Abstract
Objective
Analyze the learning curve of medical students when they are trained with a laparoscopic box trainer and are presented with different modes of real-time feedback on their performance in the laparoscopic suturing procedure.
Design
A prospective randomized controlled trial (RTC) was performed. Three groups were proposed: control, visual, and haptic. The block randomization technique was used to assign the participants to one of the three groups. Each group trained the intracorporeal square flat knot task in a standardized FLS box simulator. A total of 11 sessions were programmed for this study: a pre-training session, eight training sessions, a post-training session, and a follow-up session. Measurement of the generated reaction force during the task were taken weekly for the first 10 sessions (pre-training, training, and post-training); then, the follow-up measurement was taken a month after.
Setting
This study was carried out in a single center at the Unidad de Simulación de Posgrado (USIP) of the postgraduate medicine program of the Universidad Nacional Autónoma de México (UNAM) between May and August 2023.
Participants
The eligible participants were medical students without experience in minimally invasive surgery. All social service intern medics doing their social service in the USIP were invited to participate. A total of 20 participants entered the study from which 18 of them finished all the programmed sessions.
Results
A total of ten metrics were extracted from the reaction force signal measured at each session. All metrics are directly proportional to the reaction force and low magnitudes imply high tissue-handling proficiency. All groups improved their tissue handling skills, being the visual group the one who achieved better performance, followed by the haptic group and lastly the control group.
Conclusion
The use of real time feedback, especially visual feedback can help novices to shorten the learning process of tissue handling and achieve a better proficiency in advanced tasks in shorter training periods.

The Journal of Surgical Education (JSE) is dedicated to advancing the field of surgical education through original research. The journal publishes research articles in all surgical disciplines on topics relative to the education of surgical students, residents, and fellows, as well as practicing surgeons. Our readers look to JSE for timely, innovative research findings from the international surgical education community. As the official journal of the Association of Program Directors in Surgery (APDS), JSE publishes the proceedings of the annual APDS meeting held during Surgery Education Week.
