{Abstract}: In the present study, the outcomes of elective neck dissection in patients with intrathoracic esophageal squamous cell carcinoma were investigated. From January 2016 to December 2022, 21 patients who underwent esophagectomy and elective neck dissection (both neck level IV) for intrathoracic esophageal squamous cell carcinoma were enrolled. Of these 21 patients, 19 patients were male and 2 were female. A total of 11 patients received concurrent chemoradiotherapy (CCRT) as preoperative treatment. As a result of elective neck dissection at both neck level IV, occult neck metastasis of esophageal squamous cell carcinoma was diagnosed in 3 cases, all of which involved left neck lymph nodes. The incidence of occult neck metastasis was statistically significant in patients with preoperative CCRT, high T stage and high N stage (P<0.05). In addition, 16 out of 21 patients had been under follow-up without disease recurrence after the completion of treatment. However, 3 out of 21 patients succumbed to esophageal squamous cell carcinoma and 2 out of 21 patients were alive with stable disease of esophageal carcinoma. The follow-up period was 19.2±18.4 months. In conclusion, three-field lymph node dissection for intrathoracic esophageal squamous cell carcinoma may be necessary in patients with certain phenotypes, such that collaboration between thoracic surgeons and otolaryngologists may help reduce surgical complications.
