Have you ever heard of Zollinger-Ellison Syndrome ? It may sound like a strange name, but it's a condition that can affect our intestines and is something to be concerned about. It causes severe stomach ulcers and chronic diarrhea due to the overproduction of acid in our stomach. So, let's talk about it in a little more detail today, shall we?
What exactly is Zollinger-Ellison Syndrome?
Simply put, the main cause of this condition called Zollinger-Ellison Syndrome (ZES) is a type of small tumor that develops in our body, especially in the pancreas or the upper part of the small intestine (duodenum). We call these tumors gastrinomas . These are actually a type of neuroendocrine tumors .
Now look, these gastrinomas produce a hormone called gastrin . This gastrin hormone is what signals our stomach to "Okay, start making acid now." So, when these tumors produce too much gastrin hormone, the stomach also produces too much acid. Just think of it like a faucet leaking water without closing it tightly, our stomach acid increases uncontrollably. This excess acid is what causes problems like stomach ulcers and acid reflux.
It's a bit worrying that about 60% of these gastrinomas can be cancerous . But don't worry, like everything else, there is a treatment for this too. Sometimes doctors also call this condition "pancreatic ulcerogenic tumor syndrome."
What are the symptoms of this? How do we feel?
Sometimes, Zollinger-Ellison syndrome (ZES) may not cause any symptoms. However, when symptoms do occur, they may include:
- Stomach burning or pain: You may feel a burning sensation inside your stomach, or like something is eating you. This is caused by the excess acid.
- Blood in vomit or blood in stool: This is caused by bleeding from wounds inside the intestines (gastrointestinal bleeding).
- Fatigue and weakness: As mentioned above, due to blood loss, you may feel tired and weak due to anemia.
- Oily, floaty stools: Some people may notice a change in their stools, which may be more oily.
- Heartburn: To be precise, it is a burning sensation in the chest caused by acid coming up the esophagus.
- Bloating, indigestion: This may be felt more, especially after eating a fatty meal.
- The food is tasteless.
- Nausea and vomiting.
- Being thin for no reason.
The severity of these symptoms depends on the size and number of gastrinomas. Larger tumors produce more gastrin, which causes the stomach to produce more acid. This can make the symptoms of peptic ulcer disease worse.
Remember, sometimes these tumors can metastasize to the liver, leading to liver cancer. If that happens, symptoms such as itching, yellowing of the whites of the eyes, and yellowing of the skin (jaundice) may also occur.
Why do we have this situation? What are the reasons?
Most of the time, Zollinger-Ellison Syndrome (ZES) occurs sporadically , meaning it's difficult to pinpoint the exact cause.
However, about 25% of people with this condition have been found to have a genetic condition called MEN Type 1 (Multiple Endocrine Neoplasia Type 1) . MEN Type 1 is a rare, inherited condition in which tumors can develop in multiple endocrine glands in our body.
What complications can arise from this condition? Should I be worried?
Yes, Zollinger-Ellison Syndrome (ZES) is a condition that can sometimes be life-threatening . For example, if a gastrinoma blocks the upper part of the small intestine (duodenum), it can burst. It can also spread to the liver. Severe gastrointestinal bleeding can occur due to excess stomach acid.
However, don't panic when you hear these things. If the disease is diagnosed early and treated properly, these complications can be largely prevented.
How do doctors diagnose this disease? (Diagnosis)
If you have these symptoms, a doctor will first examine you, ask about your symptoms and whether anyone in your family has had these conditions. Then, they may do tests such as:
- Blood tests: These can check if your blood gastrin hormone levels are too high (hypergastrinemia).
- Imaging tests: A CT scan or MRI scan may be done to see if there are gastrinoma tumors in the pancreas or duodenum.
- Stomach acid test: In this test, a doctor inserts a small tube into the stomach through the nose or mouth and takes a sample of the acid there.
If these initial tests identify tumors, the doctor may perform several more tests:
- Endoscopy: In this test, a small tube with a camera attached is inserted through the mouth and the esophagus, stomach, upper part of the small intestine (duodenum), and pancreas are examined.
- Endoscopic ultrasound: This is a combination of ultrasound and endoscopy. It can produce clearer images.
- ERCP (Endoscopic Retrograde Cholangiopancreatography): This is also a special scan. It looks inside the bile ducts and pancreatic ducts.
- Fine-needle aspiration: If there is a tumor, this method is used to take a small piece of it and test it for cancer cells (biopsy).
What are the treatments for this? (Treatment)
Treatment options depend on how severe your symptoms are and whether the gastrinoma is cancerous. There are three main types of treatment:
1. Medication:
- The main medication that is often prescribed is proton pump inhibitors (PPIs) . These medications work by reducing the amount of acid produced in the stomach. Simply put, they control the excess acid produced.
2. Surgery:
- Your doctor may recommend surgery to remove the tumor. There are several types of surgery:
- Duodenectomy: The tumor is removed through a small incision in the upper part of the small intestine (duodenum).
- Gastrectomy: Removal of part or all of the stomach.
- Liver surgery: If there are tumors in the liver, they are removed.
- Pancreatectomy: Removal of part or all of the pancreas.
- Tumor enucleation: If there are tumors in the head of the pancreas, only those are carefully removed.
3. Cancer therapy:
- If the tumor is cancerous, your doctor may recommend treatments such as chemotherapy . These treatments can help reduce symptoms and slow the spread of the tumor.
Can treatment completely cure it?
If a cancerous gastrinoma can be completely removed with surgery, the condition may be completely cured . However, this requires removing all of the cancer cells in the body. Even if the surgery is successful, you will often have to take medication to control stomach acid for the rest of your life.
If I have this condition, what should I expect? (Prognosis)
The prognosis for you with this condition depends on the type of tumor. Noncancerous gastrinomas are not life-threatening. However, you will need ongoing treatment to control stomach acid levels.
However, the situation changes if you have cancerous tumors. In that case, you may need surgery and follow-up cancer treatment.
Survival rates for people with Zollinger-Ellison syndrome (ZES) vary. According to the data, after all gastrinomas are surgically removed, more than 90% of people live for 5 to 10 years . However, if all tumors cannot be removed, the 5-year survival rate drops to 43%. It is important to remember that these are just statistics. If you have this condition, talk to your doctor about what you can expect.
How should I take care of myself? What can I do?
It depends on your condition. Many people have to take medication to reduce stomach acid for the rest of their lives. Zollinger-Ellison syndrome (ZES) is caused by gastrinomas. Most of these tumors can be cancerous. So, if you have had cancerous tumors, you need to continue to see your doctor for follow-up care to see if they have come back.
When should I see a doctor again?
After treatment, if your Zollinger-Ellison Syndrome (ZES) symptoms worsen or new symptoms appear, you should see a doctor immediately.
When you find out that you have such a rare disease, you may be surprised and a little scared. It can be hard to hear something like this all of a sudden, even though you may not have any symptoms. You may have many questions about how ZES will affect you. The answers to those questions can vary greatly depending on your situation.
The most important thing is to discuss all your questions and doubts with the doctor. They will explain everything to you and give you the support you need.
Take-Home Message:
