Abstract

Background: Cervical lymph node dissection is an important component of esophagectomy with three-field lymphadenectomy (cervical, thoracic, abdominal) for esophageal squamous cell carcinoma (ESCC). However, the true benefit of this procedure regarding patient survival remains controversial. Subjects and methods: A prospective, descriptive study was conducted from November 2015 to December 31, 2022. A total of 114 patients underwent thoracoscopic esophagectomy with three-field lymphadenectomy at the Department of Digestive Surgery, Cho Ray Hospital, Vietnam. Results: The rate of cervical lymph node metastasis in ESCC patients was 14%. Tumors located in the upper third of the esophagus had a cervical metastasis rate of 50%, whereas tumors in the middle and lower thirds showed rates of 19.2% and 6.9%, respectively. The rate of cervical node metastasis according to tumor invasion depth was 13% in pT1, 23.5% in pT3, and 16.7% in pT4 tumors. Complications included cervical fluid accumulation (6.1%), chylous fistula and internal jugular venous thrombosis (2.6%), and postoperative shoulder and arm numbness (1.8%). Conclusion: The high cervical lymph node metastasis rate (14%) supports the necessity of thoracoscopic esophagectomy with three-field lymphadenectomy for esophageal squamous cell carcinoma. However, further studies are needed to thoroughly evaluate the balance of benefits and risks associated with this surgical technique.
