Anorectal fistula treatment
An anorectal fistula is a small-diameter, communicating tunnel varying in length that develops due to an infection in the tissues surrounding the rectum.
How Is the Surgery Performed?
A particular surgical approach is tailored individually after assessing the openings of the fistula tract, the involvement of the anal sphincter, and the depth of the fistula.
An anorectal fistula is usually treated under spinal anesthesia. Time in surgery depends on the method of surgical treatment and can take from 30 minutes to 1 hour.
If the fistula tract does not involve the anal sphincter, the fistula is excised.
The treatment of deep fistulas or fistulas that involve the anal sphincter may require the placement of a special surgical thread (seton). This treatment method prevents a large scar and undesirable complications. During the surgery, the cutting seton is passed through the fistula tract. The seton is tied in a loop that is gradually tightened during several subsequent procedures until the complete excision of the entire fistula tract.
What Should be Known After Surgery?
- Until the wound heals completely, special antiseptic ointments or solution should be used after every bowel movement;
- The patient should avoid constipation, and it is recommended to use laxative medications if needed.
