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

CLINICAL SCENARIO MASSIVE LGI BLEED
