Is Having An Imperforate Anus A Birth Hereditary
An imperforate anus or anorectal malformations are birth defects in which the rectum is malformed. Anorectal malformations are a spectrum of different congenital anomalies in males and females, that varies from fairly minor lesions to complex anomalies. Even cause is unknown, a genetic basis is associated in ...Read more
Charity: I'm not sure if you are looking for one to donate to or if you are looking for help for someone you know with the condition. I am not aware of a specific organization that just deals with imperforate anus. However, if you contact the Pediatric Surgery department of your local Children's Hospital, they likely have charitable foundations set up that deal with kids with this defect.
Imperforate anus: An imperforate anus or anorectal malformations are birth defects in which the rectum is malformed. Anorectal malformations are a spectrum of different congenital anomalies in males and females, that varies from fairly minor lesions to complex anomalies. Even cause is unknown, a genetic basis is associated in about 10% of patients.
A colostomy remains: There are various degrees of imperforate anus. If a septum alone is present it can be perforated and bowel will function. Various forms of proctoplasty have been employed to leave a functional anus but if colostomy was required at birth, there is no way to repair the problem since pulling bowel thru area with no sphincter, leaves incontinence. People function with colostomies and irrigate stoma
Yes: During fetal development the internal structure of the large intestine grows toward the point where the anus should be & the external skin meets it. If the two both attach & make the opening a normal anus is formed. If the inside doesn't make it all the way down, or the opening doesn't form it is imperforate. There are variations in degree and the amount of work needed to fix it.See 1 more doctor answer
Depends: It depends on the level of the defect. If the defect is "low" or close to the perineal skin, an anoplasty can be done shortly after birth. If the defect is high, then a staged operation is needed. Initially the child will need a colostomy (temporary). Second stage is creation of anus. Third stage is closure of colostomy after the anoplasty heals.See 1 more doctor answer
Define perminent!: The complexity of the surgery for anal defects varies with the defect. If it is a short pull thru and the sphincter muscles can be preserved a favorable outcome with a single procedure may be possible. A complex repair with take down of a fistula and complications may need modifiations over time. Some kids may never have control as they grow older. Each case has unique issues.See 2 more doctor answers
Almost always: As far as creating an outlet for passage of stool, operations for imperforate anus are almost always successful. However, depending upon the status of sphincter muscle present (poor with high and good with lower anomalies), the functional results may not be perfect. Children with lower anomalies tend towards constipation, while those with higher anomailes & poor muscle tend towards incontinence.See 4 more doctor answers
No: Imperforate anus is a congenital defect that occurs prior to birth and occurs sporadically without forwarning. Usually diagnosed at birth, treatment includes colostomy, anal reconstruction, and colostomy closure in a staged fashion. Hence prevention is nigh impossible at this time.See 2 more doctor answers
You can and you will: Anal atresia (imperforate anus) is rare and associated with several syndromes. Once detected conclusively during the first neonatal examination, it is a surgical urgency and repair has to be done within hours of life (either definitive or preliminary, depending on the nature of the defect).See 1 more doctor answer
Surgery: The fix on this varies with the degree of the defect. I have treated patients with a minor barrier or membrane, where the fix was just opening the anus and pulling through the rectal tissue. Others had a high defect, requiring a colostomy until they were older when a repair could be done. Data shows some, male or female where odd fistulas occur, requiring repair. All require specialized surgery.
Terminology issues: The lower colon forms from tissue that develops an inner tube. It grows on the inside down to where the anal opening should be. As the internal tissue meets the outside skin from the inside, the skin barrier between the structures dissolves and the anus "perforates". If the internal structure does not come close to the skin, or the outer skin stays separate, the hole cannot form. (imperforate)
Lack of anal opening: An imperforate anus is a congenital anomaly in which a baby is born without an anal opening altogether, one that is too small, or one that is located in the wrong place (for example, opening into the vagina in a girl or into the bladder in a boy). It is definitively repaired with surgery to create a good anal opening in the right place. Sometimes, a colostomy is done first.See 1 more doctor answer
Poor signals: The imperforate anus can occur in isolation or as part of a syndrome. During fetal development the gut starts as a sausage like mass that forms a central cavity, lengthens & moves down from the inside to join up with the external skin at the anus. The defect can be as minimal as a thin membrane in normal position or gut ending far from the anus. Poor signal decoding triggers this defect.See 2 more doctor answers
Asking why: Don't seek any particular explanation for this fairly common birth defect. You won't find this inquiry productive. Any theorizing is idle speculation. Searches for the real cause (s) have been unrewarding.See 1 more doctor answer
Not likely: No known genetic causes, although there are families with more than one child affected.
