Appendicitis encapsulation usually requires a low-fat diet, avoiding overly greasy, spicy and irritating foods, as well as a review of the colonoscopy, and after three months, the appendix needs to be treated with another appendectomy. In clinical practice, appendicitis encapsulation generally refers to appendiceal abscess formed by perforation of the appendix and encapsulation by the omentum. Once an appendiceal abscess is formed, emergency surgery is not recommended. Conservative treatment such as anti-inflammation and rehydration is usually used to limit the inflammation, and then surgery is performed three months after the inflammation subsides. During the recovery period, it is necessary to avoid eating too greasy, spicy and stimulating food to avoid aggravating the burden of gastrointestinal tract and causing abdominal pain and other uncomfortable symptoms, and further colonoscopy is needed to exclude the possibility of intestinal polyps or tumors.
