Operational process. (A) Rectography demonstrating rectal stenosis. (B) The “S”-shaped magnetic ring was inserted into the distal rectum. (C) The “S”-shaped magnetic ring was inserted into the proximal rectum. (D,E) The “S”-shaped magnetic ring during deformation. (F) The magnetic ring in the proximal rectum was completely transformed into an “O”-shape. (G) A distal magnetic ring was placed transanally. (H) The magnets at both ends of the rectal stenosis attracted to each other.
