Treatment for rectal stricture (stricture of the rectum) is introduced as follows regarding this issue:
(1) Dilation therapy: Stenosis at the lower end of the rectum can be regularly dilated using fingers or a Hegar uterine dilator to gradually expand it.
(2) Surgical therapy:
① Rectal (wall) incision: A longitudinal incision of the scar tissue on the posterior wall of the stenotic part, followed by dilation treatment, or performing a longitudinal cut and horizontal suture on the posterior wall of the rectum. This method is mostly used for annular stenosis.
② Partial rectal resection with sphincter preservation: Used for tubular stenosis, select partial rectal resection and anastomosis or rectal pull-through resection based on the height and range of the stenosis location.
③ Colostomy: For rectal stenosis combined with intestinal obstruction, internal fistula, and severe infection around the rectum, a temporary transverse colostomy may be required. After the condition is controlled, further surgery can be performed to treat the stenosis.
