Hysterectomy is one of the most common gynecologic surgeries, with an increasing proportion of hysterectomies performed by a laparoscopic approach. Uterine manipulation is critical for patient safety and surgical efficiency; however, the most junior member of the surgical team assumes the responsibility of uterine manipulation, commonly without preparation. The objective of our study was to determine whether kinesthetic learning using a low-cost simulated pelvic model while learning the uterine manipulation maneuvers of a laparoscopic hysterectomy improves learning efficacy and application efficiency compared to an interactive video module alone.Our randomized control trial at an academic medical center included forty first-year and second-year medical students. Participants were randomized to the intervention group that used a low-cost simulated pelvic model for kinesthetic learning during the video module or the control group who only had the interactive video module to learn the uterine manipulation maneuvers of a laparoscopic hysterectomy.Participants in the intervention group were less likely to make unnecessary movements with demonstration of both pelvic side walls (right wall: control 78.9%, intervention 42.9%, p 0.027; left wall: control 94.7%, intervention 66.7%, p 0.046), and this was more pronounced in novice first-year participants (p 0.009). Additionally, participants in the intervention group reported higher perceived preparedness (100% versus 71.4% in control group, p 0.037). However, there was no difference in verbal or physical cues required, time per task, or force used between the groups.Kinesthetic practice may not be required for learning the uterine manipulation maneuvers of a laparoscopic hysterectomy, but it may be beneficial for more novice learners and to increase learners' perceived preparedness. Our novel interactive video module alone may be sufficient to prepare learners to perform uterine manipulation maneuvers prior to the operating room. |
