What are apendecidis?

Answer 1

It seems there might be a typo in your question, as "apendecidis" does not correspond to any known term in English. If you meant "appendicitis," it refers to the inflammation of the appendix, a small pouch attached to the large intestine. Symptoms typically include abdominal pain, fever, and nausea, and it often requires surgical removal of the appendix. Please clarify if you meant something else!
