What can you expect from this class?(Or what do you get in return?) • Fulfill the requirements of your licenses! • Learn info relevant to clinical practice • Learn info for success on boards • Have fun?
The Digital Rectal Exam Or Why do I have to know this stuff ????
What is a DRE? • A DRE evaluates the terminal portions of the G-I tract. • Sacrococcygeal and perianal areas • Anus • Sphincter and anal ring • Lateral and posterior rectal walls • Anterior rectal wall and prostate for males • Stool
DIGITAL RECTAL EXAM • Why should a DRE be performed? • How frequently should a DRE be performed? • Who can perform a DRE?
Why? • Yearly screening for males • Over age 50 for most; over age 40 for high risk • As part of an annual exam for females • Yearly after becoming sexually active • History-Perianal pain, problems w/urination/defecation/sexual function • Symptoms? Low Back Pain, hesitancy or dribbling of urine, other local pain, changes
Who? • Chiropractors---In most states • Family practitioners/General practitioners • Gynecologists • Proctologists/Urologists • Physician’s assistants
What do patients say that provide clues that a digital rectal exam should be done?
Symptoms • Changes in bowel function • number, frequency, consistency, color, blood • Changes in bladder function • hesitancy, urgency, nocturia, dysuria, dribbling, discharge, decreased caliber or force • Anal discomfort or rectal bleeding • Sexual dysfunction
When can’t a DRE be done? • Anal fissures---very painful • Anal fistula--very painful • Spasticity of the sphincter • Rectal prolapse
Important issues related to this exam: • Patient modesty • Patient culture • Dr/Pt boundary issues • Patient history of abuse, rape, incest, etc.
What should we do? • Take a complete history • Always have another individual in the room if you do this exam • Talk to patient about their comfort level with this exam, & with you doing this exam • If you or patient is uncomfortable refer to another health professional for this exam!
But, in the end… • Make sure that every patient over 50 (or over 40 with risk factors) is having this exam done annually by SOMEONE! • If you don’t, you are liable for missed diagnoses. (Failure to diagnose is one of the most common successful malpractice claims against DCs.) • Use your education to protect your patients’ health! Be a DOCTOR of Chiropractic.
The Rectum • The rectum is approximately 12 cm long. • Proximally, it joins the sigmoid colon. • Distally, it joins the anal canal at the anorectal junction (about 2.5 to 4 cm). • The distal end is not palpable. • Folds in rectal walls may be palpable.
The Rectum Inferior rectal valve Internal h. plexus Crypts Columns Internal sphincter External sphincter
Sphincter Control • The internal sphincter is made of smooth muscle and is under involuntary autonomic control. • The external sphincter is made of striated muscle and is under voluntary control.
The urge to defecate occurs when the rectum fills with feces which causes reflex stimulation of the internal sphincter. • Defecation is then controlled by the striated external sphincter.
The lower half of the anal canal is supplied with somatic sensory nerves, which makes it sensitive to painful stimuli. • The upper half of the anal canal is under autonomic control and is not well-supplied by sensory nerves. Therefore, it is relatively insensitive to pain (lesions).
The Prostate • Located at the base of the bladder • Surrounds the urethra • Made of both fibromuscular and glandular tissue • How big? • Chestnut size: 4cm X 3cm X 2cm • In infants and children—small and inactive • In adolescents—enlarges and becomes active • After age 25—continues to enlarge
The Prostate Urethra Median lobe Ejaculatory duct
So, what does it do? • It is the source of much investigation. • We know that it contributes to the ejaculatory fluid. • Believed to secrete enzymes that decrease the viscosity of the ejaculatory fluid • Believed to lower acidity of the vaginal canal
Access to the prostate • The posterior surface of the prostate (what we palpate) is in close contact with the anterior rectal wall. • A sulcus runs through the middle of the prostate and divides it into right and left lobes.
