We are a little hesitant to talk about some parts of our body, aren't we? The anus is one such place. However, it is very important for us to be aware of the health problems associated with this part. Sometimes, surgery may be required to resolve these problems. Today we are talking about one such surgery, Anoplasty. Even if you have not heard of this, knowing this information may be important for you or someone close to you someday.
What is Anoplasty?
Simply put, an anoplasty is a surgical procedure that repairs or reshapes your anus. As you know, the anus is the last part of our large intestine. It is a tube-like part about 3-4 centimeters long, surrounded by muscles. These muscles (sphincters) help in passing stool.
So, if there is a defect in the way the rectum works, this surgery is done to correct it. Some of these defects can be congenital, while others can develop later due to an accident or medical condition.
Anorectal surgery is a type of surgery that involves the anus and the last part of the large intestine (rectum).
Why is this surgery necessary?
There are two main reasons for having an anoplasty. Let's understand them clearly.
| Main reason | Simply put... |
|---|---|
| Anal Stenosis | This is most common in adults. Scar tissue forms inside the rectum, narrowing the passage. Think of it like a water pipe getting clogged with dirt. This is also called a "stricture." This makes it difficult to pass stool. Surgery is only necessary when other treatments fail to improve the condition. |
| Anorectal Malformations | These are defects that a baby is born with. For example, Imperforate Anus is a condition where the opening (hole) of the anus is not present or is blocked. Perineal Fistula is a condition where the opening of the anus is not where it should be, but rather opens somewhere else (often underneath). This opening is usually narrow, and it also lacks the ability to control stool. |
When is this surgery performed on a small baby?
It's normal for parents to be very shocked when they learn that a newborn baby has a problem like this. However, thanks to advances in medical science, there are effective solutions to this.
Some simple birth defects can be repaired with a simple anoplasty surgery, just a few days after the baby is born.
However, babies with more complex defects may need to undergo multiple surgeries.
In such cases, the doctor will first perform a colostomy . This means that a small opening (stoma) is created in the baby's abdomen, creating a temporary passageway for stool to exit. This allows the baby to defecate safely. Then, at the appropriate time determined by the doctor, an anoplasty is performed to properly repair the anus. After that, when the wounds have healed well, the temporary colostomy is removed, and the baby is able to defecate normally through the anus.
How should I prepare before surgery?
If you are an adult, your doctor will advise you to completely clean out your intestines (bowel prep) before surgery. This involves giving you a special liquid medicine (laxative) to drink. When you drink this, everything in your intestines will be expelled with your stool.
You will also need to control your diet for a day or two before taking this medicine. You will usually be told to eat a low-fiber diet and drink only clear liquids on the last day. It is very important to follow your doctor's instructions exactly.
What happens during the surgery?
The main goal of an anoplasty is to recreate a functioning anus. What your surgeon does may vary depending on your condition.
The surgery is usually performed under general anesthesia .
- For someone with anal stenosis: The surgeon removes the scar tissue that caused the narrowing. The anus then widens again. But then a small gap forms inside. To close the gap, a small piece of skin (skin flap) is taken from the outside of the anus, from the buttocks, and grafted to that place and sutured.
- For a baby with an anorectal malformation: The surgeon will need to create a new anus. This new anus will start in the colon, pass through the sphincter muscles, and open out in the correct place. If there are any fistulas that are opening in the wrong places, they will be closed. If the baby has a temporary colostomy, it will remain there until the new anus heals.
What are the possible complications after surgery?
As with any surgery, there are risks and complications that can occur, and it's important to be aware of them.
| Type of complication | Description |
|---|---|
| Short-term complications | |
| Infection | Infection can occur while the wound is healing. Your medical team will teach you how to prevent this. |
| Blood clot (Hematoma) | Blood can collect inside the wound and form a clot. This can be treated by applying ice and compression. |
| Difficulty urinating (Urinary Retention) | Some people may have difficulty urinating after surgery, which may require medication or a temporary catheter. |
| Constipation | Constipation may occur after surgery. The doctor will give you the necessary medication for this. |
| Long-term complications | |
| Fecal incontinence | This can happen if the surgery damages the muscles or nerves. Some children with birth defects may lose the necessary nerves and muscles from the start. Some people can manage this over time. Your doctor will talk to you about this. |
| Stenosis | If the anus is not dilated daily during the healing process, there is a high chance that it will narrow again. Therefore, it is imperative to perform dilation as directed by the doctor. |
| Diaper Rash | When babies first start defecating through the anus, they can develop a severe skin rash in that area. This is because the skin is not used to stool. Special ointments can help prevent and treat this. |
How is the recovery time?
The healing process usually takes about 4 to 8 weeks. During this time, you will need to do daily anal dilations . This is a very important step in the healing process. A special device (dilator) is inserted into the anus daily and pulled. This is done to prevent the anus from narrowing again and causing scarring as it heals.
It is normal to bleed a little when doing this, so don't worry. The doctor will give you medication to control the pain. He will also tell you to follow a special diet while you are healing.
Remember, these situations are not very common. However, if they do occur, anoplasty is a very effective treatment. Especially since a child with a severe birth defect may not be able to return to normal completely, this surgery can give them the opportunity to live as normal a life as possible.
Take-Home Message
- Anoplasty is a surgery performed to correct anal stenosis in adults or birth defects in babies.
- Some babies may need a temporary colostomy to pass stool before the main surgery.
- Daily anal dilation after surgery is essential to prevent the newly created passage from narrowing.
- Follow your doctor's instructions regarding wound care, diet, and follow-up visits.
- If you experience any problems, such as severe pain, signs of infection (swelling, redness, pus), or severe difficulty urinating/defecating, tell your doctor immediately.
