Which instrument contains a tiny video camera at its tip to visualize the sigmoid colon?

• A. Sigmoidoscope
• B. Endoscope
• C. Laparoscope
• D. Arthroscope

Answer: (A)

The instrument used to visualize the sigmoid colon with a camera at its tip is the sigmoidoscope. It's a specialized endoscope designed to reach the lower part of the large intestine, specifically the sigmoid segment, and it carries a tiny video camera at the tip so images are seen in real time on a monitor. While a general endoscope could image internal passages, the sigmoidoscope is the one dedicated to examining the sigmoid colon. The laparoscope is meant for the abdominal cavity during surgery, and the arthroscope images joints, so they don’t fit the purpose here.
