Abstract: Objective To investigate the effect of laparoscopic simulators in surgical residency training. Methods 10 residents who have 3 years clinical working experiences without Laparoscopic experience were selected and trained for 4 weeks in laparoscopic simulator, practicing clipping beans, cutting paper, suturing and knotting, respectively examined at the time of pre-training, training after 2 weeks and after 4 weeks. The exam results were statistically analyzed. Results The scores in clipping bean, cutting paper, suturing and knotting both 2 weeks of training and 4 weeks of training were signifi cantly higher than that of pre-training (P < 0. 05). The score of cutting paper after 4 weeks of training was signifi cantly increased more than that of 2 weeks of training (P < 0. 05), but there were no statistical differences of clipping bean and suturing and knotting between 2 weeks of training and 4 weeks of training (P > 0. 05). Conclusion The laparoscopic training simulator for beginners is feasible and effective which can rapidly improve their laparoscopic operation skills and also lay a foundation for laparoscopic surgery.
