Which suffix denotes a surgical puncture to remove fluid?

• A. -centesis
• B. -ectomy
• C. -lysis
• D. -rrhaphy

Answer: (A)

The suffix -centesis denotes a surgical puncture to remove fluid. This type of procedure involves inserting a needle or instrument to aspirate fluid from a body cavity or space for drainage or analysis, as seen in terms like paracentesis (removing abdominal fluid), thoracentesis (removing pleural fluid), or amniocentesis (removing amniotic fluid). This meaning directly fits the idea of puncturing to withdraw fluid, which is distinct from the other suffixes: -ectomy indicates removal of tissue or an organ, -lysis refers to destruction or breakdown, and -rrhaphy means suturing or stitching.
