Figure 3 Schematic presentation of the surgical procedure. A: A magnet is inserted through the anus into the proximal portion of the colon; B: Another magnet is inserted through the anus to the distal end of the colon; C: The two magnets in the colon are attracted; D: The magnets enter the rectum after a side-to-side colonic anastomosis is established.
