Techniques for Congenital Anal Deformity Encountered in Later Life
Most cases of congenital abnormality of the ano-rectum are seen at, and treated soon after, birth [1,4,6,8]. Many of these abnormalities cause immediate problems of obstruction and have to be operated on as emergencies. It is rare nowadays for cases of imperforate anus or Hirschsprung’s disease not to undergo definitive operations during the first year(s) of life to correct the underlying abnormalities. However a few children are able to survive in spite of a congenital abnormality when the obstructive element is weak. There are two different routes by which such rare children progress untreated up to adult life. The first is following faulty partial surgical correction of a low type of imperforate anus. In these babies, the correct diagnosis is made, but the surgical incision to open the obstructed orifice (usually a “covered-anus” deformity) is placed in the wrong position, so creating in effect a fistulous opening that lies outside the anal ring (usually anteriror to the anal muscles).
