ETIOPATHOGENESIS OF NON VARICEAL BLEEDING

Peptic Ulcer Disease

• Most frequent cause of upper GI Bleed (40% of all cases)

Duodenal Ulcer-gastroduodenal A.

PUD Gastric ulcer-left gastric A.

Ulcer

Decreased mucosalprotectionNSAID’sSteroidsHypersecretion of acidH.pylori (75% of gastric

ulcers caused by this)Smoking and Alcohol

correlationGastrin (Zollinger-Ellison)

Modified Johnson classification for gastric ulcer

Mallory-Weiss Tears• Mallory-Weiss syndrome refers to bleeding from tears (a Mallory-Weiss

tear) in the mucosa at the junction of the stomach and esophagus, usually caused by severe retching, coughing, or vomiting.

• Mallory-Weiss tears account for 5% to 10% of cases of upper GI bleeding.

Mechanism Forceful contraction of the abdominal wall against an

unrelaxed cardia, resulting in mucosal laceration of the proximal cardia as a result of the increase in intragastric pressure.

Causes

ALCOHOLISM

HIATUS HERNIA

Sress gastritis

• Appearance of multiple superficial erosions of the entire stomach, most commonly in the body

Stress Gastritis

NSAID users

Sepsis

Respiratory failure

Hemodynamic instability

Head injuries with I.C.T (Cushing ulcer)

Burn injuries (Curling ulcer)

Multiple trauma

Oesophagitis

Osophagitis (or esophagitis) is inflammation of the esophagus.

Causes

GERD Inflammation c/c Blood lossInfectious agents in immunocompromised

hosts.

Other causes

CROHN’S DISEASE

Dieulafoy’s Lesion

• Vascular malformations along the lesser curve of the stomach within 6 cm of the GEJ

• represent rupture of unusually large vessels (1-3 mm) in the gastric submucosa.

• Erosion of the gastric mucosa overlying these vessels leads to hemorrhage.

Gastric Antral Vascular Ectasia

• “watermelon stomach”

• collection of dilated venules appearing as linear red streaks converging on the antrum in longitudinal fashion, giving it the appearance of a watermelon.

Malignancy

• usually associated with chronic anemia or hemoccult-positive stool

• Occasionally, malignancies present as ulcerative lesions that bleed persistently.

• most characteristic of the GIST

• Also occur with leiomyomas and lymphomas.

Aortoenteric fistula

abdominal aortic aneurysm repair

pseudoaneurysm at the proximal anastomotic suture line

Infection

fistulization into the overlying duodenum

“sentinel bleed”

Haemobilia

• typically associated with trauma, recent instrumentation of the biliary tree, or hepatic neoplasms.

• suspected in anyone who presents with hemorrhage, right upper quadrant pain, and jaundice

Haemosuccus pancreaticus• bleeding from the

pancreatic duct. • typically caused by

erosion of a pancreatic pseudocyst into the splenic artery.

• presents with abdominal pain and hematochezia

• past history of pancreatitis

Iatrogenic Bleeding

• may follow therapeutic or diagnostic procedures

• common causes of iatrogenic bleeding – endoscopic sphincterotomypercutaneous transhepatic procedures

• 2% of cases• It is often mild and self-limited

The Key

Early identification and surgery for patients in who other lines of management are likely

to fail.

Absolute Indications• Hemodynamic instability despite vigorous resuscitation (>6

units transfusion)

• Failure of endoscopic techniques to arrest hemorrhage

• Recurrent hemorrhage after initial stabilization (with up to two attempts at obtaining endoscopic hemostasis)

• Hemostasis• Anterior ulcer

– 4 quadrant suture-ligation

• Posterior ulcer– suture ligature of the vessel proximal and distal to the ulcer

• An elevation of pulse rate more than 20 or a fall in BP more than 10mmHg indicates atleast a 20% blood volume loss.
