Abstract:
Objective To investigate the clinical effect of Delta anastomosis，end-to-end puncture anastomosis and Overlap anastomosis in laparoscopic pylorus-preserving gastrectomy（LAPPG）.
Methods The clinical data of 90 patients with early gastric cancer who received LAPPG from January 2018 to June 2021 were retrospectively analyzed. According to the different reconstruction methods of digestive tract，the patients were divided into group A（Delta anastomosis），group B（Overlap anastomosis）and group C（end-to-end anastomosis by puncture），with 30 cases in each group. SPSS 24.0 was used for data analysis. Perioperative indicators and nutritional indicators were expressed by（
±
s）.
One-way ANOVA was used for comparison between groups，and independent sample t-test was used for pairwise comparison between groups. Nutrition indexes at different time points were analyzed by repeated measures
ANOVA. Postoperative complications and other counting data were analyzed by
χ2 test.
P<0.05 was considered statistically significant.
Results The postoperative anal recovery time and hospital stay of group A were longer than those of group C（P<0.05）. There were no significant differences in operation time，anastomosis time，intraoperative blood loss and postoperative residual stomach volume among the three groups（P>0.05）. There was no significant difference in the total incidence of postoperative complications among the three groups（P>0.05）. The white blood cell count on the 3rd and 7th day after operation was higher than that before operation，and the serum albumin and hemoglobin were lower than those before operation（P<0.05）. Compared among the three groups，the serum albumin and hemoglobin levels in group C were higher than those in groups A and B on the 3rd and 7th day after operation（P<0.05）.
Conclusion End to end anastomosis by puncture in laparoscopic pylorus-sparing gastrectomy has the advantages of safe，feasible，quick postoperative recovery and short hospital stay，which is worthy of clinical application.
