To investigate the perioperative efficacy and safety of complete radical laparoscopic, laparoscopic, and open radical surgery for advanced gastric cancer.

120 cases of advanced gastric cancer treated in our hospital from March 2013 to March 2015 were retrospectively analyzed. According to the different operative methods, they were divided into three groups: complete laparoscopic group, laparoscopic group, and open group, with 40 cases in each group. SPSS20.0 software was used to statistically analyze. The perioperative efficacy-related indicators and other measurement data were described in the form of(±s), and compared with t tests between the two groups, and F tests among the three groups. Postoperative complications and recurrence within 1 year after follow-up were performed. Counting data such as metastasis, survival, etc. were analyzed using the χ² test. When P<0.05, the difference was statistically significant.

There was no significant difference in lymph node dissection and operation time between complete laparoscopic group, laparoscopic group and laparotomy group (P>0.05). The intraoperative blood loss, postoperative analgesia time, and postoperative hospital stay in the complete laparoscopic group were significantly lower than those in the open group (P<0.05), but there was no significant difference between the complete laparoscopic group and the laparoscopic group (P>0.05). The postoperative bedtime and gastrointestinal reconstruction time in the complete laparoscopic group were significantly lower than those in the open group and laparoscopic group (P<0.05). There were no significant differences in the incidence of postoperative complications among the three groups (P>0.05). There was no significant difference in the recurrence, metastasis and death among the three groups within one year (P>0.05).

Complete laparoscopic radical gastrectomy has the advantages of rapid recovery, less trauma, less pain, and safety and reliability. The recent curative effect is better. It is worth further promotion and application.
