To investigate the safety and feasibility of single-port + 1-port (SILS+ 1) laparoscopic radical resection of distal gastric cancer.

Clinical data of 41 patients with SILS+ 1 laparoscopic radical resection of distal gastric cancer admitted from January 2019 to December 2019 were retrospectively analyzed, who were assigned to the SILS+ 1 group. Clinical data of 68 patients who received five-hole laparoscopic radical resection of distal gastric cancer from January to December 2018 were included for comparison, and they were assigned to the five-hole group. Statistical software SPSS 24.0 was used for data analysis, operation related indicators, VAS score and other measurement data were expressed by (±s), independent sample t-test was used for comparison between groups. Postoperative complications were tested by χ² test. P<0.05 was statistically significant.

The operation time of the SILS+ 1 group was slightly longer than that of the Five hole group, postoperative abdominal drainage tube extraction time and hospitalization time were shorter than those of the Five hole group, and the differences between the two groups were statistically significant (P<0.05); There were no significant differences in intraoperative blood loss, number of lymph node dissection and hospitalization cost between 2 groups (P>0.05). The total incidence of postoperative complications was 4.9% in the SILS+ 1 group and 5.9% in the Five hole group group. The VAS scores of SILS+ 1 group at 12 h, 1 d, 2 d and 3 d after surgery were significantly lower than those of the five-well group, with statistical significance (P<0.05).

Compared with the five-hole method, it is safe and feasible to perform SILS+ 1 laparoscopic radical resection of distal gastric cancer under abundant laparoscopic operation techniques.
