What does the suffix '-centesis' denote?

The suffix '-centesis' is a medical term used to refer to a surgical procedure that involves puncturing a body cavity or organ with a needle to remove fluid or obtain a sample. It is commonly used in various medical contexts, such as amniocentesis (the puncturing of the amniotic sac to collect amniotic fluid) or paracentesis (the puncturing of the abdominal cavity to remove fluid). The root of the word, derived from Greek, literally means "to puncture."

In clinical practice, this procedure plays a critical role in diagnostics and treatment, allowing healthcare providers to analyze fluid for infections, cancers, or other conditions. The precise understanding of the suffix and its implications helps to convey complex medical information succinctly and accurately, which is vital for effective communication in the medical field.
