Abstract:Objective To verify the feasibility of self-designed and processed magnamosis ring in the reconstruction of esophagogastric anastomosis through animal experiments. Methods In 10 male New Zealand rabbits, the junction of esophagus and cardia was transected. The parent magnetic ring was placed at the end of the esophagus and ligated on the catheter of the parent magnetic ring. The daughter magnetic ring was inserted into the stomach through the cardia, and the parent magnetic ring and the daughter magnetic ring attracted and coupled each other. After 10-14 days, the magnetic ring was detached into the stomach and esophagogastric anastomosis was established. Esophagogastric anastomotic specimens were obtained 1 month after the operation, and the anastomotic healing was observed with the naked eyes. Results Esophagogastric magnamosis was successfully completed in all experimental animals, with an average anastomosis time of (10.50±1.58)min and the time of anastomosis establishment (10.70±3.49) d. The survival rate of all experimental animals at 1 month after operation was 100% . Anastomotic specimens were obtained 1 month after the operation, and macroscopic observation showed that the mucosa of the anastomosis was continuous and there was no stenosis at the anastomotic site. Conclusion Magnamosis has the advantages of simple operation, safe and reliable anastomosis in esophagogastric anastomosis, and has the potential for clinical application.
