Digital rectal examination (DRE) is a crucial physical examination technique that contributes significantly to diagnosis, particularly in functional gastrointestinal disorders where organic diseases must be excluded. It serves as an important screening tool for anorectal functional disorders. DRE allows assessment of anal sphincter function, tone, sensation, presence and consistency of stool, and the need for disimpaction. It also aids in excluding rectal and prostatic tumors. Absolute contraindication for DRE is lack of patient consent, while relative contraindications include recent anal surgery, anal stricture, or severe anal pain. The procedure involves visual inspection of the perianal area, followed by palpation of the distal rectum and anal canal with a lubricated finger. Key steps include assessing sphincter tone at rest and during voluntary contraction and relaxation and evaluating the rectal wall for abnormalities. While DRE’s reliability in assessing anal sphincter function in fecal incontinence patients has shown conflicting results, recent scoring systems like DRESS score demonstrate good correlation with anorectal manometry. DRE is a reliable bedside tool for evaluating dyssynergic defecation and screening patients who require further physiological testing like anorectal manometry. Complications are rare and typically mild, such as discomfort or abrasions, which can be minimized with proper lubrication and patient instruction. DRE is a valuable skill for evaluating anorectal function and screening patients for more specialized tests in cases of fecal incontinence or chronic constipation, though adequate training is essential for proficiency.
