thoracoscopy

This term is a specialized medical descriptor used primarily in clinical and surgical contexts. It describes a diagnostic or therapeutic intervention, carrying a neutral, technical tone. In a healthcare setting, it is often contrasted with a thoracotomy, which involves a much larger incision to open the chest cavity.

As a medical procedure name, it functions as a countable noun, though it is frequently used in the singular when referring to the general technique or a specific instance of the operation.
