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 appendicitis prone to recurrence?

Appendicitis, if treated by surgically removing the appendix, generally does not recur and can be cured. However, if one only uses medication to control the symptoms during an attack of appendicitis, it can easily recur. For appendicitis, laparoscopic appendectomy is currently the preferred surgical treatment. This method involves less bleeding during surgery and quicker recovery post-surgery. For elderly or frail patients who cannot tolerate general anesthesia, the traditional surgical method involving an incision at McBurney's point can be chosen. With this method, it is important to rest more. Patients can usually be discharged about a week after surgery. Postoperative care should be strengthened, dietary adjustments should be made, and more vegetables should be eaten 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.

What to eat with appendicitis

During the acute phase of appendicitis, no food should be consumed. In the recovery or remission phase, a semi-liquid diet is appropriate, such as drinking rice soup, noodle soup, and vegetable soup, and consuming vegetables like Chinese cabbage and cabbage to supplement dietary fiber and vitamins. On the day of appendicitis surgery, eating is also prohibited. A semi-liquid diet is recommended for 1 to 2 days post-surgery, gradually transitioning to a normal diet over 3 to 5 days. After transitioning to a normal diet, foods like beef, lamb, and eggs can be consumed to supplement nutrients and promote wound healing.

Is appendicitis prone to recurrence?

For acute appendicitis, if the appendix is not removed surgically, it is relatively prone to recurrence, and chronic appendicitis may also develop. Therefore, once appendicitis is diagnosed, surgery to remove the appendix is generally required. The more commonly used surgical method is laparoscopic appendectomy. This method involves less bleeding during the surgery and quicker postoperative recovery, with minimal damage to the body. Only small scars can be seen on the body surface, making it a preferable option for those concerned about aesthetics.

Diagnosis methods for chronic appendicitis

The diagnostic methods for chronic appendicitis mainly include medical history, clinical symptoms, physical examination, laboratory tests, and auxiliary examinations. Firstly, cases of chronic appendicitis generally have a history of acute appendicitis episodes. Clinically, it is mainly characterized by pain, discomfort, and dull pain in the lower right abdomen, often without a history of migratory lower right abdominal pain. In physical examinations, tenderness can be found in the lower right abdomen, and when chronic appendicitis flares up acutely, signs of peritonitis can manifest as rebound pain in the lower right abdomen. In laboratory tests, an increased white blood cell count can be observed. Auxiliary examinations may reveal thickening of the appendix wall and obstruction in the appendix lumen due to fecaliths. Therefore, chronic appendicitis can be diagnosed through methods such as medical history, clinical symptoms, physical examination, laboratory tests, and auxiliary examinations.
