Introduction: Previous studies have suggested that training box and suture workshop can improve doctors’ performance during real laparoscopic procedures. Our study was carried out to provide a practical model of laparoscopic training programme, based on the concept of entrustable professional activities (EPAs) to build competency-based clinical workplace curricula. Methods: Thirty surgical residents with limited laparoscopic experience performed 10 repetitions of 3 tasks (Bean Drop, Running String and Suture Foam (Endostitch) with standardized distribution of practice in a bench-top laparoscopic box trainer. Pre-training and post-training questionnaires were used to assess their knowledge about sutures and their perceptions about the workshop. Results: Five learning curve patterns were determined based on performance differences and confidence level for the completion of basic laparoscopic technical skills workshop. The majority of junior physicians showed significant improvement on performance and confidence level while senior resident physicians showed no tendency of skills and confidence level improvement. Conclusions: There is a clear and direct relationship between the skill and confidence level of laparoscopic suturing skills and years for resident training. Laparoscopic training box can efficiently reinforce formal training to overcome the lack of exposure to laparoscopic procedures as primary surgeons. We believe that promoting suture workshops as a routine for junior residents or even medical students to foster more skillful surgeons is an important issue that should be addressed in future research.