So, how do we evaluate the prostate? • Size • Contour • Consistency • Mobility • Protrusion into the rectum • Grade 1, Grade 2, Grade 3, Grade 4 • Sulcus present • Pain with palpation
What does it feel like? • Pencil eraser • Tip of your nose • Thenar pad
Prostate Conditions • Benign prostatic hypertrophy • Prostate carcinoma • Acute prostatitis • Chronic prostatitis • Others: Prostatic calculi or abscesses
Benign Prostatic Hypertrophy (BPH) • Etiology is unknown • VERY common in males over age 50 • Symptoms rare before 40 • 50% have symptoms after age 60 • 70 to 90% have symptoms after age 70
What happens? • The normal tissue is replaced by collagen. • Results in expansion of the capsule, leading to pressure on the urethra; bladder and urinary symptoms (as discussed earlier). • All or part of prostate may enlarge.
Digital Exam of BPH • Size—enlarged • Consistency: boggy, squishy, smooth • Mobility—remains fairly mobile • Protrusion—Grade depends on stage • Sulcus—may be obscured (vs. obliterated) • Should be nontender
The degree of enlargement of the prostate may not be related to symptoms • i.e., a prostate that is markedly enlarged may not obstruct urinary flow
“Acute urinary retention” may occur, and in general symptoms may be aggravated by: • Exposure to cold • Immobilization • Attempts to retain urine • Anesthetics, anticholinergics • Ingestion of alcohol
Other complications: • Incomplete bladder emptying leads to: • Urinary stasis • Predisposes to infection of bladder and tract • Hydronephrosis • Renal calculus formation
Treatments for BPH • “Wait and see” • Drug therapy • Herbal remedies • Prostatectomy
Prostatic Carcinoma • 2nd leading cause of cancer death in males over 65 • An adenocarcinoma (sarcoma is rare) • Rare before the age of 50 • 122,000 new cases/year in the US • Etiology is unknown
Age?? Race?? History?? Diet?? Age over 50 years African-American Family history of CA High in animal fat Risk Factors
Signs and Symptoms • In the early stages, asymptomatic!! • Late in its course: • Bladder obstruction • Ureteral obstruction • Hematuria • Pyuria
Does it metastasize? • Carcinoma from the prostate is responsible for 60% of all skeletal metastasis • 25% is due to lung cancer • Predominantly blastic mets, but may be mixed
So, how do we detect it? • The DRE! • Size— • Contour— • Consistency— • Mobility— • Protrusion— • Sulcus— • Tenderness–
Size—Normal early, enlarged later • Contour—Asymmetrical • Consistency—Hard nodules* • Mobility—May resist movement • Protrusion—Grade 1-4 • Sulcus—Obliterated (advanced CA) • Pain—NO- usually asymptomatic
Important Differentials • Prostatic CA is not the only lesion with hard nodules: • Prostatic calculi • Prostatic TB • Prostate granulomata
But, all hard nodules in the prostate should be considered cancerous, until everything else is ruled out!
PSA • Prostate Specific Antigen • A glycoprotein specific to the prostate, but not to prostate carcinoma • Produced by both healthy and unhealthy prostate tissue • Serum PSA is moderately elevated in 30 to 50% of patients with BPH
PSA Levels* • Levels < 4 ng/ml are considered normal • 4 to 10 ng/ml are considered borderline • Above 10 ng/ml is considered high
The higher the PSA level, the more likely the presence of prostate CA…. • However……. • Men with prostate CA can have negative or borderline PSA levels
How do we prove otherwise? • PSA—is elevated in 25 to 92% of patients with prostate cancer • TRUS-Trans-rectal ultrasound • Biopsy
Borderline PSA levels • PSA density (PSAD): divide the PSA number by the prostate volume (TRUS) • Age-specific ranges: Older men have higher PSA levels, even without CA • PSA velocity: Serial testing that measures how quickly PSA levels rise over time • Free PSA ratio: Bound vs. Unbound • *low levels of free PSA are more likely CA
TRUS • Performed when the PSA level is borderline and the DRE is negative • Visualizes the areas needed for biopsy • Helps determine the prostate volume (PSAD)
