The evaluation of the correlation between origami crane training and Fundamentals of Laparoscopic Surgery (FLS)

How does making origami cranes under a dry box affect Fundamentals of Laparoscopic Surgery (FLS) scores in medical students?Four medical students from Asahikawa Medical University (tertiary hospital) participated. They made origami cranes under a dry box (origami crane training) five days per week for four weeks. The time required to make each origami crane (origami crane time) and degree of completion were evaluated. FLS scores were measured before training and on days 5, 10, 15, and 20. We examined the relationship between "origami crane training" and FLS scores.At the beginning of the experiment, none of the participants could complete the origami crane, but they were able to complete it in 31 ± 7 min on day 20. The Total FLS score was 164 ± 48 before the start of training, and 1107 ± 112 on day 20. The average scores of the students closely approached the Proficiency Level for the FLS tasks of peg transfer, loop ligation and extracorporeal ligation (103→228, 61→137, 0→259). The change over time in the average of the increase in Total FLS Score (difference from the first time and each week's score) improved significantly in four weeks (P < 0.01).Origami crane training improved the medical students' FLS scores. We thought that origami crane training mainly enhanced hand-eye coordination and bi-hand coordination.
