Core Tip

Core Tip: Magnetic compression anastomosis (MCA) is a new anastomosis approach that differs from suture and staple anastomosis. Multiple studies have demonstrated the feasibility of MCA in the digestive tract, but whether MCA establishment is affected by the shape of the magnets has not been determined. In this study, the effect of differently shaped magnets was examined in a rat model of side-to-side colonic anastomosis. The results showed no significant difference in the establishment of side-to-side colonic anastomosis with the use of circular vs cylindrical magnets. Moreover, the findings of this study support Yan-Zhang's Peripheral Decision Theory of digestive tract MCA.
