Palliative management of a malignant tracheoesophageal fistula using repeat endobronchial laser debridement and esophageal stenting.

A 71-year-old female presented with progressive dysphagia and unexplained weight loss. Computed tomography and esophagogastroduodenoscopy (EGD) revealed invasive esophageal squamous cell carcinoma, which was initially treated with local radiation and esophageal stenting. Over the next year, the patient experienced multiple symptoms and hospital admissions consistent with a malignant tracheoesophageal fistula, despite negative findings on imaging, bronchoscopy, and EGD. Prophylactic antibiotics were initiated based on symptomatology to prevent septic episodes. Stent erosion into the membranous trachea was eventually observed. Neodymium-yttrium-aluminum-garnet laser bronchoscopy was used periodically to debulk the invading tumor around the stent. A percutaneous endoscopic gastrostomy tube was also inserted to facilitate enteral nutrition and avoid aspiration pneumonia. The patient reported significant improvements in respiratory symptoms following each laser debridement and has progressed well beyond the life expectancy associated with malignant tracheoesophageal fistula.
