Reconstruction of recurrent laryngeal nerve with involvement by metastatic node in esophageal cancer.

BACKGROUND

Recurrent laryngeal nerve paralysis represents one of the major complications in esophageal cancer surgery, and patients with esophageal cancer sometimes develop recurrent laryngeal nerve paralysis before treatment. We evaluated recurrent laryngeal nerve reconstruction in patients with lymph node metastasis infiltrating the recurrent laryngeal nerve.

METHODS

Five patients with preoperative recurrent laryngeal nerve paralysis as a result of involvement of metastasis were enrolled in the present study. Ansa cervicalis-recurrent laryngeal nerve anastomosis in the neck was performed in 4 patients and direct anastomosis of recurrent laryngeal nerve in the mediastinum in 1 patient.

RESULTS

Six months after surgery, 3 patients who had undergone ansa cervicalis-recurrent laryngeal nerve anastomosis in the neck displayed good quality of life without hoarseness or aspiration. The patient who underwent direct anastomosis of the recurrent laryngeal nerve in the mediastinum experienced occasional aspiration and hoarseness. The remaining patient displayed poor condition because of recurrent lung tumor, and quality of life was decreased.

CONCLUSIONS

If patients with recurrent laryngeal nerve paralysis before treatment can undergo potentially curative resection with lymph node dissection, including the metastatic lymph node infiltrating the recurrent laryngeal nerve, recurrent laryngeal nerve reconstruction should be performed to improve quality of life.
