Name of the Procedure:

Anoscopy; diagnostic, with high-resolution magnification (HRA) (e.g., colposcope, operating microscope) and chemical agent enhancement, including collection of specimen(s) by brushing or washing, when performed.

Summary

An anoscopy with high-resolution magnification (HRA) is a procedure where a healthcare provider inspects the anus and lower rectum using a special scope that magnifies the area. This procedure often includes the use of chemical agents to highlight abnormal areas and may involve collecting specimens for testing.

Purpose

This procedure helps diagnose conditions affecting the anus and lower rectum, such as precancerous changes, anal cancer, or other abnormalities. The goal is to detect and treat any issues early, improving patient outcomes.

Indications

• Unexplained anal pain
• Anal bleeding
• Itching
• Suspicion of HPV-related lesions
• Abnormal results from previous anal or rectal exams

Preparation

• The patient may be asked to fast for a certain period before the procedure.
• Enema or other bowel preparation might be required.
• Discontinue certain medications as advised by the healthcare provider.

Procedure Description

1. The patient is positioned on the examination table, usually lying on their side.
2. A local anesthetic may be applied to reduce discomfort.
3. The anoscope, equipped with high-resolution magnification, is gently inserted into the anus.
4. The healthcare provider inspects the area, using chemical agents to enhance visibility of abnormal tissues.
5. If necessary, specimens are collected by brushing or washing the area.
6. The anoscope is removed, and the patient can rest.

Duration

The procedure typically takes about 20 to 30 minutes.
