| Popis: | We developed a system to objectively verify the endoscopic surgical skills of pediatric surgeons.We developed a thoracoscopic model of congenital diaphragmatic hernia mimicking a newborn's size. The examinees were divided into Experts (n = 10) and Trainees (n = 19), and each group performed two tasks (Task 1, reduction of a herniated intestine from the thoracic space to the abdomen; Task 2, perform three suture ligatures of a diaphragm defect using intracorporeal knot-tying). The end points were the time required to complete Task 1, time score calculated using the residual time from the time limit for Task 2, number of complete full-thickness sutures, maximum air-pressure tolerance, degree of diaphragm deformation, and the residual defect areas after suturing. We also evaluated the total path length and velocity of the forceps tips using a three-dimensional position measurement instrument.The Experts had significantly superior results for the time for Task 1, time score, number of complete full-thickness sutures, maximum air-pressure tolerance, and degree of diaphragm deformation in Task 2 (all P.05). We found that the total path length and average velocities for the left forceps were inferior to those of the right forceps in both tasks in the Trainees (both P.05, respectively), whereas the Expert group showed no significant laterality in these tasks.Our model could validate the quality of endoscopic surgical skills and could differentiate between Expert and Trainee pediatric surgeons. The Experts could use their forceps equally well to perform tasks even in a small working space. |
