Development of Laparoscopic Training Protocol Using Small Animal Model in Urology / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Laparoscopy is a standard treatment for many diseases. We developed a laparoscopy training protocol that provides a learning experience equivalent to that of an animal laboratory based laparoscopic training course. We proved that the rabbit can be used as an appropriate model for a laparoscopy training program. MATERIALS AND METHODS: Three operators undertook laparoscopic procedures on 15 rabbits using our developed protocol. We checked both objective and subjective parameters, such as operation times and complications for the former, and hand-eye coordination, tactile sensation, tool handling and total skill difficulty for the later, using visual analogue scores. RESULTS: For the first 5 rabbits, the mean operative times (min.) for the 3 operators were 41, 48 and 46.2 for a simple nephrectomy (SN), 62, 68.2 and 66.2 for a partial nephrectomy (PN), 28.8, 36 and 31.8 for an adrenalectomy (Ax) and 65.4, 69 and 60.6 for a simple cystectomy (SC). For the second 5 rabbits the mean operative times (min.) were; SN 32.2, 46.2 and 40.2, PN 57.8, 66.2 and 61.8, Ax 22.8, 32.6 and 32 and SC 65.4, 64.2 and 57.4. For all 15 rabbits the mean operative times (min.) were; SN 20.6, 35.4 and 30, PN 48.6, 54.6 and 53.4, Ax 15.8, 26.2 and 26.2 and CS 48.2, 53.6 and 47.6. CONCLUSIONS: Our laparoscopic training model, using a small animal, provides practicing urologist with the concepts of laparoscopy concept. The rabbit model is appropriate for addressing laparoscopic procedures, with economic benefits. Based on this model, it would be possible for residents to familiarize themselves with laparoscopic procedures.
