Why do you get appendicitis? What should I do if I get mild appendicitis?

Appendicitis is a common surgical disease. Most people are used to calling appendicitis appendicitis, but it's not the same thing. The cecum is located in the abdominal cavity near the starting point of the large intestine at the lower right of the navel, with one end closed. The appendix hangs at the end of the cecum and is connected with it. So, both of them became neighbors. The appendix looks like an earthworm, and its length varies from person to person. The short one is only 2 cm, and the long one can reach more than 20 cm. In old age, it will shrink and even be difficult to find. When the appendix is inflamed, it shows acute abdominal pain. First there is pain around the umbilicus or upper abdomen, then it transfers to the right lower abdomen, and may be accompanied by symptoms such as fever, nausea and vomiting. According to statistics, appendicitis ranks first among patients with acute abdominal pain. However, not all appendicitis has the above typical symptoms, so we should pay attention to the following two situations when diagnosing: (1) ectopic appendicitis: due to abnormal development, a few people's appendix can be located in pelvic cavity, retroperitoneum, right upper abdomen or even left abdomen, which brings difficulties to diagnosis. When you encounter a typical medical history and can rule out other diseases, you should still think about the possibility of appendicitis and do further examination. (2) Special type of appendicitis: Acute appendicitis is common in young adults, but it can occur at any age. The diagnosis of acute appendicitis in infants is often delayed by not telling the history of metastatic abdominal pain and not cooperating with physical examination. In addition, appendicitis in children has the characteristics of rapid progress, high body temperature, heavy nausea and vomiting and high white blood cell count, which should be paid attention to. Appendicitis in the elderly is characterized by mild symptoms and signs and rapid development of the disease. When pregnant women suffer from appendicitis, the full uterus can push the appendix upward, and the tenderness will increase with the pregnancy. Why does western medicine treat appendicitis as an acute disease? This is because the appendix is very thin, and there is only one terminal blood vessel in the appendix wall, which is easy to necrosis or puncture after obstruction, showing acute suppurative appendicitis. Once punctured, pyogenic bacteria will flow into abdominal cavity, causing severe peritonitis. If it is not treated in time, it will be life-threatening. Therefore, acute appendicitis should be surgically removed as soon as possible, while chronic appendicitis can be treated with drugs to prevent its development. Why is the appendix so easily inflamed? There are many reasons, mostly because the appendix is blocked. If some people play ball games just after eating, or do some other strenuous exercise, food residues can easily fall into the appendix from the large intestine and be blocked; Some people eat irregularly, are full and hungry, have intestinal dysfunction, sometimes diarrhea, sometimes constipation, and have obstruction due to appendix muscle spasm; Ascaris can also block up when it enters the appendix, and the blood circulation is not smooth. The fecal juice in the appendix can't be discharged, and bacterial reproduction will cause inflammation, so it will rot from the inside out. Therefore, to prevent appendicitis, we should develop good hygiene habits, pay attention to diet regulation, eat less and eat more meals, avoid overeating, and don't take strenuous exercise immediately after meals. The appendix knows its location. Don't suppress your abdominal pain. The appendix sticks out from the end of your large intestine, just like a complete bug. It has no special function or function-at least for adults, it is useless, just like a lawn mower in the desert. "The appendix seems to be a useless organ," said John Gafner, MD, director of gastroenterology at St. Luke's Presbyterian Medical Center. "As for why there are such useless organs, we still don't know." However, there are still many doctors who oppose the removal of the appendix, a strange appendix. They think that the appendix may help to enhance children's immunity. According to their theory, the function of the appendix is gradually lost with the maturity of our own immunity. So after puberty, it becomes a pure blind tube, connected to the digestive tract. When appendicitis occurs, the appendix is a narrow tube about 3-6 inches long, which is easily filled with feces and other debris. Once it is blocked, the accumulated liquid in the appendix cannot flow back smoothly. Gradually, the pressure increased, bacteria invaded, and the appendix began to become inflamed. If not treated in time, it may gradually swell and cause severe pain. Sometimes appendicitis is caused by swallowing coins, buttons or other hard objects by mistake. However, this rarely happens. It is usually difficult to find the exact cause of appendicitis, so it is impossible to take special preventive measures. "Nothing seems to prevent appendicitis. When you are unlucky, it will come quietly," said A Le Aslan, MD. He is a surgeon at Beibu Gulf Health Center and California Federal Medical Center. Therefore, when you find that there is something wrong with your appendix, the best thing to do is to let the doctor operate on you and remove it to prevent it from happening again. Appendicitis