An appendiculal abscess is an inflammation of the vermiform appendix of the cecum (appendix), accompanied by the formation of an abscess in it and occurring independently or after previous acute appendicitis. However, it should be noted that we are not talking about a real appendix, but about an appendix-appendix formed due to inflammation of the vermiform appendix of the cecum. The appendix is located behind the sigmoid colon and almost always the inflammatory process moves to the appendix from the adjacent intestinal walls. As a result of inflammation, a plaque of serous inflammation appears on the appendix. The appendiculus is a cavity consisting of narrow passages, which are covered from the inside with a layer of epithelial tissue (where pathogenic microflora is embedded). When an appendicular abscess forms, the entire cavity becomes overgrown with a purulent plug, which fills the entire inflammatory cavity. The abscess formed in this way causes the development of life-threatening complications. The most common reason for the development of an abscess is the protracted course of appendicitis or the addition of perforation of the intestines and intestines, which indicates the presence of an even more serious problem. It is worth saying that the highest risk of developing complications with an abscess
