Abstract: Objective To investigate the safety,cancer radical and early efficacy after laparoscopic gastric cancer resection D2.Methods Seventy-two cases of gastric cancer patients were randomly divided into two groups according to the admission order,each group 36 cases.The control group was given traditional open gastric resection,while the observation group took laparoscopic gastric D2 resection.The early efficacy,tumor radical and surgical safety of two groups were compared.Results The operation time of observation group was significantly longer than that of control group.The incision length,blood loss,recovery time of gastrointestinal function,ambulation,and the average hospital stay time of observation group were significantly less than those of control group(P <0.05 or <0.01).The number of lymphadenectomy,the length of near and far cutting edge showed no significant difference between two groups(P >0.05).The postoperative complication rate of observation group 11.11%(4/36)was significantly lower than that of control group 27.78%(10/36)(P <0.05).Conclusion Laparoscopic gastric D2 resection has good early effect,safe and small surgical trauma,which are conducive to the recovery of patients,the method has good clinical application value.
