Abstract: Objective　To investigate the effect of laparoscopic team training on residents' practical skills training.Methods　A total of 84 residents from April 2022 to December 2023 were randomly assigned to three groups: experimental group 1 (E1, n=26), in which team training was emphasised for the first 4 weeks and individual training for the next 4 weeks; experimental group 2 (E2, n=30), in which individual training was emphasised for the first 4 weeks and team training for the next 4 weeks; and control (c) group (n=28), which followed a traditional training model with an emphasis on individual training throughout. Basic skills tests in object transfer, cutting and dissection, and suturing and knot tying were performed after the 4th and 8th weeks of training to compare the performance of the three groups in the three basic laparoscopic skills tests. In addition, a team satisfaction survey was administered to the E1 and E2 groups after the completion of all training to assess their satisfaction with the team simulation training. Statistical analysis was performed using SPSS 25.0 software with one-way ANOVA and Kruskal-Wallis H-test.Results　The test scores of the three basic skills for the E1 and E2 groups were significantly better than those of the C group, with statistical significance (P＜0.05). E1 group outperformed the C group in all three basic skills tests. In the second period, E2 group performed better than the C group in both the shear separation and tying knot tests, with statistical significance (P＜0.05).Conclusion　Laparoscopic team simulation training conducted at different time intervals is effective for residents' training. As an innovative training method, it can improve residents' performance and satisfaction in basic laparoscopic skills.
