An analplasty is a treatment for anal stenosis. Some patients may develop anal stenosis after multiple or extensive hemorrhoid and fissure surgeries. In these cases, an analplasty is performed along with a sphincterotomy. Studies show that extensive hemorrhoids are responsible for 90% of cases of anal stenosis. Both analplasty and medication are common treatments for anal stenosis. Medication alone suffices for the treatment of mild anal stenosis.
