colo rectal cancer referrak
NICE updated their referral guidelines in 2015. The following patients should be referred urgently (i.e. within 2 weeks) to colorectal services for investigation:
patients >= 40 years with unexplained weight loss AND abdominal pain
patients >= 50 years with unexplained rectal bleeding
patients >= 60 years with iron deficiency anaemia OR change in bowel habit
tests show occult blood in their faeces (see below)
An urgent referral (within 2 weeks) should be ‘considered’ if:
there is a rectal or abdominal mass
there is an unexplained anal mass or anal ulceration
patients < 50 years with rectal bleeding AND any of the following unexplained symptoms/findings:
abdominal pain
change in bowel habit
weight loss
iron deficiency anaemia
what is a fit test
every 2 years to those 60- 74
everyone sent a post and antibodies against hb are checked to see amount of human blood in stool
can also be used in
patients >= 50 years with unexplained abdominal pain OR weight loss
patients < 60 years with changes in their bowel habit OR iron deficiency anaemia
patients >= 60 years who have anaemia even in the absence of iron deficiency
what is the dukes classification for colorectal cancer
DUKE ABCD
A- confined to mucosa
B- spread to bowel
C- lymph note metastases
D- distant metastases
what are haemorroids
enlarged vascular anal cushions
painless rectal bleeding is the most common symptom
pruritus
pain: usually not significant unless piles are thrombosed
soiling may occur with third or forth degree piles
external vs internal haemorroid
External
originate below the dentate line
prone to thrombosis, may be painful
Internal
originate above the dentate line
do not generally cause pain
soften stools: increase dietary fibre and fluid intake
topical local anaesthetics and steroids may be used to help symptoms
outpatient treatments: rubber band ligation is superior to injection sclerotherapy
surgery is reserved for large symptomatic haemorrhoids which do not respond to outpatient treatments
management of thrombosed haemorroids
typically present with significant pain
examination reveals a purplish, oedematous, tender subcutaneous perianal mass
if patient presents within 72 hours then referral should be considered for excision. Otherwise patients can usually be managed with stool softeners, ice packs and analgesia. Symptoms usually settle within 10 days
what is a large bowel obstruction
In large bowel obstruction, the passage of food, fluids and gas, through the large intestines becomes blocked.
caused by tumour, volvulus and diverticular disease
