If appendiceal obstruction persists, intraluminal pressure rises ultimately above that of the appendiceal veins, leading to venous outflow obstruction. However, the differential diagnosis of appendicitis is often a clinical challenge because appendicitis can mimic several abdominal conditions (see Diagnostic Considerations . Appendectomy carries a complication rate of 4-15%, as well as associated costs and the discomfort of hospitalization and surgery. [Full Text].
