EVALUATION OF RECURRENT LARYNGEAL NERVE PALSY IN THORACOLAPAROSCOPIC ESOPHAGECTOMY AND EXTENDED TWO-FIELD LYMPH NODE DISSECTION FOR THE TREATMENT OF ESOPHAGEAL CANCER AT K HOSPITAL
Main Article Content
Abstract
Background: Lymph node around the recurrent laryngeal nerve (RLN) is one of the most challenging group in the lymph node dissection for esophageal cancer. This study aims to evaluate the incidence and factors related to recurrent laryngeal nerve palsy (RLNP) acquired during 3D thoracolaparoscopic esophagectomy and lymph node dissection for esophageal squamous cell carcinoma. Subjects and methods: Prospective descriptive study at K Hospital from October 2022 to March 2024 on patients with esophageal squamous cell carcinoma undergoing 3D thoracolaparoscopic esophagectomy and extended two-field lymph node dissection. Results: The incidence of grade II RLNP is 8.3%. After an average follow-up period of over 6 months, 76.9% of cases recovered completely. All of RLNP is on the left side. Age, BMI, mean intensive care unit stay and hospital stay did not differ between the two groups. It was noted that the group of patients who had preoperative chemoradiotherapy had a statistically significant higher rate of RLNP (p = 0.015; RR = 4.7; 95% CI = 1.3 - 17.0). Conclusion: The incidence of grade II RLNP is 8.3%. RLNP is related to preoperative chemoradiotherapy. It is necessary to apply technical improvements with a unified procedure in lymph node dissection around the RLN.
