Core Tip
Core Tip: We designed a deformable self-assembling magnetic anastomosis ring (DSAMAR) that can pass through a severely narrow digestive tract, to facilitate magnetic compression anastomosis reconstruction of the digestive tract under endoscopy. We set up two control groups, the common magnetic ring group and the manual suture group, to analyze the anastomotic effect of gastric bypass anastomosis with the DSAMAR. The results showed that the anastomosis effect achieved with the DSAMAR was similar to that in the common magnetic ring group and better than that in the hand-sewn group. This study lays a solid foundation for further clinical application of the DSAMAR.
