Mesenteric lymphadenitis vs appendicitis

Mesenteric lymphadenitis and appendicitis are two conditions that cause inflammation and pain in the abdomen, especially in the lower right side.

Both conditions can cause pain in the lower right side of the abdomen, but some differences exist. 

Inflammation of mesenteric lymph nodes, the tissue that links the intestines to the walls of the abdomen, is known as mesenteric lymphadenitis. An inflammation of the appendix, a tiny pouch connected to the colon’s cecum, is known as appendicitis.

Both conditions can have similar symptoms, such as abdominal pain, fever, nausea, vomiting and diarrhoea. However, some differences can help distinguish them.

Mesenteric lymphadenitis usually occurs after a viral or bacterial infection in the abdomen, such as gastroenteritis or strep throat. Appendicitis usually comes on suddenly, without any prior illness.

Mesenteric lymphadenitis can affect people of any age, but it is more common in children and teenagers. Appendicitis can also affect anyone, but it is more prevalent in young adults.

Mesenteric lymphadenitis is usually less severe than appendicitis and often resolves independently with rest and fluids. Appendicitis can be life-threatening if left untreated and usually requires surgery to remove the appendix.

To diagnose mesenteric lymphadenitis or appendicitis, a doctor may perform a physical examination, urine tests, blood tests, imaging tests (such as CT scan), or laparoscopy.

The treatment for mesenteric lymphadenitis depends on the cause and severity of the condition. It may include antibiotics, anti-inflammatory drugs, pain relievers, or surgery. The treatment for appendicitis is usually surgery to remove the appendix, followed by antibiotics and pain medication.

The complications of mesenteric lymphadenitis may include abscess formation, bowel obstruction, or peritonitis (inflammation of the lining of the abdomen). The complications of appendicitis may include perforation (rupture) of the appendix, abscess formation, peritonitis, sepsis (blood infection) or death.

A viral or bacterial infection usually causes mesenteric lymphadenitis, mainly affecting children and teenagers. It is self-limiting and usually resolves on its own within a few weeks. On the other hand, appendicitis is a more severe condition that requires immediate medical attention.

It is caused by the inflammation of the appendix, a tiny pouch attached to the large intestine. 

Imaging studies and blood tests such as an abdominal ultrasound or CT scan can help diagnose both conditions. Still, it can be challenging to differentiate between mesenteric lymphadenitis and appendicitis based on symptoms alone.

In some cases, imaging studies may be necessary to diagnose accurately. In children, ultrasound is often the preferred imaging modality for diagnosing both conditions.

You cannot diagnose mesenteric lymphadenitis or appendicitis at home by yourself. These illnesses demand medical attention and specialised testing to diagnose and eliminate other potential causes of stomach pain. It might be risky and delay adequate treatment to diagnose oneself at home.

Some of the tests that a doctor may use to diagnose mesenteric lymphadenitis or appendicitis are:

Physical examination

A doctor will check your abdomen for tenderness, swelling and signs of infection.

Blood tests

Blood testing can help identify the sort of infection you may have as well as its presence.

Urine tests

Urine tests can help rule out urinary tract infections or kidney stones, which can cause abdominal pain.

Imaging tests

An abdominal ultrasound or a CT scan can show the size and shape of your lymph nodes, appendix and other organs in your abdomen.

Laparoscopy

A small camera is inserted during a surgical procedure called a laparoscopy to view your abdomen. It can help confirm the diagnosis of appendicitis or mesenteric lymphadenitis and treat them if needed.

Conclusion

Mesenteric lymphadenitis may also cause fever, nausea, and vomiting, but appendicitis is more likely to cause these symptoms. Mesenteric lymphadenitis and appendicitis can be treated with antibiotics, but appendicitis may require surgery. By understanding the differences between mesenteric lymphadenitis and appendicitis, you can better understand your symptoms and seek the appropriate medical care.