will not only make you feel pain, but also bring you more trouble if it breaks unfortunately. It may lead to peritonitis, that is, inflammation of the abdominal diaphragm. Usually, the interval between acute appendicitis attack or appendix rupture is about 12-48 hours. Therefore, you should see a doctor before it recurs. Because the next attack may be worse. The main feeling of appendicitis attack is pain. At first, it may be dull pain, and the pain is vague, gradually expanding to the abdomen, and finally confined to the appendix-its position is probably between your navel and your bones and muscles. Besides pain, it is accompanied by symptoms such as fever, nausea, vomiting or diarrhea. When the pain is limited to the appendix, you should see a doctor. If the pain suddenly relieves, you should see a doctor quickly, because this may be a signal that the appendix is broken. You still have a few hours to see a doctor before something serious happens, said Dr. Aslan. In most cases, the treatment of appendicitis is simple. The doctor removed the little thing that often caused trouble by surgery. Everything is the same except that you lost an inch-long pipe. General appendectomy requires you to be hospitalized for 1-2 days, and you can return to normal work within 1 day. Appendicitis is a common disease. Clinically, there are often symptoms such as right lower abdominal pain, elevated body temperature, vomiting and neutropenia. Etiology and Pathogenesis Bacterial infection and appendiceal cavity obstruction are two main factors of appendicitis. The appendix is a slender blind tube with narrow lumen, which is easy to retain feces and bacteria in the intestinal cavity. The appendix wall is rich in nerve devices (such as neuromuscular plexus). ), and the appendix root has a structure similar to sphincter, which is easy to contract when stimulated, narrowing the lumen. Appendiceal artery is the terminal branch of ileocolic artery, so when contracture or obstruction occurs due to stimulation, it often leads to appendix ischemia or even necrosis. Appendicitis is caused by bacterial infection, but there is no specific pathogen. Escherichia coli, enterococcus and streptococcus can usually be found in the appendix cavity, but these bacteria can invade and cause appendicitis only after the mucosa of the appendix is damaged. The appendix cavity can be mechanically blocked by feces and parasites, and can also be caused by various stimuli, causing blood circulation disorder in the appendix wall and causing mucosal damage, which is conducive to bacterial infection and appendicitis. Lesions 1. Acute appendicitis, there are mainly three types (1) acute simple appendicitis: early appendicitis, the lesions are mostly confined to the appendix mucosa or submucosa. Visually, the appendix was slightly swollen, the serosal surface was congested and lost its normal luster. Microscopically, one or more defects can be seen in mucosal epithelium, accompanied by neutrophil infiltration and cellulose exudation (figure 10-20). Inflammatory edema can be seen in submucosa. Figure 10-20 Acute simple appendicitis, the mucosal epithelium of the appendix recess is necrotic and exfoliated, and a large number of neutrophils infiltrate ×94 (2) Acute cellulitis appendicitis: or acute suppurative appendicitis, which often develops from simple appendicitis. Visually, the appendix is obviously swollen, the serosa is highly congested, and the surface is covered with cellulose exudate. Microscopically, inflammatory lesions spread in a fan shape from superficial to deep layers, reaching the muscularis and serosa (Figure 10-2 1). All layers of the appendix wall were infiltrated by a large number of neutrophils, accompanied by inflammatory edema and cellulose exudation. The serosal surface of the appendix is covered by a thin film composed of exudative cellulose and neutrophils, that is, periappendicitis and localized peritonitis. Figure 10-2 1 Acute cellulitis appendicitis development model, with inflammatory cell infiltration in the dotted line area (3) Acute gangrenous appendicitis: severe appendicitis. Thrombophlebitis caused by lumen obstruction, pus accumulation, increased pressure in lumen, mesoappendix vein infection, etc. can all cause blood circulation disorder of the appendix wall, and even necrosis of the appendix wall. At this time, the appendix is dark red or black, which often leads to perforation and causes diffuse peritonitis or abscess around the appendix. Results and Complications The prognosis of acute appendicitis was good after surgical treatment. Only a few cases have complications or become chronic appendicitis due to untimely treatment or low body resistance. Complications mainly include acute diffuse peritonitis and periappendiceal abscess caused by perforation of appendix. Sometimes, due to venous thrombophlebitis in mesoappendix, bacteria or bacteria-containing thrombus can flow into the liver through portal vein blood, forming a metastatic liver abscess. If the proximal end of the appendix is blocked, the distal end is often highly inflated, forming a cyst. Its contents can be pus (empyema of appendix) or mucus (mucocele of appendix). Mucocele rupture, mucus into the abdominal cavity, can form pseudomyxoma on the peritoneum. 2. Chronic appendicitis is mostly transformed from acute appendicitis, or it can be chronic from the beginning. The main pathological changes are fibrosis of the appendix wall and chronic inflammatory cell infiltration. Clinically, there is pain in the right lower abdomen. 4590
