ABSTRACT

An esophagorespiratory fistula (ERF) is an often fatal consequence of esophageal or bronchogenic carcinomas. The preferred treatment is placement of esophageal and/or airway stents. Stent placement must be performed as quickly as possible since patients with ERFs are at a high risk for aspiration pneumonia. In this review, choice of stents and stenting area, fistula reopening and its management, and the long-term outcome in the interventional management of malignant ERFs are considered. Lastly, a review of esophagopulmonary fistulas will also be provided.

ABSTRACT

BACKGROUND: Implantation of esophageal stents is nowadays considered as the method of choice for the management of esophagorespiratory fistula. However, implantation of conventional plastic prosthesis is inconvenient for the patient and associated with relativelty high mortality and complications. Silicone coated self expandable metal stents have been developed to overcome these limitations of plastic tubes. And then, the efficacy of silicone-coated self expandable metal stents in esophagorespiratory fistulas was investigated. METHODS: Six patients with esophagorespiratory fistulas were treated with silicone-coated self expandable metal stents(Song's esophageal stents). All six patients were unable to swallow food or water before treatment due to aspiration via esophagorespiratory fistula. The stents were inserted under endoscopic and fluoroscopic guidence. Clinical improvement was determined by grading food intake capacity on five-point scale : none, liquid, soft food, solid food, or all food. RESULTS: The stents were successfully inserted in all patients. All stents spontaneously showed sufficient expansion without further endoscopic control. After procedure, all fistulas were sealed and symptoms due to branchial aspiration were disappeared. Dysphagia improved by at least two grades in 5 of the 6 patients(83.3%). One patient died due to massive hemoptysis 11 days after stent placement, which could be regarded as a complication. Retrosternal and epigastric pain were observed in three patients. In the follow-up, tumor overgrowth at the end of the stent was found in one patient, who was retreated with implantation of another stent. CONCLUSION: These results suggest that implantation of silicone-coated self expandable metal stents is a rapid, and effective procedure for the palliative treatment of malignant esophagorespiratory fistulas and other cause of esophagorespiratory fistula.

ABSTRACT

BACKGROUND: Esophageal cancer can induce progressive dysphagia and occasionally develop esophagorespiratory fistulas. Surgically incurable disease is present in over 60% of patients at the time of presentation and in such a means, relief of dysphagia is one of the important treatment modes in the majority of these patients. Implantation of stents is widely used for improvement of dysphagia and sealing of esophagorespiratary fistulas. METHODS: Silicone-covered self-expandable metal stents were used in 19 consecutive patients with malignant esophageal obstruction (n=14) or esophageal obstruction with esophagorespiratory fistulas (n=5). RESULTS: The stents were successfully inserted in all patients. Dysphagia improved in 18 of 19 patients (95%). All fistulas were sealed and symptoms due to bronchial aspiration disappeared. Complications occurred during follow-up including chest pain (11 patients), aspiration pneumonia (4 patients), reflux esophagitis (2 patients), stent migration (2 patients), tumor overgrowth (2 patients) and hemorrhage (1 patient). Three of the 4 patients with aspirtion pneumonias and a patient with hemorrhage suffered from dysfunction of upper esophageal sphincter after implantation of stents in upper esophageal carcinoma. But, Tumor ingrowth and perforation did not occur. Two patients died of massive hemorrhage and respiratory failure caused by aspiration pneumonia. CONCLUSION: These results suggest that implantation of silicone-covered self-expandable metal stents is a rapid and effective procedure for the palliative treatment of malignant esophageal obstruction and esophagorespiratory fistulas.
