Intrathecal or Extracapuslar Lymph Nodes Dissection For Patients With Rectal and Sigmoid Colon Cancer？

Abstract

Aim: To investigate that whether intrathecal lymph nodes dissection is superior to extracapsular lymph nodes dissection for patients with rectal and sigmoid colon cancer.Methods: We performed a retrospective clinical study between August, 2017 and October, 2019 at the department of general surgery, the affiliated hospital of Nanjing University Medical School. According to the ways of lymph nodes dissection, these patients were divided into extracapuslar group and intrathecal group. We then compared the curative effect and safety between the two groups.Results: A total of 211 patients were recruited in this retrospective study and assigned as follows: 62 cases to the intrathecal group and 149 patients to extracapuslar group. There were no statistic differences in the total number of lymph nodes, number of positive lymph nodes, and nodal staging between the two groups. However, the amount of bleeding in intrathecal group was significantly higher than that in extracapuslar group (p=0.000) and the operation time in intrathecal group was also significantly longer than that in extracapuslar group (p=0.000).Conclusion: Dissecting lymph nodes by extracapuslar dissection is preferred in radical resection of patients with rectal and sigmoid colon cancer. Statement: This paper compared the curative effect and safety between intrathecal and extracapsular lymph nodes dissection for patients with rectal and sigmoid colon cancer. This topic has never been reported in the literature and has great clinical significance.
