What is this sclerosing mesenteritis?
Simply put, sclerosing mesenteritis is a rare disease that affects a part of your mesentery. Now you're probably wondering what the mesentery is. It's the tissue that helps hold your intestines to the back wall of your abdomen. It's like a curtain, to be precise. "Mesenteritis" refers to inflammation, which means swelling, in this mesentery. "Sclerosing" refers to scarring and hardening. So, in sclerosing mesenteritis, there's a long-term inflammation of this mesentery. Over time, this inflammation causes scarring (fibrosis) in the tissue, which gradually hardens. Your mesentery is part of the visceral peritoneum, which surrounds the organs in your abdomen and helps hold them in place. It is made up of two layers of membrane (peritoneum) folded in two, with a layer of fatty tissue (adipose tissue) in between. In sclerosing mesenteritis, this inflammation affects the fatty tissue layer in the middle. That is why that part becomes thick and hard. Sometimes this can happen in one place or in several places. When viewed on radiological tests, these can look like tumors.Is this a chronic condition?
Yes, it is actually a chronic condition. Because for the tissue to become scarred enough to harden (sclerosis), there has to be inflammation for a long time. This doesn't happen all at once, it happens in stages. First, the fatty layer breaks down little by little. Then, different types of cells come and join the tissue. Finally, scar tissue forms. So, in that sense, sclerosing mesenteritis is a chronic, progressive disease. But that said, it doesn't always get worse. In most cases, it can even go away on its own.Are Sclerosing Mesenteritis and Mesenteric Panniculitis the same thing?
Many doctors consider both conditions to be the same. They describe both as "idiopathic" inflammation of the mesentery. That is, the inflammation appears to occur suddenly, without any specific cause. However, some argue that the name "sclerosing mesenteritis" should be used to describe a more severe form of the disease, or a more complex form in which symptoms have been present for a longer period of time. "Mesenteric panniculitis" means "inflammation of the fatty tissue of the mesentery." Since this name does not refer to scarring (sclerosis), some argue that the name "mesenteric panniculitis" should be used to describe the early stage of inflammation, that is, the stage before scarring occurs. They say that when scars start to form, it means the disease is quite advanced and may be a little difficult to treat.Who is affected the most by this situation?
Sclerosing mesenteritis is a very rare condition. It affects about 0.6% of the population. With only about 200 cases reported so far, we are still learning about it. It most often affects people over the age of 50. Many people who develop the disease have a family history of autoimmune diseases. Also, research shows that about 60% of patients have had or currently have cancer, especially lymphoma.Is Sclerosing Mesenteritis a cancer?
No, this is not cancer on its own. But it is often associated with cancer. One cause of chronic inflammation is cancer. And infections are another. Research shows that people who have inflammation due to this cause are more likely to develop sclerosing mesenteritis. It's as if their mesentery "takes over" the inflammation and continues to do so. The scar tissue grows like cancer, but it doesn't spread. But sometimes it can look like it's "spreading." It can also look like cancer on x-rays. In sclerosing mesenteritis, a solid, hard mass of scar tissue is often seen in one place in the mesentery, like a tumor. The symptoms of both conditions can sometimes be similar. So doctors need to take some time and do a few tests to differentiate between the two.What could be the symptoms?
Think about it, many people can have this condition without any symptoms , and they don't even know they have it. The most common symptoms are stomach pain and bloating.If the inflammation is severe, you may have diarrhea or a fever. You may also feel a palpable mass in your abdomen. Very rarely, this mass can cause a blockage in your small intestine. This can cause additional symptoms such as nausea, vomiting, and weight loss.What is the reason for this?
The exact cause is not yet known. But doctors suspect that it may be a type of autoimmune disease . That is, the inflammation is caused by an inappropriate or overactive response by our body's immune system. Your immune system normally uses inflammation to fight off germs that enter the body and to heal damaged tissue. When your immune system goes into overdrive in the absence of any obvious threat, it's called an autoimmune response. There are different types of autoimmune diseases that cause chronic inflammation in different parts of the body. We don't know exactly why they develop, but it seems to have a genetic component, and they can also be triggered by physical stress, such as an illness or injury. People who develop sclerosing mesenteritis often have a family history of autoimmune diseases, and sometimes they may also have other autoimmune diseases.How to accurately diagnose this disease?
A doctor follows several steps to diagnose this disease.Imaging Tests
Your doctor will take x-ray images of the mesentery to look for signs characteristic of sclerosing mesenteritis.- First, you can have an abdominal ultrasound . It's a quick and easy test.
- If there is any doubt about this condition, they will refer you to a more sensitive test. This could be a CT scan (computed tomography scan ) or MRI (magnetic resonance imaging). These tests look for a focal mass and signs of tissue breakdown and scarring (fibrosis) around it.
- If these tests cannot clearly distinguish between sclerosing mesenteritis and cancer, a PET scan (positron emission tomography) may help confirm the diagnosis. This involves injecting a safe, radioactive substance radioactive tracer into the body. A CT scan or MRI uses this radiationImages are produced as they are detected. Cancer cells absorb this radioactive material more than other cells.
Biopsy
If all else fails, your doctor may need to take a sample of tissue from the mesentery for a biopsy. A pathologist will analyze the tissue sample and make a final diagnosis. This tissue sample is usually taken through a needle inserted into the abdomen. Some people may also need to have a less invasive procedure called a laparoscopy to examine the mesentery and take a sample. This involves inserting a camera through a small incision.What are the treatments for Sclerosing Mesenteritis?
The good news is that most people never need treatment. Sclerosing mesenteritis is often a self-limiting, self-limiting condition that gets better on its own. You may never have any symptoms, or you may only have mild discomfort that can be controlled with over-the-counter (OTC) medications. However, if you have persistent symptoms, your doctor will prescribe a variety of medications to treat them. These may include:- Corticosteroids, such as prednisone, are used to control inflammation .
- Immunosuppressants, such as azathioprine, reduce the autoimmune response.
- Hormonal therapy , for example tamoxifen.
The most important thing is to get these treatments under medical advice. It can take some time to find the right treatment for you, so it's important to stay in touch with your doctor.
