Rectal Bleeding
Up to 38% of people will experience rectal bleeding at
some point in their lives
Only 13-40% of these will consult a doctor about it
The majority of cases are benign and caused by minor
problems that can be managed in primary care
Causes
Common
Benign anorectal disease:
o
Haemorrhoids
o
Anal fissure
o
Fistula-in-ano
Diverticular disease
Inflammatory bowel disease:
o
Crohn’s disease
o
Ulcerative colitis
Polyps
Malignancy
Rarer
Coagulopathies
Arteriovenous malformation
Massive upper GI bleeding
Radiation proctitis
Ischaemic colitis (mesenteric vascular
insufficiency)
Solitary rectal ulcer syndrome.
Dieulafoy's lesion of small or large
bowel.

Rectal varices
GI tract invasion of non-GI tract
malignancy

History & Examination
Urgent 2ww Referral
All ages
Definite, palpable, right sided, abdominal mass
Definite, palpable, rectal (not pelvic) mass
Unexplained iron deficiency anaemia
AND:
[ ] Male with a Hb of < 110g/l
[ ] Non menstruating female with a Hb of < 100g/l
Over 40 years
Rectal bleeding WITH a change of bowel habit towards looser stools
&/or increased frequency 6 wks (soon to change to 3 wks)
Over 60 years
Rectal bleeding persisting 6wks WITHOUT a change in bowel
habit or anal symptoms (e.g. soreness, discomfort, itching, prolapse,
pain)
Change in bowel habit to looser stools &/or more frequent stools
persisting 6 wks WITHOUT rectal bleeding
(both due to change to age >50yrs with duration >3 weeks)
Routine Referral to Secondary Care
No red flag sx, but other GI symptoms
Abdominal pain
Change in bowel habit
Weight loss
Previous colonic adenomatous polyps or
malignancy
Past history IBD
Strong family history colorectal cancer
1 First Degree Relative (FDRs) <50
2 FDR of any age
Age >55yrs (not meeting 2ww criteria)
These patients may need investigation with
colonoscopy (rather than flexi sig) to exclude other
pathology
Referral for Direct Access Flexible
Sigmoidoscopy (DAFS)
If no other GI symptoms and
aged <55:
Conservative management
Refer for direct access
flexible sigmoidoscopy if:
Symptoms not settling within
4 weeks (or recurring)
High level of patient anxiety
Results of DAFS
174 patients attended so far
Colonic pathology found in 39/174
22%
16 hyperplastic polyps
Significant pathology in 23/174
3 cancers
10 adenomatous polyps
10 new diagnoses of IBD proctitis
13%
DAFS Patient Satisfaction
Procedure done quickly enough:
78% yes, 22% no
Helpful to have test on one visit to hospital:
87% - yes, prefer one visit
4% - no, prefer to see dr in OPD first (9% don’t mind)
Overall satisafaction:
Very satisfied 61%, Satisfied 13%, Neutral 9%,
Dissatisfied 9%, Very dissatisfied 9%

