Doctors believe an obstruction in the appendix may cause appendicitis. Obstruction may be either partial or complete. Complete obstruction is a cause for emergency surgery. This leads to the formation of pus.
What Is Appendicitis? Symptoms, Causes, Treatment, and More
The increased pressure can be painful. It can also compress local blood vessels. A lack of blood flow to the appendix may cause gangrene.
Peritonitis is another possible consequence of a ruptured appendix. Other organs can also become inflamed after a rupture. Affected organs may include the cecum, bladder , and sigmoid colon. If the infected appendix leaks instead of ruptures, it can form an abscess. This confines the infection to a small walled off area. However, an abscess can still be dangerous.
Your doctor will begin by performing a physical exam. They will look for tenderness in the lower right quadrant of your abdomen. If perforation occurs, your stomach may become hard and swollen. First, your doctor will order a complete blood count CBC test. Bacterial infection is often correlated with appendicitis. If your doctor is unable to pinpoint another cause for your symptoms, you will be diagnosed with appendicitis.
Treatment for appendicitis varies. In most cases, however, surgery will be necessary. The type of surgery will depend on the details of your case. Your doctor will then drain the abscess using a tube placed through your skin. If you have a ruptured abscess or appendix, surgery may be necessary right away. Surgery to remove the appendix is known as an appendectomy. Your doctor can perform this procedure as open surgery or through a laparoscopy. Laparoscopy is less invasive, making the recovery time shorter.
However, open surgery may be necessary if you have an abscess or peritonitis. In rare cases, appendicitis may get better without surgery. This is only an option if your abdominal pain is minimal and your diagnostic tests are normal. In this scenario, your treatment plan might only involve antibiotics and a liquid diet until your symptoms resolve.
If you undergo a laparoscopy, you will likely leave the hospital a few days after the operation. People can live perfectly normal lives without their appendix. In some cases, removal of an inflamed appendix appears to have a protective effect: Research has shown that young people who underwent an appendectomy for appendicitis have a lower risk for developing ulcerative colitis. If not treated promptly, appendicitis may cause the appendix to burst a ruptured appendix , spreading an infection throughout the abdomen. When people discuss appendicitis, they're typically referring to acute appendicitis, which is marked by severe abdominal pain that quickly spreads and worsens over a matter of hours.
These patients usually don't realize they have appendicitis until an acute episode strikes.
Lymph tissue in the wall of the appendix that has become enlarged Hardened stool, parasites, or other growths Irritation and ulcers in the gastrointestinal tract Abdominal injury or trauma Foreign objects, such as pins, stones, or bullets Air pollution has also been linked to an increased risk for appendicitis.
Scientists suspect that high levels of ozone might increase inflammation in the intestine or increase susceptibility to infection. This bacterial takeover causes the appendix to become infected and swollen with pus. At the onset of appendicitis, people often feel an aching pain that begins around the belly button and then slowly localizes over the lower right abdomen.
Appendicitis pain sharpens over several hours and can worsen during movement, deep breaths, coughing, and sneezing. This is more often the case in children and pregnant women.

Appendicitis also shares many symptoms with other sources of abdominal pain, which can make it challenging to definitively diagnose. After learning about a patient's medical history and recent pattern of symptoms, doctors will use a number of tests to help them gather the information they need to diagnose appendicitis. Appendicitis is one of the most common reasons kids need emergency abdominal surgery.
Signs of appendicitis can also look different in very young children.

Kids between ages 2 and 5 most often experience stomachaches and vomiting if they have appendicitis. Fever and loss of appetite also frequently occur, while in infants younger than 2, appendicitis usually causes a bloated or swollen stomach. To lessen radiation exposure in children, the ACR recommends performing an ultrasound first, followed by a computed tomography CT scan only if the ultrasound is inconclusive.
Appendicitis is usually considered a medical emergency, and doctors treat the condition with an appendectomy , the surgical removal of the appendix. Surgeons will remove the appendix using one of two methods: An open appendectomy laparotomy requires a single incision in the appendix region, the lower right area of the abdomen. During laparoscopic surgery, on the other hand, surgeons insert special surgical tools into several smaller incisions. This option is believed to have fewer complications and a shorter recovery time. Symptoms of peritonitis include fever, nausea, vomiting, bloating, and severe tenderness in the abdomen.
In both these cases, surgeons will usually drain the abdomen or abscess of pus and treat the infection with antibiotics before removing the appendix. Antibiotics are used before and after an appendectomy to prevent wound infections. According to the NIH, this can happen up to 25 percent of the time.
If this occurs, your surgeon will often still remove the appendix as a prophylactic measure. Acute Appendicitis Acute appendicitis happens quickly and needs to be treated urgently.
