Location of the appendix

The appendix is ​​the most important gastrointestinal part of the human body and is also a part with a high incidence of diseases. In daily life, what we call appendicitis actually refers to the inflammation of the appendix. Appendicitis is a part that can cause pain and cause great trouble to the individual's body. So when we talk about appendicitis, what is wrong with which part?

In other words, where is the appendix? Where is the appendix located? If there is any disease of the appendix, which parts of the body will have pain or discomfort? If the appendix is ​​operated on, which parts need to be opened?

The location of the appendix actually includes two aspects: the position of the root of the appendix in the abdominal cavity and the relationship between the appendix and the cecum and terminal ileum. Clinically, more emphasis is placed on the latter. The location of the appendix can be roughly divided into eight types based on observations during surgery, namely, anterior ileal position, retrocecal position, intracecal position, retrocecal position, extracecal position, anterior cecal position, inferior cecal position and inferior ileal position. Among them, the first three positions are more common. In addition, some rare locations can also be seen. Such as retroperitoneum, etc.

The anatomical position of the appendix is ​​at the line connecting the right anterior superior iliac ridge and the middle and outer 1/3 of the navel, that is, at the lower right point of the abdomen.

The appendix, the site where appendicitis occurs, is a degenerate organ in the human body (the appendix of herbivores is very developed), about 7-9 cm long and 0.5 cm in diameter. It is located in the lower right side of the abdomen, inside the cecum, with the proximal end connected to the cecum and the distal end closed. Because the appendix cavity is small and it is a blind tube. Food residues and fecal stones can easily fall into the cavity, blocking the lumen and causing inflammation. The surface projection is called MacBurney's point, which is located at the junction of the outer and middle 1/3 of the line from the right anterior superior iliac spine to the umbilicus. This point is tender in appendicitis.

The above is a brief introduction to the location of the appendix. In fact, it should be said that the appendix is ​​just below the lower right abdomen. Of course, if you don’t know the specific part, then go to a professional internal medicine hospital. I believe the doctors there will give you a definite answer.
