To explore the safety and feasibility of total laparoscopic anastomosis in laparoscopic radical gastrectomy.

96 cases treated in our hospital with laparoscopic radical gastrectomy from January 2017 to January 2019 was retrospectively analyzed. They were divided into two groups according to the different surgical methods, 48 in each group. The control group was treated with small incision assisted anastomosis, and the experimental group was treated with total laparoscopic anastomosis. Statistical analysis was performed on the data using SPSS 23.0 software. The intraoperative data of the two groups were indicated as(±s), and compared with independent t test. The postoperative complication rate and pain degree were compared by χ² test. P<0.05 was considered statistically significant.

The length of the incision in the experimental group was (2.47±0.38) cm, and the anastomosis time was (26.34±4.21) min, which was significantly shorter than the incision length (7.26±1.03) cm and the anastomosis time (70.15±20.34) min of the control group (P<0.05). The mild pain rate of the experimental group was 68.75%, which was significantly higher than that of the control group of 35.42%. The severe pain was 12.50%, which was significantly lower than that of the control group of 43.75% (P<0.05). The total postoperative complication rate of the experimental group was 6.25%, which was significantly lower than the control group of 27.08% (P<0.05).

Compared with the conventional small incision assisted anastomosis technique, the laparoscopic anastomosis technique has the characteristics of smaller incision and shorter anastomosis time in laparoscopic radical gastrectomy. The postoperative pain is mild and the postoperative complication rate is less.
