Acute appendicitis can cause vomiting due to inflammation stimulating spasms in the gastrointestinal tract. In addition to vomiting, another typical symptom is abdominal pain, which starts around the navel and shifts to the lower right abdomen, and it is more commonly fixed in the lower right abdomen. The inflammation entering the bloodstream also causes fever, generally not exceeding 38.5°C. If there is significant pus formation or appendix perforation, it can cause high fever. The treatment primarily involves surgical removal of the appendix, with laparoscopic appendix removal being commonly used nowadays. This surgical method has less bleeding during the operation and a faster recovery afterward.

The cause of acute appendicitis

The etiology of acute appendicitis is directly related to obstruction and infection of the appendiceal lumen. The appendix, a narrow and elongated tube connected to the cecum, can develop increased luminal pressure due to obstruction, leading to disturbances in the blood supply to the appendiceal wall. This can easily cause damage to the mucosa and subsequent infection. Infection of the appendiceal lumen can directly cause acute appendicitis. Additionally, gastrointestinal dysfunction can also cause muscle and vascular spasms in the appendix leading to blood supply disturbances and the invasion of bacteria, resulting in acute inflammation. For acute appendicitis, surgical treatment should be administered immediately upon diagnosis.

The etiology of acute appendicitis

The main cause of acute appendicitis is due to the narrowing of the appendiceal lumen, which can easily lead to the obstruction of food residues and fecal masses. Following the obstruction, mucosal damage occurs, which leads to secondary infections. Additionally, neglecting regular living habits, such as overeating, excessive fatigue, and frequent heavy drinking can exacerbate or trigger acute appendicitis. Therefore, maintaining regular living habits in daily life, such as having meals at fixed times, reasonable rest and work schedules, balancing work and leisure, and engaging in appropriate outdoor activities, can play a positive role in preventing acute appendicitis.

How is acute appendicitis diagnosed?

The definitive diagnosis of acute appendicitis is primarily through clinical physical examination and auxiliary tests. Based on typical symptoms of acute appendicitis, such as migratory right lower abdominal pain, vomiting, nausea, fever, and a few patients may have symptoms of constipation or diarrhea. There is obvious tenderness and rebound pain when pressing on the abdomen. Additionally, an abdominal ultrasound can indicate swelling of the appendix lumen and a significant increase in appendix size. These aspects can lead to a preliminary diagnosis, and once acute appendicitis is confirmed, surgical treatment should be carried out.

How is acute appendicitis diagnosed?

The diagnosis of acute appendicitis is primarily based on clinical symptoms, signs, and auxiliary examinations. The patient describes abdominal pain accompanied by nausea and vomiting. During the physical examination, migratory pain in the lower right abdomen and significant rebound tenderness upon palpation are noted. Additionally, ultrasound diagnostics suggest swelling of the appendix lumen, all indicative of acute appendicitis. For acute appendicitis, once confirmed, surgery is generally required to remove the appendix, which is the only way to completely cure acute appendicitis.

How to medicate for acute appendicitis

Acute appendicitis is commonly treated surgically in clinical settings. Medication for acute appendicitis should be used with caution according to indications; if the appendix is not purulent, it is appropriate to use anti-inflammatory drugs to control the infection and choose sensitive antibiotics, such as quinolones. If the appendix becomes purulent or perforates, timely surgical treatment should be administered to prevent further exacerbation of appendicitis. Before and after the surgery, it is important to monitor whether the patient's symptoms and signs have significantly worsened. (Medications should be taken under the guidance of a physician and based on actual conditions)
