Abstract:
Objective:To investigate the clinical efficacy of Da Vinci robot-assisted superior mediastinum lymph node dissection around recurrent laryngeal nerve.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 404 patients with esophageal cancer who underwent Da Vinci robot-assisted esophagectomy in Tianjin Medical University Cancer Hospital and Institute from June 2017 to June 2022 were collected. There were 349 males and 55 females, aged (62±8)years. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) comparison of clinical features in patients who were admitted in different time periods. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the one way ANOVA. Measurement data with skewed distribution were represented as M(IQR), and comparison among multiple groups was conducted using the Kruskal-Wallis H test. Count data were described as absolute numbers or percentages, and com-parison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Intraoperative conditions. The operation time, volume of intraoperative blood loss, the total number of lymph node dissected, the number of thoracic lymph node dissected, left recurrent laryngeal nerve lymph node dissection rate, the number of left recurrent laryngeal nerve lymph node dissected, left recurrent laryngeal nerve lymph node metastasis rate, right recurrent laryngeal nerve lymph node dissection rate, the number of right recurrent laryngeal nerve lymph node dissected, right recurrent laryngeal nerve lymph node metastasis rate were (306±56)minutes,200(100)mL, 29.9±13.1, 18.5±9.7, 78.47%(317/404), 4.0(3.0), 17.35%(55/317), 94.55%(382/404), 3.0(2.0), 21.20%(81/382). (2) Postoperative conditions. The tumor histopathological type (squamous cell carcinoma, neuroendocrine carcinoma, adenocarcinoma, carcinosarcoma, adenosquamous carcinoma, malignant melanoma), incidence rate of overall complications, cases with recurrent laryngeal nerve paralysis, cases with pulmonary complications, cases with anastomotic fistula, cases with incision infection, cases with chylothorax, cases with arrhythmia, cases with deep vein thrombosis, cases with other complications, incidence of re-admission to the intensive care unit, duration of postoperative hospital stay, 90-day mortality were 377, 11, 7, 5, 3, 1, 27.48%(111/404), 8.91%(36/404), 10.64%(43/404), 6.93%(28/404), 0.99%(4/404), 2.48%(10/404), 1.73%(7/404), 0.50%(2/404), 1.98%(8/404), 6.93%(28/404), 16(11)days, 0.50%(2/404). (3) Comparison of clinical features in patients who were admi-tted in different time periods. The number of patients who were admitted from June 2017 to May 2018, from June 2018 to May 2019, from June 2019 to May 2020, from June 2020 to May 2021, from June 2021 to June 2022 was 40, 56, 57, 116, 135, respectively. There were significant differences in age, tumor histopathological type, pT staging, neoadjuvant therapy, operation time, volume of intra-operative blood loss, the total number of lymph node dissected, the number of thoracic lymph node dissected, left recurrent laryngeal nerve lymph node dissection rate, the number of left recurrent laryngeal nerve lymph node dissected, the number of right recurrent laryngeal nerve lymph node dissected, incidence rate of overall complications among patients who were admitted in different time periods ( P<0.05). Conclusion:The Da Vinci robot-assisted superior mediastinum lymph node dissection around recurrent laryngeal nerve is safe and feasible, which can achieve good short-term efficacy.
