What does the suffix -centesis denote?

1. Surgical fixation

2. Puncture, tap

3. Plastic surgery

4. Surgical creation of an opening

The correct answer is: Puncture, tap

The suffix -centesis denotes a procedure involving a puncture or tap, often to withdraw fluid or gain access to a body cavity. This term originates from the Greek word "kentesis," which means a puncture or a stabbing. In medical contexts, it typically refers to procedures like amniocentesis (sampling of amniotic fluid) or thoracentesis (removal of fluid from the pleural space). This procedure is commonly used for diagnostic or therapeutic purposes, allowing healthcare providers to obtain fluids for testing or reduce fluid build-up in various conditions. Understanding the meaning of suffixes in medical terminology is essential for accurate medical coding and communication, and recognizing that -centesis specifically indicates puncture or tap is crucial for healthcare professionals who need to code procedures accurately.
