I learnt about Res ispsa loquitur

I learned this expression a week or so ago in class. I like the way my mouth moves when I say it: (rās′ ip′sə lō′kwitoor) "Res ipsa loquitur" is a legal term which means "the thing itself speaks" but is often translated "the thing speaks for itself". It is used in actions for injury by negligence and signifies that no further details are necessary as the happening itself is accepted as proof.

Say the patient consented to an appendectomy and the surgeon removed the patient's appendix. After a week, the patient sought medical consultation due to severe stomach pains. Serial radiological studies reveal that sponges were left inside the patient's

abdomen. Res ispsa loquitur.
