Evaluating the patient with faecal incontinence M62 Course 2004 Mr E S Kiff
Diagnosis HISTORY EXAMINATION INVESTIGATION
History LISTEN to what is being said LISTEN to the problem LISTEN to the effect on their life
The specific questions Urgency Consistency Frequency Defaecation Prolapse Wiping Leakage
Urgency Diarrhoea Weak voluntary muscle Quantify – how long have you got - incontinent en route?
Consistency Solid, formed Soft, loose Watery Variable Explosive
Frequency Diarrhoea – think upstream Formed – think irritability, sensory
Can you go? Connective tissue weakness – prolapse Long term strainer End stage neuropathy
Prolapse Grape - mucosal, think eversion of anus Tomato – full thickness rectal Vaginal – rectum,bladder,uterus,small bowel
Difficulty wiping clean Prolapse Low anal tone Slow to regain tone
Leakage during the day Low resting tone Prolapse
Causes of incontinence Brain Body Bowel Bottom
Brain and cord CVA – IAS weakness? Emotion, anxiety Cord injury MS Peripheral neuropathy Think bladder, think legs
Body Mobility Elderly Exposure of minor weakness
Bowel Inflammatory bowel disease Neoplasia Coeliac Drugs OVERFLOW
Bottom Connective tissue Muscle – neuropathy, tear or BOTH Combination Congenital
Examination Abdomen Perineum Anal canal and pelvic floor Sigmoidoscopy
Examination of the anus Position Gape Strain Length and angle Muscle bulk Connective tissue Voluntary contraction
Investigations The colon Anorectal physiology Endoanal ultrasound Defecating proctography MR scan
Anorectal physiology Anal manometry Vector-volume analysis Rectal perception of distension Proctometrogram Recto-anal reflex PNTML EMG Other tests
Endo-anal ultrasound Beware over reporting Tears found later in life = neuropathy Tears are not all or nothing
Summary Listen to the story Ask the questions Examine the bottom Do the tests Fit the jigsaw together Consider the alternatives for treatment
