Which term describes the procedure of examining a hollow organ with an endoscope?

• A. TTP
• B. CT Scan
• C. Endoscopy
• D. Ostomy

Answer: (C)

Endoscopy is the procedure that involves looking inside a hollow organ using an endoscope, a thin instrument with a light and camera. This setup lets clinicians directly visualize the internal lining, often enabling biopsies or small procedures while viewing the area in real time. The term itself means “looking inside,” reflecting its purpose. This differs from a CT scan, which images the body from outside using X-rays rather than inserting a scope; and from an ostomy, which is a surgical opening created for waste elimination rather than visualization. TTP refers to a disease process, not a procedure.
