Abstract: Objective To analyzethe surgical outcomes of laparoscopic distal gastrectomy plus No. 8p lymphadenectomy. Methods 182 patients who underwent laparoscopic distal gastric cancer surgery in our department from July 2019 to March 2021 were selected and randomly divided into No. 8p group （89 cases） and conventional group （93 cases）. The differences in operation time, blood loss, number of lymph nodes detected and recent surgical complications between the two groups were compared, and the relationship between the number of lymph nodes detected in No. 8p group and other regions was further analyzed. Results There was no significant difference in operation time, blood loss and recent complications between the two groups （P>0.05）, but more operation time and lymph nodes were detected in the dissection group （P<0.05）. In the 89 patients in the No. 8p group, only 5 cases （5.6%） had lymph node metastasis. Further analysis of the relationship with the number of lymph nodes detected in other regions showed that there was a significant difference in the number of lymph nodes detected in No.12a groups （P<0.05）. Conclusion For laparoscopic distal radical gastrectomy, lymph node dissection in Group No. 8p is safe and feasible, and can improve the quality of lymph node dissection in groups No. 12a.
