Comparative study of cylindrical vs circular ring magnets for colonic anastomosis in rats

Figure 3 Surgical procedure. A: For the cylindrical group, a cylindrical daughter magnet (DM) and cylindrical parent magnet (PM) were placed in the proximal and the distal end of the colon (black arrows); B: The two cylindrical magnets attracted together (yellow circle); C: For the circular group, a circular ring-DM and circular ring-PM were placed in the proximal and distal ends of the colon (black arrows); D: The two circular ring magnets attracted together (yellow circle); E: For the cylindrical–circular group, a cylindrical-DM and a circular ring-PM were placed in the proximal and distal ends of the colon, respectively (black arrows); F: The cylindrical-DM and circular ring-PM attracted together (yellow circle). DM: Daughter magnet; PM: Parent magnet.
