![]() ![]() Longer internal anal sphincter division (to the dentate line, as opposed to the fissure apex only) may be more effective at reducing anal fissure. Open partial lateral internal anal sphincterotomy may be equivalent to closed partial internal anal sphincterotomy in fissure healing. We do not know whether internal anal sphincterotomy is better or worse than anal advancement flap in improving fissure healing. We do not know whether anal dilation is more effective than topical nitroglycerin at reducing the proportion of persons with anal fissure. One small randomized controlled trial found limited evidence that controlled anal dilation may be equivalent to sphincterotomy in fissure healing, with negligible incontinence risk. Symptoms of an anal fissure often include a tag of skin at the edge of the anus (sentinel pile), thickened. Internal anal sphincterotomy also increases fissure healing compared with digital anal stretch, and anal stretch is more likely to cause flatus incontinence. The acute anal fissure looks like a linear tear. It improves fissure healing compared with treatment with nitric oxide donors (topical nitroglycerin, topical isosorbide dinitrate), botulinum A toxin–hemagglutinin complex, and calcium channel blockers (nifedipine, diltiazem). Internal anal sphincterotomy is more effective than medical therapy for chronic anal fissure in adults. ![]() The cause is not fully understood, but low intake of dietary fiber may be a risk factor.Ĭhronic fissures typically have a cyclical history of intermittent healing and recurrence, but about 35% will eventually heal, at least temporarily, without intervention.Ītypical features, such as multiple, large, or irregular fissures, or those not in the midline, may indicate underlying malignancy, sexually transmitted infections, inflammatory bowel disease, or trauma. Anal fissures are a common cause of anal pain during and for one to two hours after defecation. The following natural remedies can help relieve sentinel piles discomfort. ![]()
