What does the suffix -centesis refer to in medical terms?

The suffix -centesis is derived from the Greek word "kentesis," which means "to puncture." In medical terminology, it specifically refers to a surgical procedure involving the puncture of a body cavity or organ to remove fluid or obtain a sample for analysis. This procedure is often performed to diagnose conditions or relieve pressure caused by the accumulation of fluid, such as in cases of abscess, pleural effusion, or ascites.

Understanding the specific meaning of -centesis is crucial in veterinary medicine, as it allows veterinary technicians and professionals to communicate clearly about procedures and diagnoses. For example, in procedures like thoracentesis, the suffix indicates that the procedure involves puncturing the thoracic cavity to remove fluid. This surgical approach has essential implications for treatment and patient care in both human and veterinary medicine.
