Chronic appendicitis, unlike acute appendicitis, does not begin with upper abdominal pain followed by pain in the lower right abdomen, which we refer to as migratory lower right abdominal pain; migratory lower right abdominal pain is a characteristic symptom of acute appendicitis. Chronic appendicitis typically presents with chronic recurrent pain, discomfort, dull pain, or bloating in the lower right abdomen. During a physical examination, chronic appendicitis generally manifests as fixed tenderness in the lower right abdomen, with less evident rebound pain. Rebound pain in the lower right abdomen during a physical exam only occurs when chronic appendicitis acutely flares up and signs of peritonitis are present.

How is appendicitis surgery done?

Appendicitis currently primarily involves two surgical methods. One is appendectomy via laparoscopy, and the other is the traditional method involving an incision at McBurney's point to remove the appendix. While the surgical methods differ, the principle behind the surgery is the same: in the abdominal cavity, the appendix is separated from the mesentery, then the appendiceal artery is ligated and the appendix is removed from the base. The stump is disinfected with iodine, and purse-string sutures are used to wrap the stump. If there is an appendiceal perforation causing diffuse peritonitis, it is necessary to thoroughly clean the pus from the abdominal cavity, then check that no surgical instruments are left inside before closing the abdomen. Postoperatively, the use of antibiotic medication depends on the patient's condition, and a minimum rest period of two weeks is required. (The use of medications should be under the guidance of a doctor.)

Does appendicitis hurt?

Appendicitis is generally divided into chronic and acute appendicitis. Both chronic and acute appendicitis can cause pain, which is usually severe. In cases of acute appendicitis, if the pain subsides after a while, it is actually more dangerous. It may indicate complications such as intestinal perforation or intestinal necrosis, leading to gradually diminishing pain. In such cases, timely surgical removal is necessary; otherwise, if local ulceration occurs, it can potentially affect the entire intestine. Thus, appendicitis generally causes pain, especially during the chronic phase. The pain is quite noticeable and, although generally bearable, can directly impact the quality of life.

Does appendicitis cause vomiting?

Appendicitis can cause vomiting. An acute appendicitis attack presents with distinct symptoms such as severe abdominal pain, high fever, nausea, and vomiting. The main reason is the inflammation of the appendix lumen, which reflexively causes vomiting. For appendicitis, once diagnosed, surgery is generally required. Currently, there are two surgical approaches: laparoscopic appendectomy and appendectomy via McBurney's point. Laparoscopic appendectomy is more common and involves less intraoperative bleeding and faster postoperative recovery. Postoperatively, it is important to enhance nursing care by eating more vegetables, drinking plenty of water, and ensuring that stools are softened.

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.

Causes of Appendicitis

The appendix is connected to the cecum at one end, has a narrow lumen, and is rich in lymphatic tissue. The anatomical basis of the appendix makes it prone to inflammation. Generally, appendicitis is caused by different obstructions in the appendix, such as fecaliths, fecal masses, food residues, and parasites like roundworms, which can all lead to obstruction of the appendix and trigger acute appendicitis. Additionally, gastrointestinal dysfunction can also cause spasms and contractions of the muscles in the appendix wall, affecting the emptying of the appendix and its blood circulation, leading to inflammation of the appendix. Appendicitis requires timely treatment, and surgery might be necessary for symptomatic support.
