If PPH treatment is taken for hemorrhoids, if postoperative anal stenosis occurs, different methods should be selected according to the severity of the condition. For the mild early stage, treatment can be carried out by local massage or regular anal dilation, especially in the early postoperative stage hemorrhoid cream or anti-inflammatory ointment should be applied to prevent local infection and adhesions from causing anal stenosis. For stenosis that has already appeared should be treated by dilating the anus 1-2 times each time for more than 15 consecutive days for a more satisfactory treatment effect. If the symptoms of anal stenosis are still serious or even affect the function of exhaustion and defecation after surgery through conservative treatment and comprehensive treatment with drugs, it is better to go to a regular hospital for secondary surgery for anal stenosis, which can relieve the symptoms of stenosis caused by doing PPH for hemorrhoids.
