Efficacy of a Self-timed Trial of Laparoscopic Surgical Training Using a Dry Box.

This study evaluated the self-timed trial training for laparoscopic suturing. The set task involved grasping the suture, aligning the needle with a needle holder, passing the suture, making 3 knots, holding the 2 tails of the suture with one grasper, and cutting them. Trainees were given an instruction for suturing and reducing their suturing time. The same instruction was given 3 months later. Suturing times for the first and second trials and the last trial after the second instruction of the 9 trainees were measured. Their mean suturing times were statistically significantly shorter after instruction (before instruction: 276.7 ± 43.4 seconds, after instruction: 177.4 ± 46.1 seconds; = .0035). Four trainees were trained twice during the second instruction. Their suturing times were shorter than those of the other trainees, and the standard deviation decreased (120.5 ± 21.2 seconds, = .017). A self-timed trial training for laparoscopic suturing using a dry box makes training interesting and motivates trainees.
