Abstract

Abstract: Objective To study the effect of minimally invasive esophagectomy (MIE) on right recurrent laryngeal nerve lymph nodes,and the characteristics of lymph node metastasis.Methods The clinical data of 80 cases of thoracic esophageal cancer and receiving MIE from January 2012 to June 2015 were analyzed retrospectively.Right recurrent laryngeal nerve lymph node metastasis and clinical pathological features were analyzed.Results (1) In all the patients receiving MIE,the total and average number of right recurrent laryngeal nerve lymph nodes were 322 and 4.0 per case (322/80),respectively,similar to the results by thoracotomy.Twenty-six cases were confirmed by pathology with right recurrent laryngeal nerve lymph node metastasis,and the metastasis rate was 32.5% (26/80).(2) Right recurrent laryngeal nerve lymph node metastasis was found in 21 (42.0%) patients with upper and middle segment esophageal cancer and 5(16.7%) with lower segment esophageal cancer,and the metastasis rate was higher in the patients with upper and middle segment esophageal cancer than in those with lower segment esophageal cancer (χ²=4.39,P<0.05).The metastasis rates in the well differentiated and moderately-poorly differentiated groups were 9.1% and 48.9%,respectively,and the difference was significant (χ²=12.27,P<0.01).The right recurrent laryngeal nerve lymph node metastasis rate was higher in the patients with vascular invasion (57.1%) than those without (25.8%) (χ²=3.94,P<0.05).Lymph node skip metastasis was found in 26 cases with lymph node metastasis.Conclusion In the patients with thoracic esophageal,right recurrent laryngeal nerve lymph nodes metastasis is common and the metastasis rate is closely related with tumor differentiation degree,tumor site,and vascular invasion.It is necessary to perform right recurrent laryngeal nerve lymph node dissection during thoracic esophagectomy.
