Abstract

There is a need for suitable non-clinical teaching models in undergraduate medical education.This study was undertaken to demonstrate the feasibility of using an animal model to teach surgical skills to medical students.Two gastrotomies were created in each pig, and then closed using stapled and hand-sewn techniques.Animals were sacrificed seven days later and the closures examined grossly and histologically.<BR>1) Medical students, as surgeons with minimal experience, are able to significantly reduce the time needed to perform closure of a gastrotomy in a porcine model using surgical staplers compared to a hand-sewn closure.<BR>2) Medical students can perform advanced abdominal surgery techniques with adequate instruction resulting in excellent surgical outcomes in a porcine model.<BR>3) The porcine model is a valuable tool to teach animal ethics as well as basic surgical techniques in the non-clinical environment and may help to increase interest among students in a surgical career.
