What is the effective treatment for colonic stenosis?

Patients should pay attention to how colon stenosis should be treated. The most common treatment method is drug therapy. You can use potassium permanganate warm water sitz bath or enema, or take liquid paraffin or suppositories externally to help defecation.

1. Drug treatment includes warm potassium permanganate bath or enema, oral liquid paraffin, external suppositories, enemas, etc. to make bowel movements smooth. If there are shallow fissures or ulcers, 10% silver nitrate can be used for rubbing or external application of ointment.

2. Dilation method: For mild stenosis after surgery or injury, dilation can be used to treat it. Use fingers or dilators to dilate once a day or 1 to 2 times a week. Gradually increase the diameter of the dilator and extend the dilation interval. It is also applicable to annular rectal stenosis caused by lymphogranuloma venerealis.

3. For severe stenosis and long-term stenosis with hard scars, dilation can sometimes be temporarily effective, but it is prone to recurrence. The surgical method varies according to the condition of the lesion, the degree of stenosis or the location of the stenosis. Commonly used methods include scar removal or sphincter incision, such as linear incision behind the anal canal, posterior rectal incision, internal rectal incision, and various plastic surgeries such as anoplasty and anal canalplasty. For high rectal stenosis, a combined abdominal perineal resection of the rectum with preservation of the anus and sphincter can also be considered. For acute complete intestinal obstruction caused by chronic obstruction, physical weakness or stenosis, colostomy can be considered to divert feces, allow the rectum to rest and relieve self-poisoning symptoms, and then perform secondary incision or colostomy after the patient recovers. Anorectal stenosis caused by a tumor should be treated as a tumor.
