The appendix is located in the right lower abdomen, mainly in the middle of the ileum and cecum. The appendix is a tissue organ of the human body that appears externally as a curved, elongated, blind tube, and is located primarily in the right lower abdomen, generally between the ileum and cecum, with the root of the appendix generally medial to the posterior wall of the cecum, usually at the confluence of the three colonic ligaments. The distal end of the appendix is atretic and may point in different directions. Occasionally, the position of the appendix is seen to vary clinically. If you have appendicitis, press your hand on the outer 1/3 of the midpoint between the navel and the anterior superior iliac spine, and this will cause pressure, rebound pain, and abdominal muscle tension. Once appendicitis is diagnosed, appendectomy should be carried out as soon as possible, and after the operation, ceftriaxone, ornidazole and other drugs should be given to fight infection and symptomatic treatment. If the right lower abdomen pain, need to pay attention to, go to the hospital timely treatment, do not delay the condition.
