Comparison of a single-access glove port with a SILS™ port in a surgical simulator model using MISTELS

Background Recent advances in laparoscopy both in human and veterinary medicine have looked at means of being less invasive by using single-port access surgery as opposed to multiport access surgery. The glove port has gained popularity as a cost-effective alternative to commercially available single-port access devices. The primary aim of this study was to compare the glove port to the SILS[TM] port in a simulator model using the first two MISTELS (McGill inanimate system for training and evaluation of laparoscopic skills) tasks (peg transfer and pattern cutting). Methods Twenty-two novices were enrolled in this experimental study. Each participant had 60 min to practise both MISTELS tasks using two-port laparoscopy. Thereafter participants performed both tasks using the glove and SILS[TM] port with scores being calculated based on task completion time and errors. Higher scores were indicative of better performance. Participants were assigned into two groups with the starting order of the single ports being randomly selected. A self-evaluation questionnaire with three questions was completed by each participant after testing, rating each port. Results Significantly (p < 0.05) higher scores were achieved using the glove port compared to the SILS[TM] port when performing both tasks. The glove port was subjectively evaluated as easier to use with more manoeuvrability of the instruments than the SILS[TM] port. Implications of the study The glove port's improved manoeuvrability and ease of use make it a cost-effective alternative to the SILS[TM] port, for use in single-port laparoscopic veterinary surgery.
