现简易封闭式负压引流治疗相关的并发症和不良反应。结论简易封闭式负压引流技术能有效辅助治疗糖尿病足溃疡，且取材方便，操作简单易掌握。
