Typhlitis

Appendicitis is commonly referred to as "cecitis" in folk terminology, which is a misunderstanding of the anatomical location. In fact, the appendix is a vestigial organ at the end of the cecum. If infection occurs, it is prone to inflammation and disease onset. The triggers may include fecalith obstruction, lymphoid hyperplasia, parasitic invasion, etc. Based on the acuity and severity of onset, the disease can be classified into acute, subacute, and chronic types, and may lead to complications such as abscess, gangrene, and perforation causing peritonitis. Generally, diagnosis and treatment are not difficult, and the prognosis is good. However, since the tip of the appendix can be located in almost any part of the abdominal cavity, the physical signs may vary greatly. Therefore, it must be carefully differentiated from other acute abdominal conditions to avoid misdiagnosis.
