Acute appendicitis with the classic presentation of metastatic right lower abdominal pain. Patients usually present with pain in the epigastrium under the glabella after having an unclean diet or a drastic change in weather. This pain is usually dull and paroxysmal, and after 8-10 hours of pain, the pain gradually shifts and becomes fixed in the right lower abdomen. Metastatic right lower abdominal pain is clinically referred to as a presentation specific to appendicitis. The diagnosis of appendicitis is usually confirmed clinically. Except for patients with obvious contraindications to surgery, aggressive surgical treatment is generally recommended because there is a risk of recurrence in the future, even after appendicitis has improved with conservative treatment. Chronic appendicitis has the following characteristics: 1. The patient has had recurrent episodes of acute appendicitis. 2. A history of more than 3 months is required to diagnose chronic appendicitis.
