Abstract：Objective To investigate the application effect of targeted lymphadenectomy in patients undergoing laparoscopic radical gastrectomy.Methods Eighty-six patients who underwent laparoscopic radical gastrectomy in our hospital from March 2016 to March 2019 were selected as the subjects.According to simple randomization, they were divided into directional group (43 cases) and conventional group (43 cases).Patients in the directional group were treated with targeted lymphadenectomy, and patients in the conventional group were treated with conventional lymphadenectomy.The surgical indexes of the two groups were compared, and the micrometastases in the blood and abdominal cavity of the two groups were observed.Results The operation time and postoperative hospitalization time of the directional group were shorter than those of the conventional group, the intraoperative blood loss was less than that of the conventional group, and the differences were statistically significant (P＜0.05).The postoperative micrometastasis rates of blood and abdominal cavity in the directional group were lower than those of the conventional group, and the differences were statistically significant (P＜0.05).There were no significant differences between the two groups in the way of anastomosis, the number of lymphadenectomy, the distance between the margin and the tumor, and the time of anal exhaust (P＞0.05).There were no significant differences in preoperative micrometastasis rates of blood and abdominal cavity between the two groups (P＞0.05).There were no significant differences in micrometastasis rates of blood and abdominal cavity in the directional group before and after opration (P＞0.05).Conclusion Targeted lymphadenectomy in laparoscopic radical gastrectomy can not only shorten the operation time, reduce the amount of bleeding, but also reduce the risk of recurrence by reducing the risk of micrometastasis.
