Cryptitis Surgery- Colorectal Medicine

  • Cryptitis is associated with repetitive sphincter trauma from spasm, recurrent diarrhea, or passage of large/hard stools.
  • Pathophysiology
    • Anal crypts are mucosal pockets that lie between the columns of Morgagnia
      • Formed by the puckering action of the sphincter muscles
    • Superficial trauma (diarrhea, trauma from hard stool) → breakdown in mucosal lining
      • Bacteria enter, inflammation extends into lymphoid tissue of the crypts / anal glands
      • Can lead to anal fissure, anal fistula, perirectal abscesses

Surgical referral is indicated when:

  • Infection has progressed and the crypt will not drain adequately on its own
  • Surgical treatment is excision
