Abstract
BACKGROUND: Mastering laparoscopic suturing, a critical aspect of minimally invasive surgery, remains a challenge. Self-assessment and 'reflection before practice' may enhance the learning curve of laparoscopic suturing. This study investigates the optimal frequency of self-assessment and reflection before practice in laparoscopic suturing training. METHODS: Participants (medical students, surgical residents, and medical PhD students) underwent laparoscopic suturing training at home using a laparoscopic simulator (LaparoscopyBoxx). Three groups were formed: a 'control group' without self-assessment, a 'periodic self-assessment group', and a 'continuous self-assessment group'. The validated Laparoscopic Suturing Competency Assessment Tool (LS-CAT) served as self-assessment form. Participant's performance was quantified by objective parameters (time, distance, handedness, off-screen time, speed, acceleration, smoothness and distance between the instruments) measured by SurgTrac software. RESULTS: No significant differences were observed between groups for primary outcome parameters time and distance across tests. However, significant differences emerged in secondary outcome parameters off-screen (baseline-test, p = 0.018), acceleration (baseline-test, p = 0.007), smoothness (baseline-test, p = 0.004; after-test, p = 0.038) and speed (after-test, p = 0.033) at various tests, favoring the self-assessment groups. CONCLUSION: Self-assessment and reflection before practice may lead to more efficient instrument utilization and increased safety. A lower frequency of self-assessment and reflection before practice offered comparable benefits, which optimizes training efficiency, and is therefore recommended.
