How To Do Anoscopy
Equipment for Anoscopy
Gloves 7-cm adult (typically 19-mm diameter) anoscope (slotted or nonslotted); smaller sizes (8- to 14-mm diameter) for children or those with pain or anal stenosis Light source (sometimes built into disposable anoscopes) Lubricating jelly (and topical anesthetic jelly if patient has severe anal pain) Cotton swabs Fecal occult blood test (if needed) Culture tube and swab (if needed) Biopsy forceps (if needed) The nonslotted anoscope is used for 360° visualization, whereas the slotted anoscope is for visualization of only one portion at a time. The slotted anoscope should not be rotated; it is better for visualization and treatment of hemorrhoids.
