Introduction Bleeding of GIT proximal to ligament of treitz. Ligament of treitz- a fibromuscular band which extends from right crus of diaphragm to duodenojejunal flexure.
Presents as: Haematemesis,, malena, hematochezia or occult blood. Malena can present with loss of 50-60ml of blood. May be acute or chronic 100 cases per 100,000 person per year.
Accounts for 3-5% of all hospitalizations The incidence is 2- fold greater in males but death rate is similar in both sexes. Overall mortality from acute bleeding is 20%. Mortality & morbidity increases as age advances (>60 yrs)
Aetiology (Common causes) 4.Mallory- Weiss syndrome 5% of cases Characterized by longitudinal mucosal tear in the cardioesophageal region. Result from repeated vomitting or retching. Common in male alcoholic patients
B.Acute upper GI bleeding Presents as emergency with hemetemesis or malena. Hypovolaemia: i.Mild: no significant hypovolaemia. ii.Moderate: hypovolaemia which responds to volume replacement. iii.Severe: hypovolaemia with continued active major bleeding making resuscitation difficult even with blood transfusions. These patients are difficult to manage. Patients will show all signs of shock.
Note: all patients should be examined for stigmata of CLD. H/O drugs (NSAIDS). H/O ulcers. H/O alcohol abuse.
Resuscitation Initial management has 4 primary goals: 1.Quick assessment with attention to hemodynamic status 2.Appropriate resuscitation (ABC) & monitoring 3.Identify major source of bleeding 4.Specific therapeutic intervention.
Resuscitation (General measures) Airway cleared of clot. Oxygen inhalation. Maintain IV line with at least 2 wide bore cannulae Sample to blood bank for cross matching. Class I + II hemorrhage replace with crystalloid. Class III + IV hemorrhage replace with crystalloid & blood. Pass NG tube for diagnostic & therapeutic purpose. Catheterize the patient. Sedation may be needed.
Specific measures If stable following resuscitation, proceed for upper GI endoscopy. Endoscopy ideally done within 4-24 hrs. If patient could not be stabilized, an emergency laparatomy may be necessary.
Diagnosis History of: Epigastric pain or retrosternal burning hematemesis, melena, or hematochezia. Vomiting, weight loss, alteration of bowel habits. Aortic graft surgery Use of ASA, NSAID’S, steroids, alcohol addiction
Diagnosis Physical examination Vital signs may show hypotension & tachycardia. Cool, clammy skin. Petechiael hemorrhage & purpura seen in coagulopathy. Signs of chronic liver disease. Proper abdominal & rectal examination.
Endoscopy Most important investigation For diagnosis & intervention Establishes diagnosis in 90% of patients Can be repeated more than once.
Arteriography In pts who bleeds contineously & site can not be identified. Has accuracy of 50-90%. Accuracy is increased if there is active bleeding during investigation. Demonstrates bleeding of 0.5-1.0ml/min With technetium-labelled RBC, 0.1-0.5ml/min Embolisation may be done at same time
Barium swallow / meal Used when endoscopy is not available Double contrast study is ideal May show varices, esophagitis, peptic ulcers, gastric tumors etc
Abdominal Ultrasound scan To assess both liver architecture and portal circulation More widely available than Arteriography Should be performed before more invasive procedures
Lab Investigations CBC Electrolytes Glucose Coagulation studies Liver function studies Blood grouping and cross-match
Lab investigations CBC, urea/creatinine, S/Electrolytes, ABGs. ed urea/ creatinine in upper GI bleeding. Normal Hb in pts with active bleeding. Iron deficiency anemia in chronic blood loss.
Treatment ( peptic ulcer disease) At endoscopy 10ml epinephrine at ulcer base Thermal treatment with bipolar diathermy Laser photocoagulation Rebleed is treated similarly A second rebleed is treated by surgery
Post endoscopy treatment Continuous intravenous infusion of Octretide (somatostatin analogue) Proton pump inhibitors H. pylori treatment may be required.
Surgery - PUD Indications for surgery are: Exsanguinating hemorrhage Visible spurting arterial bleed Concomitant perforation Pts >60 yrs, who rebleed once or need 4 units at resuscitation or 8 units in 48 hrs Younger pts requiring 8 units at initial resuscitation or 12 units in 48 hrs Rare blood group
Treatment Gastric erosions / stress ulcers Treatment of underlying cause Intraluminal antacids IV proton pump inhibitors Bleeding usually subsides in 24-48 hrs
Treatment Esophageal varices 1. Endoscopic sclerotherapy Repeated at 3 weeks interval then 3 monthly until varices disappear Some sclerosing agents are ethanolamine oleate, sodium morrhuate, 3% tetradecyl sulphate, absolute alcohal 2. Rubber band ligation 3. Vasoconstriction therapy (octreotide, vasopressin, propranolol)
4. Balloon tamponade: if above measures fail Modified Sengstaken- Blakemoore tube Minnesota tube, Linton tube, Foley catheter Balloon tamponade applied for 12 hrs Stop bleeding in 80% of cases Must be followed by surgery as bleeding is likely to recur after removal.
Surgery – esophageal varices TIPS: in refractory bleed Shunt established between portal vein & Rt or middle hepatic vein Stapling transection of esophagus at CEJ Distal splenorenal shunt Portosystemic shunts Spleenectomy in hypersplenism Liver transplantation
Conclusion Upper GI bleeding is not uncommon & may be life threatening. Prompt intervention could be life saving. It require multidisciplinary approach. Definitive treatment depends upon the final diagnosis.
