Novel magnetic compression technique for the treatment of postoperative anastomotic stenosis in rectal cancer: A case report

Figure 1 Preoperative examination. A: Colonoscopy image showing the stenosis; B: Colonography.

Figure 2 Schematic illustration of the surgical plan. Zebra guide wire was inserted through the ileostomy and pulled out through the anus with the assistance of colonoscopy. The daughter magnet and parent magnets were inserted into the two sides of the rectum stenosis along the zebra guide wire through the ileostomy and the anus, respectively.
