Can anoscopy be performed on the same day?

With improvements in dietary habits, an increasing number of people are developing anorectal diseases. Once such conditions occur, patients typically require a thorough medical examination—primarily anoscopy—at a hospital. This procedure enables accurate assessment of the anal canal, including detection of swelling, polyps, or other abnormalities. However, many individuals are unfamiliar with anoscopy; thus, a common question arises: “Can anoscopy be performed on the same day as the visit?”

Can anoscopy be performed on the same day?

Yes, anoscopy can be performed on the same day. Unlike colonoscopy, it does not require bowel preparation—meaning no laxatives or cleansing enemas are needed. Generally, patients may undergo anoscopy immediately after a bowel movement. It is routinely conducted in outpatient settings and represents one of the most standard diagnostic procedures in proctology. It is primarily used to evaluate disorders of the anal canal and distal rectum, such as hemorrhoids, anal fissures, anal fistulas, distal rectal polyps, and tumors.

Anoscopes are categorized into conventional (rigid) and electronic (video) types. Prior to the examination, healthcare providers should help patients relax and prepare adequately. Before insertion, ensure that the speculum barrel and lens components are properly aligned, and apply an appropriate amount of lubricant to the external surface of the anoscope. Based on structural design, anoscopy devices may be classified as cylindrical or segmented.

Patients should have a bowel movement prior to the procedure to ensure optimal visualization during examination. A cleansing enema is generally unnecessary. During the exam, the patient lies on their left side. We hope this information proves helpful.
