A Case Of Anal Fissure - Similima

� This tag is known as a sentinel pile- sentinel –
because it guards the fissure. There may be
spasm of the involuntary musculature of the
internal sphincter.
� Infection is common and may be severe ending
in abscess formation. A cutaneous fistula may
follow.
� Chronic fissure in ano may have a specific
cause- often a granulomatous infection- eg-
chron’s disease. Specific fissures of this type are
often less painful.
