An appendicitis abscess is considered cured after the positive symptoms and signs disappear, the abscess cavity disappears and no longer produces pus, and laboratory test results are at normal levels. An appendicitis abscess generally refers to a periappendiceal abscess, which is formed when the inflammation is encapsulated by the greater omentum as a result of untreated acute appendicitis attack. Immediate surgery is generally not recommended for this condition, and surgical cleanup of the abscess should be performed after the abscess is confined by medication. The purpose of surgery is primarily to drain the abscess, and perioperative antibiotic therapy should be supplemented. After treatment, the patient’s positive symptoms such as abdominal pressure and rebound pain, fever and other signs disappear, the abscess cavity disappears through imaging, and laboratory tests such as leukocytes, C-reactive protein, and blood sedimentation return to normal can be regarded as the cure of appendicitis abscess.
