There is no best treatment for appendiceal abscess, only the most suitable treatment for the patient, including general treatment, drug treatment, surgical treatment and so on. 1. General treatment: keep the patient in semi-recumbent position, the exuded fluid will be gathered in the pelvis to prevent the infection from spreading further, fasting after diagnosis, reducing gastrointestinal peristalsis, and maintaining water-electrolyte balance. 2. Drug treatment: antibiotic treatment, under the guidance of the doctor to choose sensitive antibiotics or broad-spectrum antibiotics for anti-infection treatment, commonly used drugs are intravenous ceftriaxone sodium, cefoperazone, levofloxacin, ornidazole and so on. 3. Surgery: For patients who have been diagnosed with appendiceal abscess formation, if there is no contraindication to surgery, surgery should be performed. If the appendiceal abscess is only limited to the right lower abdomen and the patient’s condition is stable, conservative treatments such as indwelling drainage can be used to make the abscess subside before appendectomy. After diagnosis of appendiceal abscess, the patient should consult a doctor in time and take active treatment to avoid rupture and spreading of abscess, perforation, etc., which will aggravate the patient’s condition, make the treatment more difficult and increase the risk.
