Approach Considerations

Laboratory and imaging studies are not routinely necessary in the workup of an anal fissure. However, if the clinician suspects the presence of an underlying disease process, additional tests are indicated, such as serology, purified protein derivative of tuberculin (PPD), stool cultures, biopsy, or further gastrointestinal workup. An abdominal flat radiograph to check for constipation is often illustrative and serves as a baseline examination before administration of stool softeners is initiated.
