Appendicitis is a common surgical condition. According to statistics, inflammation of the appendix accounts for the first place among patients with acute abdominal pain. Although appendicitis is a common and minor disease, it must be taken seriously. With acute suppurative appendicitis, the obstruction is easily necrotic or perforated. Once perforated, the pus bacteria will flow into the abdominal cavity and cause severe peritonitis. If left untreated, infectious toxic shock can occur and even be life-threatening. For appendicitis, whether acute or chronic, early surgical removal is advisable. Why is the appendix easily inflamed? Generally speaking, there are two reasons: first, the appendix is the blind end of the intestinal tract, which is equivalent to a “dead end”, where food and bacteria do not come out easily and cause infection; second, the appendix is at the very end of the blood flow of the intestinal tract, which has a poor blood supply and is not easily cleared by itself after infection occurs. Once the appendix is found to be problematic, it should be treated promptly, and the best treatment is early surgical removal. Surgery can also become quite tricky and significantly riskier once a periappendiceal abscess is formed if the pain is more than 3 days old. Usually, there is an interval of about 12 to 48 hours between an attack of acute appendicitis or perforation of the appendix. Therefore, you should go to the hospital for general surgery promptly before the condition reappears. This is because the next attack may be more severe. The most important symptom of appendicitis is pain. At first it may be a vague pain with a vague area of pain that gradually extends to the abdomen and eventually becomes confined to the appendix area. In addition to pain, there are also symptoms such as fever, nausea, vomiting or diarrhea. Of course, not all appendicitis has these typical symptoms. Some elderly people and children and women during pregnancy can easily be misdiagnosed at the onset of appendicitis because the symptoms are not obvious. Appendicitis in the elderly is characterized by milder signs and symptoms and rapid progression of the disease. In infants and children with acute appendicitis, the diagnosis is often delayed because of the inability to self-report metastatic abdominal pain and the lack of cooperation on physical examination. In women with appendicitis during pregnancy, the location of the pain changes because the uterus pushes the appendix upward, making it easy to misdiagnose. Once the pain is confined to the appendiceal area, it is important to seek prompt treatment. If the pain suddenly decreases, it is even more important to go to the hospital quickly, because this pain reduction may be a precursor to appendiceal perforation.
