Abstract    Objective    To investigate the feasibility and training effects of a domestically produced 3D laparoscope in basic laparoscopic surgical skills training for residents. Methods    A total of 35 surgical residents who received the first-stage course of advanced integrated two-stage laparoscopic simulation training in our hospital from December 2019 to December 2021 were prospectively enrolled as the research participants. The trainees operated a conventional 2D laparoscope and a domestic 3D laparoscope respectively. A questionnaire was used to collect their subjective perceptions of 3D laparoscopes. After the training, the operation assessment results of the basic skills training were evaluated. Results    The results of the subjective questionnaire showed that the trainees had certain visual discomfort such as eye fatigue and vertigo during the training process for 3D laparoscope, but there was no obvious discomfort in the overall subjective experience of 3D laparoscope. 3D laparoscope was significantly better than 2D laparoscope in terms of depth (77.1%), clarity (62.9%), and spatial orientation (80%). The trainees performed 3D and 2D laparoscopes respectively to complete the assessment of three modules: one track transfer, one tunnel pass, and high and low pillars. There was no significant difference between the objective assessment results of the 3D laparoscope group and the 2D laparoscope group in terms of time spent ［(286.6±215.2)s vs. (302.3±249.2)s, (280.1±157.1)s vs.(306.3±248.4)s, (317.2±130.2)s vs. (342.0±283.7)s］, a number of irregularities(2.3±1.8 vs. 2.7±3.3, 2.6±2.0 vs. 3.1±4.3, 7.0±3.8 vs. 6.0±9.5)and scores(3.6±0.9 vs. 3.5±0.9, 3.7±0.9 vs. 3.6±0.9, 3.6±0.9 vs. 3.7±1.0) (P>0.05). Conclusion    Domestically produced 3D laparoscopes are effective and feasible in basic laparoscopic surgical skills training, with good subjective acceptance by trainees, and can be used as adjunct training before using 3D laparoscopes in clinical work and promote the clinical application of 3D laparoscopes.
