As you gaze at your newborn baby, have you ever noticed that his or her body is a little yellow? Usually, most newborns experience a slight jaundice in the first week or two, which usually goes away after a few days. But have you ever wondered about the color of your baby's stool? Sometimes it looks pale or gray? If you see both of these things together, don't be fooled into thinking that it's normal. Because it could be a sign of a serious condition called Biliary Atresia, which we're talking about today.
Simply put, what is Biliary Atresia?
Think of the liver in our body as a small factory. This factory produces a liquid called "bile" as a waste product. This bile travels from the liver through a very fine system of tubes (bile ducts) and ends up in our small intestine. Bile has two main functions. One is to help remove unwanted waste products from the body. The other is to help digest the food we eat, especially fat, and absorb the nutrients our body needs.
Biliary Atresia is a condition in which the delicate tube that carries bile is blocked or not formed properly at birth. This means that the bile produced in the liver has no way to get out, and instead gets stuck inside the liver. This is like blocking all the garbage disposal routes in a city. All the garbage accumulates inside the city, and the entire city is destroyed. When the bile gets stuck inside the liver, it starts to seriously damage the liver.
This is a serious condition that affects young babies in their first few months. If not treated quickly, it can cause severe liver damage and even liver failure.
But don't worry. Medical science is very advanced now. If this condition is detected early, surgery can create a new path for bile to flow. That's why it's very important to be aware of these symptoms.
What are the main symptoms of Biliary Atresia?
These symptoms usually start to appear within a few weeks of the baby's birth. As parents, you should be very attentive to this.
| Symptom | Description |
|---|---|
| Yellowing of the skin and eyes (Jaundice) | This is the main and first symptom. The baby's skin and the whites of the eyes turn yellow. Although jaundice is normal for newborns, it is a warning sign if it lasts for more than two weeks. |
| Pale poop | This is also a very important symptom. Stools are normally yellow, brown, or green in color because of bile. Because bile is not reaching the intestines, the baby's stools are pale beige, gray, or clay-colored. Doctors call these "acholic stools." |
| Dark urine | As bile, which accumulates in the liver, enters the bloodstream and is filtered through the kidneys, the baby's urine takes on a dark yellow or orange color. |
Other symptoms that appear over time
By the time your baby is about 6 to 10 weeks old, these symptoms may also appear:
- Itchy skin: The accumulation of bile in the body can cause severe itching of the skin.
- Frequent crying and irritability: Due to physical discomfort, the baby may be irritable and cry frequently.
- Failure to thrive: Without bile, food is not digested properly, so the body does not absorb nutrients. As a result, the baby does not gain weight properly.
- Abdominal swelling: The liver is damaged and the abdomen begins to fill with fluid, causing the abdomen to protrude and become swollen.
Why does Biliary Atresia occur?
Many parents have questions like, "Why did this happen to our baby?" "Did we do something wrong?" Researchers still aren't 100% sure what causes this.
However, the main idea is that this condition is caused by a somatic genetic mutation that occurs during the formation of the bile ducts while the baby is developing in the mother's womb. The important thing is that this is not something that is inherited from the parents to the child. Also, this condition is not caused by anything you did or said during pregnancy. So don't worry about it or blame yourself.
What complications can occur if left untreated?
Biliary atresia is a condition that requires immediate treatment. Delaying treatment can lead to serious complications.
- Permanent liver damage (Cirrhosis): Continuous bile retention causes liver cells to die, causing the liver to become scarred and stone-like. This can lead to complete loss of liver function.
- Portal hypertension: When the liver is injured, the blood flow through it is obstructed, causing high blood pressure in the veins that carry blood to the liver.
- Ascites: Water begins to accumulate in the abdominal cavity due to liver failure and portal hypertension.
- Hepatomegaly: The liver becomes swollen and enlarged due to bile accumulation and injury.
- Esophageal Varices: Portal hypertension can cause the veins in the esophagus to swell and burst. This can cause severe internal bleeding that can be life-threatening.
