Short-term and long-term effects of recurrent laryngeal nerve injury after robotic esophagectomy.

Abstract

BACKGROUND:

Robot-assisted minimally invasive esophagectomy (RAMIE) was reported to have superiority in upper mediastinal lymph nodes dissection than traditional approach, but related injuries to recurrent laryngeal nerve (RLNI) cannot be avoided. Considering that there is no study centering on RLNI during robotic manipulation, this study aimed to investigate the impact of RLNI on the short-term and long-term outcomes after RAMIE.

METHODS:

Patients with esophageal cancer (EC) who underwent RAMIE from June 2015 to July 2019 were collated from a prospectively maintained database. Short-term and long-term outcomes of RLNI were analyzed.

RESULTS:

A total of 409 patients were included with the incidence of RLNI being 18.6% (76/409). A higher rate of postoperative pulmonary complications including pneumonia (P < 0.001) and acute respiratory distress syndrome (ARDS) (P = 0.041) was associated with RLNI, requiring more interventions for bronchoscopy airway suction (P < 0.001), tracheal reintubation (P = 0.013) and tracheostomy (P < 0.001). Patients with RLNI had a prolonged length of hospitalization and intensive care unit (ICU) stay (P < 0.001). With the median follow-up time of 48.7 (interquartile range [IQR]:27.6-60.9) months, recurrence in regional lymph nodes at mediastinum did not differ between groups (P = 0.351). Similarly, the Kaplan-Meier curves revealed no significant divergency for overall survival after RLNI (P = 0.452).

CONCLUSIONS:

RLNI after robotic esophagectomy is a serious morbidity associated with an increased rate of pulmonary complications, prolonged length of hospitalization with limited influence on long-term prognosis.
