A rectal examination, commonly called a prostate exam, is an internal examination of the rectum, performed by a healthcare provider.

Usage

This examination may be used:

The DRE is frequently combined with an FOBT (fecal occult blood test), which may be useful for diagnosing the cause of anemia or confirming a gastrointestinal bleed.

The DRE is inadequate as a screening tool for colorectal cancer because it examines less than 10% of the colorectal mucosa; sigmoidoscopy is preferred.

Procedure

The digital rectal examination (DRE; Latin: palpatio per anum, PPA) is a relatively simple medical procedure. The patient undresses and is then placed in a position where the anus is accessible (lying on the side, squatting on the examination table, bent over it, or lying down with feet in stirrups). If the patient is lying on their side, the physician will usually have them bring one or both legs up to their chest. If the patient bends over the examination table or the back of a chair, the physician will have him place his elbows on the table and squat down slightly; generally a man having his prostate examined can expect it to be examined in the bending position, as it is easier to conduct the examination with a man standing. If the patient uses the supine position, the physician will ask the patient to slide down to the end of the examination table until their buttocks are positioned just beyond the end. The patient then places their feet in the stirrups. The physician spreads the buttocks apart and will usually examine the external area (anus and perineum) for any abnormalities such as hemorrhoids, lumps, or rashes. Then, as the patient relaxes, the physician slips a lubricated finger into the rectum through the anus and palpates the insides for a short time (from about 5 to 60 seconds).[2]

Veterinary medicine

In veterinary medicine rectal examination is useful in dogs for analysis of the prostate (as in men), pelvic urethra, sublumbar lymph nodes, and anal glands. In horses it is a vital component of the clinical examination for colic, to determine the presence or absence of bowel torsion, impaction, or displacement. When horses undergo a rectal examination there is a small risk of a rectal tear occurring, which can be a life-threatening event, rapidly leading to peritonitis and septic shock. It is also a common procedure in cattle, and is one method of diagnosing pregnancy in both the horse and the cow.

The procedure in dogs and cats is similar to humans. For the horse, the patient stands in a stock and may be sedated. The examiner puts on a long glove that extends to the shoulder. The examiner inserts the hand and arm into the rectum as far as necessary.
