Treatment of postoperative anastomotic stenosis for colorectal cancer is often challenging, especially for patients who do not respond well to endoscopy. In cases where patients have undergone an enterostomy, the stenosis can be easily resolved through magnetic compression. However, common magnetic compre
We here report the case of a 57-year-old woman who had undergone a laparoscopic radical rectum resection (Dixon) for rectal cancer. However, she started facing difficulty in defecation 6 months after surgery. Her colonoscopy indicated stenosis of the rectal anastomosis. Endoscopic balloon dilation was performed six times on her. However, the stenosis still showed a trend of gradual aggravation. Because the patient did not undergo an enterostomy, the conventional endoscopic magnetic compression technique could not be performed. Hence, we imple
The Y–Z DMR deformable magnetic ring is an excellent treatment strategy for patients with rectal stenosis and without enterostomy.
Core Tip: The magnetic compression technique can be used to treat patients with rectal stenosis that have also undergone an enterostomy. However, the existing magnetic ring cannot be used in patients without enterostomy. We designed a Y–Z deformable magnetic ring (Y–Z DMR), which can realize the single channel of the magnet placed through the anus. This paper reports the first successful clinical case of using the Y–Z DMR for the treatment of rectal stenosis.
