Controversy about the adequate extent of lymph node (LN) dissection persists in surgery for thoracic esophageal squamous cell carcinoma (ESCC). The present study estimates the feasibility and strategy of common hepatic artery LN dissection during ESCC surgery.The clinical data of 482 patients with ESCC, who underwent thoracolaparoscopic esophagectomy at Fujian Medical University Union Hospital, were retrospectively selected. Among the 482 ESCC patients, 224 patients underwent thoracolaparoscopic esophagectomy with routine common hepatic artery LN dissection (cohort 1), while 258 patients underwent the same procedure without common hepatic artery LN dissection (cohort 2). The proposed operation method was introduced to safely dissect the common hepatic artery LN. Both univariate and multivariate analyses were performed to analyze the clinicopathological factors correlated to the common hepatic artery LN metastasis.The main postoperative complications were pneumonia, anastomotic leakage, vocal cord palsy and cardiovascular disease. There was no significant difference in the incidence of major postoperative complications between the 2 cohorts (P >.05), and the incidence was similar in a number of reports. The metastatic rate of common hepatic artery LNs was 4.91%, which was relatively lower. Based on the logistic regression analysis of 5 factors, tumor location and T classification were risk factors for common hepatic artery LN metastasis (P <.05).Routine common hepatic artery LN dissection is safe and feasible during a thoracolaparoscopic esophagectomy for ESCC. Although the metastatic rate is lower, common hepatic artery LN dissection should be performed for lower thoracic ESCCs, especially for tumors that invade the outer membrane.
