Anal fissure (fissure-in-ano) is a very common anorectal condition. The exact
etiology of this condition is debated; however, there is a clear association with
elevated internal anal sphincter pressures. Though hard bowel movements are
implicated in fissure etiology, they are not universally present in patients with
anal fissures. Half of all patients with fissures heal with nonoperative
management such as high fiber diet, sitz baths, and pharmacological agents. When
nonoperative management fails, surgical treatment with lateral internal
sphincterotomy has a high success rate. In this chapter, we will review the
symptoms, pathophysiology, and management of anal fissures.
