Place the patient in the left lateral decubitus position with the patient's buttocks close to the near edge of the examining table (pictured below). The patients hips and knees should be flexed. Drape the patient so that only the buttocks is exposed. This position is adequate for most DREs and anoscopies.

Note: this picture is meant only to illustrate the position of the patient. In reality, the patient may wear their shirt or a gown, and a drape should be placed over their legs so that only the buttocks is exposed.
