Assessment – the evidence • No evidence-based assessment protocols • Informed opinion: history and physical examination most important • Clinicians often fail to examine • Physical environment and carers may be most important factor for immobile people
What tests are needed? • Comprehensive history (Norton & Chelvanayagam, 2000) • Diary & symptom questionnaire • Physical examination • If bowel investigation needed: colonoscopy • Anorectal physiology tests? • Anal ultrasound? • If indicated: proctogram, bloods
What goes wrong? • Anal sphincter (childbirth, injury, iatrogenic damage, degeneration) Internal anal sphincter - passive soiling External anal sphincter - urge incontinence • Gut motility (infection, inflammation, radiation, hypermotility, emotions) • Stool consistency (diet, motility, anxiety) • Local pathology (prolapse, piles, fistula) • Neurological damage (motor or sensory) • Lifestyle, toilets, drugs,immobility…
History • Pre-morbid and current bowel symptoms • Timing of onset, is it worsening? • Faecal incontinence: • Urgency = loose stool or EAS problems • Passive loss = IAS problems or incomplete evacuation • Constipation: • Slow transit or evacuation difficulty (or both)?
History • Co-morbidities and general health • Diet (amount, type and pattern) • Fluids (amount, type and pattern) • Toileting abilities, mobility, carers and toilet facilities • Medications • Lifestyle & psychosocial support • Depression and anxiety
Stool form can give clues as to pathology • Loose stool more difficult to control • Hard stool suggests evacuation difficulty • Must ask about bleeding (bowel cancer second commonest cancer in UK) - refer to rectal bleeding clinic • Do not assume bleeding is piles
One week diary gives a baseline Tick in shaded column when open bowels in toilet Tick in white column for incontinence or pad change More complex diaries may be needed for special groups
Physical examination • Abdomen (masses, bladder) • Anal inspection (soiling, prolapse, scarring, haemorrhoids, gaping) • Digital anal (resting tone and squeeze) • Digital rectal (loading, masses) • Examine for prolapse on toilet • Vaginal (rectocele)
Observing the perianal area • Rectal or vaginal prolapse • Haemorrhoids or skin tags • Wounds, lesions, discharge • Gaping anus • Skin condition • Bleeding • Stool, infestation and foreign bodies
