Abstract
Despite evidence that small bite closure is beneficial, it is not well documented how accurately and consistently surgeons employ this technique. We created a felt model to simulate fascial closure and educate residents regarding small bites. This study aims to gauge accuracy and consistency of bite size in fascial closure and assess if utilizing a templated model could improve technique. Two 10cm incisions were made in different pieces of felt. Residents were instructed to suture the incisions to simulate fascial closure by running the incisions closed with 1cm and 5mm bites respectively. The process was repeated with templated pieces of felt marking 1 and 0.5cm to guide bite size. Residents were timed for each closure. The travel and distance from the midline for each bite was measured and analysis performed. 14 residents participated. Paired T-test compared means and standard deviations of bite size. Taking 5mm bites took more time. Standard deviation of travel and right sided distance from midline were significantly smaller when a template was utilized. Standard deviation of travel as well as right sided distance was also improved when instructed to take 5mm bites. This study demonstrates that a small bite technique results more closure and that when residents are instructed to take smaller bites. The adage, "aim small, miss small," holds true in fascial closure and may be one reason why small bites improve hernia rates. This study also suggests that the use of a template improves accuracy and consistency of closure regardless of bite size intention.
