Background: This study aims to report our experience with esophageal self-expendable metal stents for the palliation of malignant dysphagia and tracheoesophageal fistulas caused by lung cancer.

Methods: Esophageal self-expandable metal stents were deployed in 56 patients (55 males, 1 female; mean age 63.5 years; range, 42 to 79 years) with malignant dysphagia due to lung cancer between August 2002 and May 2018. Of the patients, 34 had received previous chemoradiotherapy, eight only chemotherapy, and three only radiotherapy, while four had pneumonectomy. Tracheoesophageal fistula was coexisting in 12 patients (21%). Stents were inserted under fluoroscopic control over guide-wire in 28 patients and under flexible endoscopic control in the remaining 28 patients. One stent was used in all patients, except two patients with tracheoesophageal fistula, one patient who had an external compression causing downward migration of stent, and two patients who had tumor progression.

Results: Dysphagia improved in all patients after stent insertion. Tracheoesophageal fistula was sealed off in all patients. All patients remained asymptomatic without dysphagia symptoms during the follow-up period except for two patients who underwent gastrostomy. All patients with tracheoesophageal fistula died. Their mean duration of survival was 2.8 months. Of the patients with tracheoesophageal fistula, one died of mediastinitis, one died of esophageal perforation, while the others died of cancer-related reasons. Of the dysphagia patients without tracheoesophageal fistula, all died except for two patients. Mean duration of survival in this group was 4.3 months.

Conclusion: Dysphagia in lung cancer may have many underlying reasons. Self-expandable metal stents may provide satisfactory relief of dysphagia symptoms with minimal morbidity after a single procedure in patients with limited lifespan.
