ETIOPATHOGENESIS OF NON VARICEAL BLEEDING
Atul JG
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
decrease splanchnic
mucosal blood flow
altered gastric luminal acidity
Seen in…
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)

Priorities
•Control Hemorrhage !!• Definitive procedure for the underlying pathology
Duodenal Ulcers
• Exposure of bleeding site– Longitudinal duodenostomy– Pyloroduodenostomy
• Hemostasis• Anterior ulcer
– 4 quadrant suture-ligation
• Posterior ulcer– suture ligature of the vessel proximal and distal to the ulcer
