GI Bleed Flashcards
LGIB
Massive bleed rare or DIVERTICULAR disease or ischaemic colitis.
Minor bleeds: haemorrhoids are common
Haemorrhoids Anal fissure Colon cancer Colitis: UC, crohns, infective, ischaemic Angiodysplesia (abn collection of blood vessels) Diverticular d Polyps Meckels diverticulim
Mx
Large: resuscitation-> IV fluids, blood transfusion,
Then site must be determined:
Rectal examination - carcinoma?
Proctoscopy - haemorrhoids? (Rigid sigmoidoscopy)
Sigmoidoscopy (flex) -IBD
Barium enemas for mucosal lesions
Colonoscopy- dx + removal of polyps
Angiography- vascular abnorm- angiodysplesia
Chronic GI bleed
Usually presents w/ Fe deficiency anaemia
Blood loss in all men
Women after menopause
Always result from bleeding from GI tract.
Oesophageal varices, DU and Diverticular D rarely bleed chronically.
Malabsortpion (esp coeliac), prevx gastrectomy+ poor dietary intake –> Fe def anaemia similar to anaemia due to chronic blood loss.
Inv
Top and tail at same endoscopic session- gastroscopy and colonoscopy- distal duodenal biopsy taken to exclude coeliac for anaemia
More if anaemia not responding to Fe tx or visible blood loss
1. Small bowel barium follow-through - help if crohns suspected- lesions
Small bowel enteroscopy and /or wireless capsule endoscopy.
Coeliac axis and mesenteric angiography
Technetium labelled red cell scan.
Mx
Tx + oral FeSO4 for anaemia.
