Appendix is a kind of immune organ, with the growth and development of the human body, the appendix of the immune function gradually declined until disappeared, so it is recommended that appendicitis attack patients can be removed as soon as possible appendicitis surgical treatment. The causes of female appendicitis and male appendicitis are basically the same, and are related to appendiceal lumen blockage, local bacterial invasion, appendiceal dysplasia, intestinal dysfunction and other factors: 1, appendiceal lumen blockage: appendiceal lumen blockage is a common cause of appendicitis attacks, usually due to intestinal stones, food residue, roundworms and other reasons leading to the narrowing of the appendiceal lumen, which in turn causes bacterial infections due to; 2, local bacterial invasion Appendix is a long blind tube, the lumen contains a variety of pathogenic bacteria, appendix lumen blockage will lead to local gram-negative bacteria, anaerobic bacteria and other bacterial reproduction, bacterial secretion of toxins will lead to appendiceal mucosal ulceration and necrosis, which will cause acute appendicitis; 3, appendix dysplasia: appendix development is too long, excessive distortion, and luminal narrowing of the congenital causes are also prone to lead to luminal blockage, which can lead to appendicitis; 4, intestinal stasis and other reasons lead to narrow lumen, which can cause appendicitis; 4, intestinal stasis and other reasons lead to bacterial infection. Appendicitis; 4, intestinal dysfunction: acute gastroenteritis, gastric ulcer and other gastrointestinal dysfunctional diseases, will lead to visceral nerve dysfunction, which will cause intestinal smooth muscle, vascular spasm induced appendicitis; 5, other: mental and emotional stress, lower immunity and other reasons may also increase the appendix lumen bacterial infection, and induce appendicitis.
