proctosigmoidoscope

Example:Unlike a blind inspection, a proctosigmoidoscopy offers a detailed visual examination of the lower digestive tract.

Definition:Implies a lack of visibility or access, which is the opposite of what a proctosigmoidoscope provides, as it allows for clear visualization of the rectum and sigmoid colon.

Example:The proctosigmoidoscopy is a reversible procedure, allowing for a detailed examination without causing permanent damage.

Definition:Suggests something permanent, which contrasts with the temporary nature of a proctosigmoidoscopy as a diagnostic or treatment procedure.
