Abstract:
Objective To observe the efficacy of D3 lymph node dissection of right colon on patients undergoing laparoscopic radical resection of right colon cancer.
Methods 199 patients with right colon cancer treated from October 2019 to January 2021 were selected for study. They were divided by the random number table method into D3 group（n=100 cases）and D2 group（n=99 cases）. Both groups received laparoscopic radical resection of right colon cancer，while group D3 underwent D3 lymph node dissection and group D2 underwent D2 lymph node dissection. SPSS 22.0 statistical software was used for data analysis. The measurement data of perioperative indexes were expressed by（
±
s），and independent
t test was used；the count data of postoperative complications were tested by
χ2 test，and the statistical significant difference was expressed by
P<0.05.
Results The number of lymph node dissection of patients in group D3 was more than that in group D2（P<0.05），the operation time，drainage time and hospitalization time in D3 group were longer than those in D2 group（P<0.05）；the incidence of complications in group D3 and D2 were 3.0% and 10.1% respectively. The incidence of complications in group D3 was lower than that in group D2（P<0.05）.
Conclusion D3 lymphadenectomy can significantly improve the efficacy of laparoscopic radical resection of right colon cancer，which is recommended to be popularized.
