Abstract 【Objective】To investigate the factors influencing the number of lymph nodes detected after laparoscopic radical resection of rectal cancer.【Methods】Clinical data of 87 patients with rectal cancer undergoing laparoscopic radical resection of rectal cancer from February 2016 to March 2017 were selected. According to whether the patients received neoadjuvant therapy (including radiotherapy and chemotherapy) before operation, they were divided into neo-adjuvant therapy group and non-neoadjuvant treatment group. All kinds of clinicopathological factors which may affect the number of lymph nodes detected were analyzed.【Results】The maximum diameter of the tumor, the length of the specimen, the depth of tumor invasion and the number of lymph nodes detected by the operation were significantly correlated, the difference was statistically significant (P<0.05). However, sex, age, tumor location, pathological type, tumor differentiation, TNM staging, preoperative CEA and surgical procedure had no correlation with the number of lymph nodes detected (P>0.05). The average number of total lymph nodes in the non neoadjuvant therapy group, the average number of intestinal lymph nodes and the number of mesenteric lymph nodes were significantly higher than those in the neoadjuvant therapy group, the difference was statistically significant (P<0.001). The maximum diameter of the tumor, the length of the specimen, the depth of tumor invasion, and whether the neoadjuvant therapy was accepted or not were independent factors affecting the number of lymph nodes more than 12.【Conclusion】The maximum diameter of tumor, the length of specimen, and the depth of tumor invasion were related to the number of lymph nodes detected in rectal cancer patients. Patients with minimal tumor diameter, small specimen length, low depth of tumor infiltration, and preoperative neoadjuvant therapy are more likely to detect 12 lymph nodes in postoperative specimens.