All of these can lead to liver failure. However, if you recognize the symptoms early, see a doctor, and start treatment, many of these complications can be prevented.
How to diagnose the disease? (Diagnosis)
If your baby has jaundice for more than two weeks, or if you suspect that their stools are pale, see a pediatrician immediately. The doctor will first examine your baby.
- Checks for yellowing of the skin and eyes.
- They will check by hand to see if the stomach is swollen or the liver is enlarged.
After that, several tests are ordered to confirm the disease.
| Test | Simply explained |
|---|---|
| Blood Tests | These tests are done to check liver function, the amount of bilirubin in the blood (the cause of jaundice), and whether the liver has been damaged. |
| Abdominal ultrasound scan | This helps to see the condition of the liver, gallbladder, and bile ducts from the outside. |
| HIDA scan test | This is a special scan. Here, a special fluid (tracer) is injected into the body and a camera is used to monitor how it travels with the bile from the liver. If the bile is not flowing into the intestine, it can confirm that the bile duct is blocked. |
| Liver biopsy (examination of a small piece of the liver) | If necessary, a very small piece of tissue is taken from the liver using a very small needle and examined under a microscope. This can help determine if there are specific changes in the liver cells related to biliary atresia. |
| Intraoperative Cholangiogram | This is a test that is done during surgery. The surgeon injects a special dye into the gallbladder and looks at it with an X-ray. If the dye does not pass into the intestine, it is 100% certain that the bile duct is blocked. If so, treatment is done during the surgery. |
Treatment method: Kasai Procedure
The main and first line treatment for Biliary Atresia is the Kasai Procedure . This is not a disease that can be cured with medication.
Simply put, in this surgery, the surgeon removes the blocked bile duct, takes a small section of the baby's own small intestine, and connects it directly to the liver. This is like removing a broken road and creating a brand new 'bypass' in its place. Through this new route, bile produced in the liver begins to flow directly into the intestine.
The sooner this surgery is performed, the more successful the results. Especially if this surgery can be performed before the baby is 3 months old , and if possible within the first month, the chances of minimizing damage to the liver and achieving successful results are much higher.
After the surgery, the baby's jaundice gradually subsides, the color of the stools returns to normal, and the baby's weight begins to increase as digestion improves.
But, is Kasai surgery a permanent solution?
In most cases, Kasai surgery is not a lifelong solution. Because there may already be some damage to the liver before the surgery. That damage can gradually increase over time.
Many children who have undergone Kasai surgery will need a liver transplant in childhood or adolescence. But this is not something to be afraid of. Today, liver transplants are very successful. Through this, the child has the opportunity to live a completely healthy, long-term life.
How do you, as parents, take care of your baby?
When you find out that your baby has Biliary Atresia, it can feel like your whole world is turning upside down. It's a very difficult time. But you're not alone. The medical team will explain everything to you and help you.
- Special Nutrition: To ensure that the baby is getting the proper nutrition, the doctor will provide special formulas, vitamins, and additional nutritional supplements.
- Long-term medical monitoring: The baby must be taken to the clinic on scheduled dates. The doctor will regularly check the baby's growth and liver function.
- Signs to watch out for after surgery: When you bring your baby home after caesarean section surgery, keep an eye out for these signs.
- Fever
- If the body turns yellow again (jaundice)
- If the stools become pale again or the urine becomes dark
If you see something like this, call your doctor immediately.
- Think about yourself too: You will feel very tired both mentally and physically with all this. Ask for help from family and friends. Make time for yourself to rest and sleep. Also, talking to other parents who have a child will be a great source of strength for you.
Take-Home Message
- If a newborn baby's jaundice (yellowing) lasts for more than two weeks , don't consider it normal.
- If your baby's stool is pale, gray, or clay-colored , it is a serious symptom.
- If you notice one or both of the above symptoms, do not delay and see a pediatrician immediately.
- In the case of Biliary Atresia, early diagnosis and prompt referral for surgery (Kasai Procedure) are very important for the child's future.
- This condition is not caused by any fault of yours. It is not a disease that is inherited from parents to children.
