Anorectal Malformation Surgery

Anorectal Malformation Surgery


Anorectal malformations prevent
children from having bowel movements due to the anus,
rectum, and other organs not developing properly during
pregnancy. Some children may only need one operation to
correct the malformation, but most need three, including the
PSARP, which was created by Dr. Pena, Director of the
International Center for Colorectal Care. The first
operation is a colostomy. The surgeon splits the colon into
two and brings each end through the abdominal wall forming two
openings. This allows the stool to temporarily pass into a bag
outside of the body. A few weeks later, surgeons use the PSARP,
or “Pena Procedure,” to place the anus in the correct
location. They start by removing the connection with the urinary
or genital tract, and pulling the rectum through the center of
the sphincter muscles to connect it to the anus. This forms a new
path for stool to leave the body and allows the child to use the
sphincter muscles in the anus. The final operation is completed
about two months later, once the child has healed. During this
operation, the colostomy bag is removed, and the surgeon
reconnects the two ends of the colon. After this final surgery,
the child is able to have a bowel movement. Treatment of an
anorectal malformation can be complex. That’s why it’s
important to see a multidisciplinary colorectal
team. For more information or to make an appointment, visit our
