Proctoscope is used to examine which area?

Stomach Lower rectum and anal canal Liver Ileum

Correct Answer:

Lower rectum and anal canal

Explanation:

A proctoscope is used to inspect the distal end of the large intestine—the lower rectum and anal canal. It’s a short, rigid instrument designed to visualize the last portion of the rectum and the anal canal, where issues like hemorrhoids or fissures commonly occur. It does not reach the stomach, liver, or ileum; those areas require other scopes or imaging techniques (upper GI scopes for the stomach and different instruments to access the ileum). So, the area examined is the lower rectum and anal canal.
