Investigations and Surgeries

As a parent you should be encouraged and supported to actively participate in your baby's care. This usually includes being able to spend time with your baby, hold your baby and be involved in care team discussions and the decision-making processes. It is much better to ask questions if something isn’t clear and especially if you are worried about something in particular.

Babies with an Anorectal Malformation (ARM) are ideally diagnosed within the first few hours after birth.

However, diagnosis may sometimes be delayed if the baby is passing meconium, the first stool, through a fistula connected to the bladder or vagina, or if a thin “ribbon like” stool is passed through a narrow anus.

Treatment options

The short term aims are to make your baby safe and to reconstruct the lower bowel to allow stool to pass through the anus.

Treatment for Anorectal Malformation (ARM) is different for each child, depending on the type of the condition.

Some infants with less complex malformations may need only one operation, while others, for example those with more complicated conditions, might need up to three staged procedures.

Before any surgical treatment is carried out, x-ray studies and other investigations are essential.

These assessments provide detailed information about the malformation, helping to determine the most appropriate surgical approach.

Single Stage Procedure

A single stage procedure is performed when it is known that the bowel does not open into the urinary tract and the baby is well enough to have the operation in the newborn period.

For babies to be suitable for this approach it is most common that the opening (the anus) is visible on the skin but is incorrectly positioned or narrower than normal (anal stenosis).

In most cases, this procedure can be done without the need for a colostomy (an operation to make an opening on the tummy that the faeces/poo comes out of into a bag).

There are different surgical techniques in this situation, for example an anorectoplasty (an operation to correct the malformation).

More complex types of ARM

If it isn’t clear that the end of the bowel lies on the skin then operating without knowing where the opening is can be dangerous.

That is because the bowel often opens in the urinary tract or close to it, and this part of the body is more likely to be damaged when trying to find the bowel.

Having a stoma means that the faeces (poo) can by-pass the blockage for a few months until the surgery to make a new opening has been done.

It also means that further x-ray tests can be done.

These babies will need an operation to create a temporary stoma, also known as a colostomy.

A stoma is made by bringing part of the large intestine out onto the tummy.

This allows the intestine to function normally while keeping the lower bowel free from stool in preparation for corrective surgery.

When a baby has a colostomy part of the treatment should be to make sure that parents are ready for any challenges they may face looking after their baby and the stoma once they are at home.

Parents should work with their clinical teams before discharge to gain both knowledge and practical skills to confidently care for their baby.

To support this transition, a specialist colorectal and/or stoma nurse should be introduced to the family early on. Their role is to educate parents on caring for their baby’s stoma, including how to notice and manage potential issues.

This guidance includes checking the skin around the stoma, checking the size and colour of the stoma and addressing any concerns that may arise.

Before the baby is discharged home, a follow-up appointment with the surgeon and other multidisciplinary team members is arranged to ensure ongoing care and support.

Assessments and Investigations

Before the surgical repair can take place, further assessments and investigations may be needed to gather detailed information about your child’s condition.

The information helps the surgical team to:

Accurately diagnose the specific type of ARM.
Identify the exact position of the rectum.
Check the relationship of the rectum with other parts of the body.
Make sure the bowel is long enough to do the reconstruction.
Plan the surgical repair.
Predict the child’s future bowel control and treatment needs.

This is a condition where urine flows backward from the bladder into one or both ureters, and sometimes to the kidneys.

This can cause urinary infections and potentially harm the kidneys over time. In some cases of anorectal malformations (ARM) different treatments are needed to ensure the bladder works properly and the kidneys stay healthy.

This investigation helps doctors get a detailed view of the bladder and urethra during the passing of urine.

This test is important to see if there are any problems with how the urine flows through the bladder and urethra and is often done as part of the distal loopogram.

Additional assessments such as urodynamics and cystoscopy may also be performed to see if there are any other problems.

The VCUG provides a clear view of the bladder and urethra, helping to detect:

Urinary reflux (urine flowing backward into the ureters or kidneys)

Structural abnormalities of the bladder or urethra

Other urinary issues that may need treatment

The PSARP operation is typically performed within the first year of life, once the baby has gained sufficient weight.

The procedure is a delicate and crucial step in the surgical treatment of Anorectal Malformation.

The goal of the PSARP procedure is to reconstruct an anus and rectum to provide the best possible conditions for continence.

During this operation, the rectum is found, carefully freed from the urinary tract and pulled down towards the skin. The muscles that help with continence (sphincters) are identified both at the skin level and higher up in the pelvis. The muscles themselves may be abnormal in children with Anorectal Malformation so they might be quite thin.

The bowel is then sewn into a newly created anal opening in the perineum (the area between the genitals and anus) within the muscles to give it as good a chance as possible to work well.

Following the procedure, the child will continue to use the stoma to allow the bowel and newly formed anus to heal properly.

Sometimes dilatations of the newly made anus are recommended, and if so this should be started following discussion with you and training has been provided.

A distal loopogram (or colostogram) is a special type of X-ray done after the stoma surgery to provide a clear picture of the child’s condition.

This procedure is an important step in ensuring the best outcome for your child.

Whilst the procedure is usually low risk, it does need radiologists with skill and experience to make sure the right information is collected, and the test is done as safely as possible.

Third Stage – Closure of Stoma

The closure of the stoma occurs when the child’s bowel is functioning well. During this operation, the surgeon disconnects the bowel from the stoma and seals the intestine, forming a fully functioning bowel.

Once the colostomy is closed, the child won’t immediately begin eating normally. Typically, within a few days after surgery, the child will begin passing air, followed by faeces (poo) that are initially greenish, liquid, and mucous in small amounts.

Following this the child will be able to pass faeces (poo) through the reconstructed anus.

Nutrition and Post-Closure Care

After the colostomy is closed, nutrition should be carefully managed to avoid stools that are either too hard (which can cause discomfort in the newly reconstructed anus) or too liquid.

Loose faeces (poo) is more common and may result in skin irritation, such as dermatitis or redness.It is important to use protective barrier ointments / cream on the buttocks as the skin is not used to stool and can become easily irritated and sore.

Fortunately, these issues are temporary. Within a few days or weeks, the number of daily bowel movements will decrease, faeces (poo) will become more solid, skin irritation will resolve as the body adjusts.

What happens next?

The medium and long-term goals focus on supporting both the child and their family through critical stages of life, including toilet training, childhood, adolescence, and adulthood.

The ultimate aim is to help the child achieve social continence (the ability to control bowel movements in social settings) and lead a fulfilling, unrestricted life.

However, there can be challenges on the way. This journey involves a multidisciplinary team of healthcare professionals, who work together to provide comprehensive care.

These specialists may include paediatric surgeons, nurse specialists, urologists, neurosurgeons, gynaecologists, general physicians, and GPs.

By following a holistic approach to care (looking at the whole person) and working closely with you, the team of professionals can greatly improve your child’s quality of life. This team effort helps empower children born with Anorectal Malformation to live with confidence and without limitations.
