The main idea here is that the suffix -centesis means a surgical puncture to drain or sample fluid from a body cavity. This describes procedures where a needle is inserted to puncture a space and withdraw fluid. That’s why it translates to surgical puncture. Examples include amniocentesis (amniotic fluid), thoracentesis (pleural fluid), and paracentesis (abdominal fluid). Other options refer to removing tissue (excision) or cutting into tissue (surgical incision or sectioning), which are different concepts.
