no
vomitting large amounts of blood with chronic hep B. Dx?
oesophageal varices
pathophysiology of oesophageal varices due to hep B
hep B –> fibrosis –> cirrhosis –> backflow pressure on portal vein –> portal HTN –> varices –> rupture –> +++ bleeding due to high pressure
2 biggest causes of varices
viral hep
alcoholic hep

adenocarcinoma
contrast shared Sx of bowel cancer vs malignant bowel cancer sx only
shared = tenesmus, bleeding, change in bowel habit
malignant = weight loss, fever, night sweats, reduced appetite, bowel obstruction
staging method for bowel cancer
TNM
t = depth of invasion
n = nodes
m = mets
tx options for colorectal ca

radio - only if tumour left after surgery
which colorectcal cancer is primarily treated by radio
rectal ca
left lower abdo pain, fever. Prev PC cramping, constipation. Dx?

cause of diverticulosis
low fibre diet –> constipation –> straining –> stretching of weak points in bowel wall
