Q What is Ano-rectal
An anal abscess is an infected cavity filled with pus
found near the anus (the opening of the anal canal) or
rectum (the portion of large intestine just proximal to
the anal canal). This can results from a blockage of the
anal glands located just inside the anus. According to the
crypto-glandular theory, abscesses often develop from
cryptitis which may be associated with an enlarged
papillae in the anal canal. They start as cellulitis-a
diffuse inflammation, characterized by swelling and
redness, which has not yet localized to form an abscess.
Then the infecting organisms burrow into the anal glands,
producing circumscribed areas of pus in the region of the
anus and rectum.
abscess produces pain and swelling near the anal opening. Fever may also be
present. Treatment consists of surgically draining pus from the infected cavity
and making an opening (incision) in the skin near the anus to relieve pressure.
Sometimes a small catheter is left in the incision for several days to assure
adequate drainage. In 8-50% of individuals, a fistula will form after the
abscess has been drained.
