Tracheoesophageal Diversion and Laryngotracheal Separation Procedures for Radiotherapy-Related Intractable Aspiration Pneumonia in Nasopharyngeal Carcinoma

Figure 2

The complete control of aspiration pneumonia in one patient. (a) The patient was receiving jejunal tube feeding due to recurrent aspiration pneumonia in 2017. (b) Aspiration pneumonia still occurred one year after tube feeding began. (c) The lung condition had completely improved one year after surgery. (d) A postoperative angiography image taken during swallowing that shows the contrast agent entered the esophagus through the larynx and the tracheal-esophageal anastomosis (blue arrow). (e) At three months after surgery, the fiber laryngoscope passed through the larynx and the trachea. Unobstructed tracheal-esophageal anastomosis was observed, with mild edema in the surrounding areas. (f) Esophageal secretions observed through the anastomotic site.