Directly bookable appointment
Appointments available on Tuesday mornings
Complete referral form and send electronically with
CAB
Give patient information leaflet to patient
Information for patients medications
Aspirin & Clopidogrel:
Continue
No contraindication to diagnostic procedure +/- biopsies on aspirin
or clopidogrel
Warfarin:
Continue
GP to check INR 1 week before endoscopy date
If INR within therapeutic range, continue usual daily dose
If INR above therapeutic range but <5, reduce daily dose until INR
returns to therapeutic range
Iron tablets:
Stop 1 week before procedure
Information for patients – the
procedure
Bowel prep
Consent
Procedure
Unsuitable Patients
Acute anal pain suggestive of anal fissure (procedure
unlikely to be tolerated)
Recent MI or CVA within 6w
Obesity (overall weight >135kg)
Dementia
Poor mobility (need to be able to transfer from chair to
bed)
Follow-up
All patients will be discharged back to primary care
following this procedure unless diagnosis of serious
pathology found:
malignancy
IBD
adenomatous polyps
The report will include detailed advice on
management
Anal Fissure
A tear of the squamous lining of the distal anal canal.
Clinical Features:
Sharp searing perianal pain, worse after defaecation.
Bleeding is common, usually bright red on tissue paper.
Pruritus and irritation.
Examination (gently part buttocks) may reveal linear split,
usually in midline posteriorly (90%), or anterior midline
10%. Fissure may not be seen, but may be palpated or be
tender on palpation of the anal margin.
Anal Fissure
Anal Fissure - Management
Acute: <6 weeks - conservative management:
Increase fluid intake
High fibre diet
to achieve soft stools
?Bulk forming laxatives (fybogel)
Topical creams –1w course of lignocaine gel
Sitz baths
Oral Analgesia
pain relief
Anal Fissure - Management
Chronic: >6 weeks
Continue conservative measures
Combination of bulk forming laxative (Fybogel BD) and softening
laxative (Lactulose BD) for the full 8 weeks
Prescribe topical 0.4% Glyceryl Trinitrate (GTN) BD for 8 weeks course
N.B. 40% develop headaches as side effect
2 tubes of 30g should be sufficient to cover the 8 week course.
Cost £34.80 for 30g tube
If fissure fails to heal (after 8 weeks of GTN) or if side-effects on GTN
ointment switch to diltiazem 2% ointment (Anoheal®)
Applied topically BD for 8 weeks.
Cost of Anoheal® is approx £45 per tube
If not settling – refer to secondary care
Internal Haemorrhoids
Abnormally swollen vascular mucosal cushions that
are present in the anal canal originating from above
the dentate line.
first degree
Project into lumen of anal canal but do not prolapse
second degree
Prolapse on straining then reduce spontaneously
third degree
Prolapse on straining but require manual reduction
fourth degree
Prolapsed and incarcerated; cannot be reduced
Internal Haemorrhoids
Internal Haemorrhoids
Clinical Features:
rectal bleeding
mucus discharge
itching and irritation
often painless (unless thrombosed or strangulated)
Causes:
Straining
Increasing age
Raised intra-abdominal pressure
Hereditary factors
Internal Haemorrhoids- Management
Increase oral fluid intake
Dietary advice
Consider laxatives
Bulk forming (ispaghula husk)
Lactulose (osmotic) or docusate (stimulant laxative with stool
softening properties, avoid in pregnancy)
Topical anaesthetics with corticosteroids - use for up to 7 days
Oral analgesics
Referral if:
fail to respond to conservative management
persistent bleeding, severe prolapse, affecting daily living
fourth degree haemorrhoids
Urgent referral if:
thrombosis with severe pain, incarceration, gangrene or sepsis
External Haemorrhoids (Perianal haematoma)
A thrombosis of the external haemorrhoid plexus,
arising from below the dentate line
Clinical Features:
acute severe pain, peaks 48-72hrs after onset
usually self-limiting to 7-10 days
bleeding
discomfort
itch
External Haemorrhoids (Perianal haematoma)
Internal piles: Management
Analgesia
Topical anaesthetics and corticosteroids
Cold compresses
(If pt not tolerating pain in first 72hrs, consider
referral for I&D)
Skin tags
Growths of excess skin in the anal region, which are
often a remnant following the resolution of a
thrombosed external haemorrhoid or other perianal
trauma or inflammation, though they can be an
isolated finding.
Clinical features:
pruritus usually the biggest problem
usually skin-coloured lesions arising from the rim of the
anal canal, which don’t contain dilated blood vessels
Skin tags
Skin tags - Management
Anal hygiene
Wash after defaecation
Thorough attention to anal washing in bath or shower
Avoid perfumed soaps, biological washing powders,
fabric conditioners
Use cotton underwear, avoid tight fitting trousers
Management of constipation
Refer for removal if large and troublesome
