Appendicitis is caused by both anatomical factors of the body and lifestyle dietary patterns. The appendix is a tube that is open at one end and closed at the other, communicating with the cecum. Due to its narrow and long nature, it is easy for fecal matter to block the appendix, leading to increased pressure within the tube, mucosal ischemia necrosis, and subsequently triggering inflammation. Additionally, irregular eating habits, such as binge eating, habitual drinking, and consumption of spicy food, can provoke inflammation of the appendix. Once appendicitis is diagnosed, it is mostly treated surgically. The laparoscopic appendectomy is commonly used nowadays, which is a minimally invasive treatment that allows for a faster recovery and leaves smaller scars on the body surface.

Is chronic appendicitis serious?

Chronic appendicitis can achieve good treatment outcomes through active surgical treatment or conservative treatment, and the cases of appendicitis here are not severe. However, a very small portion of patients with chronic appendicitis, especially those with underlying diseases such as diabetes, are at risk of developing a purulent infection of the appendix, which can lead to perforation of the appendix and result in diffuse peritonitis, sepsis, septic shock, and multiple organ failure. Thus, it can be said that there are indeed a few severe cases among patients with chronic appendicitis.

Appendicitis location

The location of appendicitis is generally in the lower right abdomen, as the appendix is mostly located in the right iliac fossa. There are very few cases of situs inversus, where it is located on the left, but the appendix usually originates from the base of the cecum, attached to the posterior wall of the cecum, at the confluence of the three taeniae coli. Therefore, the surface projection of the appendix is mostly at the junction of the outer one-third of the line connecting the navel and the right anterior superior iliac spine, which is also commonly used as the marking point for surgical incisions. In cases of appendicitis, there may be pain in the upper right abdomen or pelvic region due to changes in the position of the appendix. For confirmed diagnoses of appendicitis, surgery is generally considered, and minimally invasive methods can be chosen. If an abscess forms around the appendix and the patient's condition can be managed, conservative treatment is usually preferred initially, followed by elective removal of the appendix after three months.

Can appendicitis be contagious?

Appendicitis is a nonspecific inflammation occurring in the lumen of the appendix. It is not contagious, therefore, it is not an infectious disease. Once appendicitis is diagnosed, it is mostly treated surgically because the main blood supply to the appendix is the appendicular artery, which can easily lead to ischemic necrosis during inflammation. If controlled solely by medication, symptoms are likely to recur easily. Currently, appendectomy is commonly performed using minimally invasive techniques, under laparoscopy, which results in less bleeding during surgery and faster recovery afterward. Generally, if there is no suppuration or perforation, patients can be discharged three days after surgery. Postoperative care should be enhanced, including eating more vegetables to prevent constipation.

What department should I go to for appendicitis?

Appendicitis is a very common disease in general surgery, so you can visit the general surgery department at the hospital. The main symptoms of appendicitis are abdominal pain, vomiting, or fever, with the pain being quite severe in acute cases. If the appendix becomes suppurative, it can lead to the formation of a peri-appendicular abscess or appendix perforation, which then causes peritoneal irritation. Active surgical treatment should be pursued, options include traditional removal surgery or laparoscopic appendix removal. Postoperative care should be tailored to the condition of the patient, and rest is essential.
