Single-port access systems, used to perform endoscopic surgery through a single incision, are currently used in many human and veterinary surgeries. These systems present some technical challenges as they offer limited space for manipulation. No objective study has evaluated the degree of possible movement within different single-port access systems. This study aimed to measure and compare the possible movements of the endoscope and instruments within three single-port access systems: the Covidien SILS-port, Storz Endocone, and glove port. The glove port consists of a surgical glove and an O-ring retractor. A clear acrylic box with artificial skin was used to mimic the abdominal wall and cavity. A motion capture system with 18 cameras was used to trace the possible movements of the endoscope. The volume of the cone-shaped three-dimensional figure described by the scope when circled 360° was used to compare maneuverability across the three systems. The glove port showed higher maneuverability than the two commercially available ports when an endoscope alone, or an endoscope and instrument, was or were inserted. A higher degree of maneuverability is positively associated with easier handling of the endoscope and instruments during surgical procedures. The findings of this study may benefit students and young professionals by helping them to select an easy-to-use single-port access system when beginning single-incision endoscopic surgery.
