Core Tip

Core Tip: Magnetic compression anastomosis, which is a new type of anastomosis, has been extensively studied in digestive tract anastomosis in animals and humans. Previous studies have focused on the feasibility and safety of different magnetic designs for gastrointestinal anastomosis. Moreover, some scholars have proposed the hypothesis that magnetic force may affect the anastomosis effect. In this study, two groups of magnets matched for shape and size but with different magnetic forces were used in colonic side-to-side anastomosis experiments. The findings demonstrated that magnetic force in the range of 4.10-8.26 N did not affect the colonic side-to-side anastomosis.
