Background Surgery for esophageal malignancy is associated with significant morbidity and mortality, especially in cases requiring extensive lymphadenectomy. Recurrent laryngeal nerve (RLN) injury can result in hoarseness, aspiration, pneumonia, tracheostomy, and could even be life-threatening. A 33 year old lady with a lower thoracic esophageal squamous carcinoma with left trachea-esophageal groove nodes in the superior mediastinum underwent a Xi robotic esophagectomy and three field lymphadenectomy with intra-operative recurrent laryngeal nerve monitoring after neoadjuvant chemotherapy. Methods We used a bronchial blocker (COOPDECH bronchial blocker, Daiken-Iki Corporation, Japan) with a single-lumen electromyographic (EMG) endotracheal tube) (NIM EMG endotracheal tube, Medtronic Xomed, Jacksonville, FL, USA) for lung isolation along with capnothorax. Semiprone position with 3 robotic ports and an assistant port was utilised. Nerve monitoring provided an audiovisual waveform when either the vagus or the RLN was stimulated and transformed the laryngeal muscle activity into EMG signals. Grounding electrodes were placed on the patient’s shoulder or near the sternum. A prerequisite for adequate and effective nerve monitoring is the avoidance of neuromuscular blockers during anesthesia. Results Esophageal mobilisation was done in the standard fashion. The lymphadenectomy along the recurrent laryngeal nerves in the mediastinum and neck was guided by the nerve identification and stimulation utilising the long intra-thoracic nerve monitoring probes. In the mediastinum, the right recurrent laryngeal nerve was identified taking off from the right vagus along the lateral border of the trachea and looping around the right subclavian artery. The thoracic left recurrent nerve was identified in the aorto-pulmonary window as well along the left lateral border of the trachea in the trachea-esophageal groove where the metastatic lymph nodes were identified on radiology. Conclusion Minimally invasive esophagectomy is now the preferred modality for surgical extirpation of esophageal malignancies, with extensive lymphadenectomy used in appropriate cases. Interventions to reduce postoperative morbidity resulting from the dissection of nodes around the RLN need to be used. The use of IONM is associated with lower RLN palsy rates and superior lymph nodal yield and needs to be investigated with large-scale randomized studies for beneficial clinical outcomes.
