Abstract

Objectives: To describe the clinical, paraclinical and rate of lymph node metastasis in patients undergoing esophagectomy with three field lymphadenectomy for esophageal carcinoma at Hanoi Medical University Hospital. Methods: A prospective descriptive study on 20 patients with esophageal carcinoma who underwent thoracoscopic-laparoscopic esophagectomy with semiprone positions. Results and discussion: Mean age 59.75 ± 6.96. All of the patients are male. The rate of neoadjuvant chemoradiotherapy was 75%. The middle third of the tumor accounted for 56.2%, the lower third accounted for 48.2%. Stages IIB and IIIB accounted for the most 31.5%, stages IA, IB, IIA all accounted for 12.5%. The average number of right neck lymphadenectomy is 13.8 ± 7.16, with 0% metastasis rate, the average number of left neck lymphadenectomy is 13.65 ± 4.8, with 5% metastasis rate. The number of lymph nodes along the right recurrent laryngeal nerve removed was 6.9 ± 3.7, with a metastasis rate of 2 cases accounting for 10%, the average number of lymph nodes along the left recurrent laryngeal nerve removed was 5.65 ± 4.85, with 5% metastasis rate. The average number of mediastinal lymphadenectomy was 18.85 ± 6.64, with a metastasis rate of 3 cases, accounting for 15%. The average number of abdominal lymph nodes removed was 11.95 ± 6.88 with 15% metastasis rate. Conclusions: The rate of cervical lymph node metastasis in our study is 5%, the rate of thoracic lymph node metastasis is 15% and the rate of abdominal lymph node metastasis is 15%
