WHAT ARE ABDOMINAL CATASTROPHIES?

CATASTROPHIC EMERGENCIES

HAEMORRHAGE SEPSIS

HAEMORRAHGE

Upper GI Small Bowel Colorectal Solid organ

Massive UGI Bleed

Gastric or duodenal ulcer Varices Mallory-Weiss tear Oesophageal ulcer

Oesophageal Bleeding

Varices Mallory-Weiss tear Esophagitis/ulcer – acid reflux, infection Neoplasia Trauma

Gastric Bleeding

Gastritis Superficial Stress ulceration Mechanical

Gastric Bleeding

Gastric Ulcer Benign or malignant

(10%) Initial biopsy if safe Repeat OGD to assess

healing & repeat bx Benign: drug-induced,

hypersecretors +/- H. pylori infection

Duodenal Bleeding

Duodenitis Benign ulcer Crohn’s Neoplasia Vascular Malformation Dieulafoy

Duodenal Bleeding

Haemobilia Aortoduodenal fistula

Duodenal Bleeding

Benign ulcer May have all the

same etiology as stomach

Major bleeding usually gastroduodenal artery

SB Haemorrhage accounts for 2-3% of GI bleeds

Jejunal diverticulosis

Meckel’s Diverticulum

CLINICAL SCENARIO MASSIVE UGI BLEED

32 year old male found at home in a pool of blood & still vomiting blood

VGH ER pulse140 BP 60/0 Hb 32 Massive resuscitation/transfusion protocol Codes x 2 in ER OGD bleeding ++++

UGI BLEED

OR STAT laparotomy Codes shortly after laparotomy Duodenotomy/gastrotomy Watermelon stomach torrential

haemorrhage Blood gushing from duodenum Died on table

Colon Bleeding

Angiodysplasia Diverticular disease Neoplasia: Adenocarcinoma, GIST’s Ischemia Hemmorhoids IBD Infection: Campylobacter, Shigella,

Salmonella, Enteropathogenic E. coli

LGI Bleed

Acute bleeding occurs in 20-30 cases/100,000 annually

20-30% of GI bleeds

Angiodysplasia

Diverticulosis

Barium enema - diverticulosis

Lower gi bleed red cell scan
