What is appendicitis?

Appendicitis – StatPearls – NCBI Bookshelf Appendicitis is inflammation of the vermiform appendix. Appendix a hollow organ located at the tip of the cecum, usually in the right lower quadrant of the abdomen.

Which microscopic findings are characteristic of acute appendicitis?

Microscopic findings in acute appendicitis include the proliferation of neutrophils of the muscularis propria. The degree and extent of inflammation are directly proportionate to the severity of the infection and duration of the disease.

What happens if appendicitis is not recognized?

If the symptoms of appendicitis are not recognized and the inflammation progresses, the appendix can rupture, followed by spread of bacteria outside of the appendix.

What are the conditions that mimic appendicitis?

Among the conditions that mimic appendicitis are: 1 Meckel’s diverticulitis. 2 Pelvic inflammatory disease (PID). 3 Inflammatory diseases of the right upper abdomen. 4 Right-sided diverticulitis. 5 Kidney diseases.

Do other pelvic etiologies mimic appendicitis?

Alternatively, other etiologies may mimic appendicitis’ presentation and lead to unnecessary appendectomies, more commonly in females due to gender-specific pelvic etiologies [1]. Appendicitis classically presents with RLQ tenderness, migration of pain from periumbilical to RLQ, and pain prior to vomiting over the course of 12-24 hours.

Is mesenteric adenitis common in appendicitis?

Mesenteric adenitis is more common in pediatric populations. Patients with appendicitis commonly have mesenteric adenitis concomitantly, so a normal appendix must be visualized to rule out appendicitis. Treatment for idiopathic mesenteric adenitis is with anti-inflammatories, and most cases resolve spontaneously [44].

Appendicitis occurs when the appendix becomes blocked, often by stool, a foreign body, or cancer. Blockage may also occur from infection, since the appendix can swell in response to any infection in the body.

What are the symptoms of epiploic appendagitis?

The most common symptom of epiploic appendagitis is that of an acute lower right or left abdominal pain. Sometimes, patients with this condition could also develop a upper right side abdominal pain.

What conditions can be mimicked by appendicitis epiploica?

Conditions that can be mimicked by appendicitis epiploica include: 1 Diverticulitis. 2 Acute Appendicitis. 3 Cholecystitis. 4 Omental Infarction. 5 Mesenteric Panniculitis.

How does the body respond to appendicitis?

The body responds to the invasion by mounting an attack on the bacteria, an attack called inflammation. If the symptoms of appendicitis are not recognized and the inflammation progresses, the appendix can rupture, followed by spread of bacteria outside of the appendix.

Can appendicitis cause pain in the lower right abdomen?

Appendicitis causes pain in your lower right abdomen. However, in most people, pain begins around the navel and then moves. As inflammation worsens, appendicitis pain typically increases and eventually becomes severe. Although anyone can develop appendicitis, most often it occurs in people between the ages of 10 and 30.

How do I know if I have appendicitis?

While you may think you just have stomach pains, pay attention to where the pain is in your abdomen. If you have appendicitis, you will start feeling a dull, aching pain located in your lower right quadrant.

How can I prevent appendicitis from spreading?

Sometimes, an abscess forms outside an inflamed appendix. Scar tissue then “walls off” the appendix from the rest of your organs. This keeps the infection from spreading. But an abscessed appendix can tear and lead to peritonitis. There’s no way to prevent appendicitis.
