Management of patients with bilateral recurrent laryngeal nerve paralysis following esophagectomy.

Abstract

BackgroundRecurrent laryngeal nerve paralysis (RLNP) is a common complication after esophagectomy which can cause severe pulmonary complications. However, bilateral RLNP has been rarely reported in esophagectomy patients. The objective of our study is to investigate the clinical significance of patients who had bilateral RLNP following esophagectomy.MethodsWe retrospectively reviewed patients who underwent esophagectomy at a single center from 1994 to 2018. Among these, patients with bilateral vocal cord paralysis were included in this study.ResultsA total of 3217 patients were reviewed and 400 (12.4%) patients had RLNP, including 56 patients with bilateral RLNP identified by laryngoscopic examination. During the postoperative managements, 10 of the 56 patients (17.9%) required tracheostomy. Among them, two died of acute respiratory distress syndrome and the other eight patients were discharged after removing the tracheostomy tube. The median lengths of hospital and intensive care unit stay were 19.5 (range 8–157) and 2 (range 1–46) days, respectively. Forty‐six patients (83.6%) were discharged with oral feeding after swallowing therapy including tongue holding maneuver and head tilt exercise. The other five patients (8.9%) were discharged with alternative enteral feeding via jejunostomy, but they were able to achieve oral diet 2–3 months after surgery.ConclusionBilateral RLNP following esophagectomy was rare, but it required great attention to prevent severe respiratory complications. However, only a few patients required tracheostomy and the majority achieved oral ingestion after intensive rehabilitation. Feeding education and respiratory rehabilitation are critical during the management of patients with bilateral RLNP.
