We retrospectively reviewed the medical records of all patients treated at our institute from 1994 to 2018. A total of 3217 esophageal cancer patients were identified who underwent esophagectomy. Among these, 344 patients (10.6%) had unilateral RLNP after esophagectomy. Fifty‐six patients (1.7%) had bilateral RLNP and therefore were included in this study (Figure 1). Ethical approval was received from the institutional review board.
