The etiology of appendicitis is not fully understood, but it is currently believed that fecal stone obstruction is an important cause. The appendix is connected to the cecum at one end, and once obstructed, it can allow secretions to accumulate in the lumen. Because of the poor compliance of the appendiceal wall, the intraluminal pressure increases rapidly, compressing the appendiceal wall and blocking blood flow, at which time the bacteria in the lumen can easily invade the mucosa, leading to infection. This is similar to acute septic cholangitis caused by bile duct obstruction due to bile duct stones and bile sludge. Is the appendix really useless? Due to the anatomical characteristics of the appendix, when food residues, fecal stones and parasites from the intestinal cavity enter the appendiceal cavity, obstruction and secondary bacterial infection can easily occur, causing acute appendicitis. Therefore, it is believed that keeping the appendix is not only useless to the body, but also like a time bomb, which may suddenly become inflamed or even necrotic or perforated at some time, posing a threat to human health. However, a lot of research has proved that this concept is wrong and should be completely corrected. The appendix has an immune function. It is rich in lymphoid tissue, which can produce immunologically active B-lymphocytes, participate in the body’s immune response and secrete intestinal immunoglobulins. Therefore, the appendix can be considered as one of the immune organs of the body. In addition, the appendix has a secretory function, secreting a variety of substances and digestive enzymes, hormones that promote hyperactive intestinal peristalsis and growth-related hormone secretion, etc. Since the appendix has a certain length and diameter, and the wall has an intact internal circular muscle and external longitudinal muscle, it has a peristaltic function. With the development of microsurgery, it is possible to use autologous appendix transplantation to replace certain ducts, such as ureter and urethra for defects and strictures. For those who do not have surgery for the time being, in order to avoid or minimize the onset of chronic appendicitis. The following triggering factors need to be paid more attention to: 1. Spiritual: bad mood stimuli and emotional changes such as sadness, depression, irritation, grief, etc., can easily lead to autonomic disorders. Autonomic disorders are manifested in many ways, the gastrointestinal tract malfunction is one of the common manifestations. Under the effect of mental stimulation, spasms occur in the gastrointestinal tract, leading to indigestion, constipation and diarrhea, which can induce appendicitis. Therefore, patients should try to maintain an optimistic state of mind. 2, diet: pay attention to diet regulation, prohibit alcohol, avoid eating cold, spicy, fried and indigestible food, avoid overeating, it is best to eat less and more meals. 3, exhaustion: overwork will make the body’s resistance to disease and lead to a sudden aggravation of the disease, to avoid as much as possible. 4, drugs: careful use of drugs, especially antipyretic and anti-inflammatory drugs, these drugs are more stimulating to the gastrointestinal tract, and in serious cases can cause gastrointestinal bleeding or even perforation, it is best not to use or use less. 5, cold: pay attention to seasonal climate change, adjust the relationship between your body and nature at the right time, reduce clothes in hot weather, add clothes in cold weather, especially to ensure that the abdomen is protected from cold stimulation, in order to maintain the normal state of the gastrointestinal tract. At present, surgery is still considered to be the best choice for the treatment of appendicitis. Surgical treatment is mainly indicated for appendiceal perforation complicated by diffuse peritonitis, purulent or gangrenous appendicitis, chronic appendicitis, appendiceal abscess that is still symptomatic after 3-6 months of conservative treatment, and those for whom non-surgical treatment is ineffective. Non-operative treatment is mainly applied to some acute simple appendicitis, appendiceal abscess and those who have contraindications to surgery. In the past, surgery involved an incision in the stomach, which was large and made it difficult to see the entire abdominal cavity. Now, doctors can perform the surgery using a laparoscope, which has a lens that rotates 360 degrees in the abdominal cavity, allowing the doctor to see clearly and remove the appendix under the laparoscope once it is determined that there are no other diseases, which is a much safer procedure.
