What is the most common type of anorectal malformation?
What is the most common type of anorectal malformation?
The majority of male patients with an anorectal malformation have some form of connection to the urinary system, or a recto-urethral fistula (approximately 70% of this patient population). The most common type of anorectal malformation in female patients is a recto-vestibular fistula.
How is anorectal malformation treated?
Doctors treat anorectal malformations with surgery. The type of surgery depends on the location and type of malformation. Doctors often perform surgery in the first few days after the baby is born. In some cases, doctors can repair the anorectal malformation with one operation.
What are the causes of anorectal malformation?
What causes anorectal malformations?
- VACTERL association (a syndrome in which there are vertebral, anal, cardiac, tracheal, esophageal, renal and limb abnormalities)
- digestive system abnormalities.
- urinary tract abnormalities.
- abnormalities of the spine.
Is anorectal malformation hereditary?
Imperforate anus is a birth defect that usually appears to occur randomly for unknown reasons (sporadically). Less commonly, the condition may be familial, suggesting autosomal dominant, autosomal recessive, or X-linked recessive inheritance.
What is the associated malformation for anorectal anomaly?
The most severe forms of malformation-associated morbidity are fecal and urinary incontinence. Higher malformations, such as long–common-channel cloacae and prostatic or bladder-neck fistulas, are associated with poorer nerve and muscle formation, all of which increase the likelihood of fecal or urinary incontinence.
What is the meaning of anorectal malformation?
Anorectal malformations are birth defects in which the anus and rectum (the lower end of the digestive tract) don’t develop properly. They occur in an estimated 1 in 4,000 newborns and can range from mild to complex.

What type of colostomy is used for anorectal malformation?
The pediatric colostomy is used as an imperforate anus repair to divert the fecal stream and thereby allow passage of stool into a stoma bag. It also is important to protect the surrounding area for future reconstructive surgery.
Can your sphincter muscle stop working?
The anal sphincter may become weak either from direct damage to the muscle or from damage to the nerves that cause the muscle to contract normally. Damage to muscles can be caused by: Childbirth. Rectal surgery.
What are anorectal malformations (ARMs)?
Anorectal malformations (ARMs) are a complex group of congenital anomalies involving the distal anus and rectum, as well as the urinary and genital tracts in a significant percentage of cases.
What is cloaca in anorectal malformations?
Many children with anorectal malformations have a fistula, or abnormal passage, between the rectum to another part of the body, such as the In some children with anorectal malformations, the rectum and the urinary tract have the same opening. This abnormality is called a cloaca. How common are anorectal malformations?
What is the International Conference on anorectal malformations?
Therefore, an International Conference for the Development of Standards for the Treatment of Anorectal Malformations was organized at Krickenbeck Castle near Cologne, Germany (17-20 May 2005). This workshop brought together 26 international authorities on congenital malforma tions of the organs of the pelvis and perineum.
What is the history of ano-rectal malformations?
In 1971 Douglas Stephens and Durham Smith published the first update of their book, called ” Ano-Rectal Malformations in Children”. It became the standard work for ARM for the following 17 years.
