Until now, neoadjuvant therapy plus surgical resection of the primary tumor and potential metastatic lymph nodes (LNs) has been the current optimal treatment for locally advanced thoracic esophageal cancer (EC). LN metastasis is one of the most negative prognostic factors for thoracic esophageal squamous cell carcinoma (ESCC). However, the extent of LN dissection for thoracic ESCC has long been controversial worldwide. LNs along the recurrent laryngeal nerve (RLN) were reported to have the highest frequency of metastases in thoracic ESCC, so lymphadenectomy along the bilateral RLN is necessary but quite challenging because of a high frequency of recurrent nerve palsy and related postoperative complications. With the development of minimally invasive devices and techniques in recent years, minimally invasive esophagectomy (MIE) has been widely applied in EC surgery. The topics of what the optimal extent of lymphadenectomy is and how the recurrent nerve should be well protected during MIE have been debated in recent years. The purpose of our review is specifically to address the patterns of LN metastasis, the extent of LN dissection, and the protection of the RLN in MIE for thoracic ESCC.
