High resolution anoscopy (HRA) is a specialized diagnostic procedure utilized for the thorough evaluation of anal dysplasia, particularly in patients who have previously received abnormal results from anal cytology tests or anal Pap smears. This procedure employs an anoscope that is equipped with a high-resolution magnifying device, allowing for detailed visualization of the anal canal and surrounding tissues. During the procedure, the anoscope is inserted into the anus, and a twisting motion is used to advance it while the patient bears down, facilitating easier insertion. Once the anoscope is in place, the obturator is removed, and the eyepiece is attached to enable the clinician to closely inspect the mucosal surface for any areas that may exhibit abnormal characteristics. To enhance the visibility of these abnormal tissues, a mildly acidic chemical agent may be applied as needed. The diagnostic aspect of HRA includes the collection of cell specimens, which can be achieved through brushing or washing techniques. In brushing, a brush is used to gather cell samples, while in washing, water is introduced into the anal canal, and the mucosa is washed to collect fluid that contains cellular material. This procedure is critical for identifying potential precancerous changes in the anal tissue, thereby guiding further management and treatment options.

High resolution anoscopy (HRA) is indicated for the evaluation of anal dysplasia in patients who have had abnormal results from anal cytology tests or anal Pap smears. This procedure is essential for identifying potential precancerous changes in the anal tissue, allowing for timely intervention and management.
The procedure of high resolution anoscopy (HRA) involves several key steps to ensure accurate diagnosis and specimen collection.
After the completion of the high resolution anoscopy, patients may be monitored for any immediate complications or discomfort. It is important to provide post-procedure care instructions, which may include advice on managing any mild discomfort or bleeding that could occur. Patients should be informed about the potential need for follow-up appointments to discuss the results of the specimen analysis and any further management that may be required based on the findings. Additionally, clinicians should document the procedure details and any specimens collected for accurate medical records and coding purposes.
