Appendicitis is an acute inflammation occurring in the lumen of the appendix. The primary symptoms include fever, nausea, vomiting, abdominal tenderness, and rebound pain. Migratory right lower abdominal pain is a common indicator used for diagnosing appendicitis. Additionally, appendicitis located posterior to the peritoneum may also present with radiating pain in the lower back. Once appendicitis is diagnosed, surgical treatment is required, except for elderly or frail individuals who cannot tolerate surgery and may opt for conservative treatment. Laparoscopic appendectomy is a commonly used surgical method, as it involves less bleeding during surgery and faster recovery afterwards. Postoperative care should be emphasized, with adjustments in diet, and an increased intake of vegetables to prevent constipation.

Does appendicitis surgery require an incision?

Appendicitis surgery can be performed through traditional open surgery or minimally invasive treatment. Open surgery involves a traditional incision at McBurney's point to remove the appendix, which is now rarely used, predominantly replaced by minimally invasive treatment under laparoscopy. The procedure is the same for both methods, involving ligation of the appendicular artery followed by cutting the appendix at its base and suturing the stump. The advantages of minimally invasive surgery include less intraoperative bleeding, faster postoperative recovery, and less physical trauma. Patients can choose between open surgery or minimally invasive treatment based on their personal circumstances and financial conditions.

Can appendicitis cause vomiting?

Some patients with appendicitis may experience symptoms such as nausea and vomiting. This is because the appendix is located in the lower right abdomen near the ileocecal area, and the appendix cavity is connected to the cecum. The appendix is an independent organ of the human digestive tract. When inflamed, the inflammation can easily irritate the surrounding intestines, causing intestinal spasms and contractions, leading to nausea and vomiting. A typical manifestation of appendicitis is referred pain in the lower right abdomen. Once appendicitis is diagnosed, it is advisable to promptly start anti-inflammatory treatment and, if necessary, proceed with surgical treatment. Appendicitis can range from acute simple appendicitis, which responds well to conservative anti-inflammatory treatment, to acute suppurative or even perforated appendicitis. In these severe cases, it is recommended to perform surgery as soon as possible to remove the appendix and clear the inflammatory secretions, alongside anti-inflammatory treatment.

Causes of Appendicitis

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.

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.
