title: Scientific assessment of endoscopic surgical skills.
abstract: Recently, significant attention has been focused on training and education for safe endoscopic surgery. A new assessment method, the Hiroshima University Endoscopic Surgical Assessment Device (HUESAD), has been designed at Hiroshima University to evaluate the smoothness of the movement of endoscopic instruments from velocity. Experts (with experience in performing more than 100 laparoscopic surgeries) and novices (with no experience in performing laparoscopic surgery) were recruited for this study. The aim of task 1 was to move the tip of the endoscopic instrument on the tops of poles from A to C, and task 2 was to move it from the right pole B to the left pole D. The peak velocity (Vp) and the time when peak velocity appears (Tp) were analyzed. Both the peak velocity (Vp) and the time when peak velocity appears (Tp) to perform task 1 and task 2 were significantly faster in the expert group than in the novice group. The peak velocity (Vp) and the time when peak velocity appears (Tp) in HUESAD, which indicate the smoothnes of the endoscopic procedure, are among the most important factors for assessing endoscopic surgical skills.
