Upper Gastrointestinal Bleeding Epidemiology Duodenal / gastric ulcers: bleeding stops spontaneously in 80% (same in lower GI bleeding); risk of rebleeding if atherosclerosis, posterior wall duodenal ulcer, high lesser curve gastric ulcer, vessel visible in base; 5-6% mortality; 60% GI bleeds are associated with peptic ulcer disease; most common cause of upper GI bleeding Oesophageal varices: bleeding stops spontaneously in 20-30%; present in 20% with cirrhosis; grow by 7%/yrea; 10-15% haemorrhage/year; 60% 1 year bleeding recurrence rate; recurrence rate 20-30%; will usually rebleed unless portal HTN corrected; 15-20% 6/52 mortality per bleed; 25-40% overall mortality; most common cause of re-bleed in upper GI bleeding Aetiology Peptic ulcer disease, ETOH, NSAIDs (2x risk of upper GI bleed), ARDS, burns, CNS disease, cancer, smoking, aorto-enteric fistula; due to gastritis / oesophagitis / duodenitis in 13% Pathophysiology Examination helps determine site of bleeding in 40%; look for signs of chronic liver disease / coagulopathy Bleeding sites: 25% duodenal ulcer / 25% gastric erosion / 20% gastric ulcer / 20% Mallory Weiss tear / 7-10% oesophageal varices Peptic ulcer disease 60%; Gastritis / oesophagitis / duodenitis = 13% Haematemesis: Bleeding proximal to ligament of Treitz; occurs in 50-66% patients with upper GI bleeding; bright red = severe Melaena: From upper GI / proximal colon; more liquid = more severe; haematochezia – 10-14% is upper GI Mallory-Weiss tear: small tear in mucosa of upper cardia of stomach – in gastro-oesophageal junction; due to violent vomiting (prior history of vomiting in 50%) mild haematemesis; brighter blood Investigation FOB: false +ive due to raw meat, horseradish; false negative due to vitamin C; remain positive for 2/52 after significant GI bleed Bloods: Ur:Cr >200 (40% sensitivity, 95% specificity, LR+ 6.4; due to breakdown of Hb protein) ECG: if shock / anaemia / PMH of IHD Erect CXR: if significant pain, suspect pulmonary pathology, ?oesophageal rupture NGT: if unclear history; sensitivity 60%, specificity 75%; presence of fresh blood on aspiration has mortality compared to clear Angiography: can detect bleeding if >0.5ml/min; may be helpful if bleeding / large clots make endoscopy hard C: IV fluids, clotting factor replacement, reversal of anticoagulation, platelets if needed, IDC, inotropes Blood transfusion if: >2L N saline resus; initial Hb <8; significant risk of rebleeding; co-morbidities ability to tolerate anaemia D: treat hepatic encephalopathy Admit ICU if: variceal bleeding, CV instability, significant co-morbidities, endoscopy features of recent Haemorrhage Management If peptic ulcer disease: No drugs have been found to be of benefit if acute bleeding is from duodenal ulcer High dose PPI: 80mg IV omeprazole 8mg/hour INF to maintain gastric pH >6 Pros: Reduces hospital LOS / active bleeding time at endscopy / need for OT Cons: No effect on transfusion requirement, recurrent bleeding, mortality Gastroscopy: treatment of choice; identifies source of bleeding in 90%; perform within 12-24 hours if stable, immediately if unstable; can do injection therapy, thermal devices, laser therapy Pros: rebleeding by 60% / mortality by 45% / emergent OT by 65% Indications for urgent scope: active / recurrent bleeding, bright red blood in vomit, large bleed (>2iu RBC needed), variceal bleeding Early discharge after if: non-bleeding Mallory-Weiss tear, clean-based ulcer OT: emergent OT required in 6-8% Indications for OT: active bleeding not controlled on endoscopy, recurrent bleeding, perforation, failure of conservative management, blood transfusion >5iu, refractory shock Outpatient management: suitable for discharge without scope if: <60yrs, <200ml blood loss, no cardiovascular compromise, no melaena, normal coagulation, no bleeding with 4 hours observation. Organise outpatient scope. Management (cntd) If variceal bleeding: Octreotide: somatostatin analogue splanchnic vasoconstriction; give 50-100mcg (1mcg/kg) bolus 2550mcg/hr (1-4mcg/kg/hr) for 48 hours; as effective as immediate sclerotherapy (in 75-90%); monitor BSL as causes glu; alternative is vasopressin Pros: Reduces active bleeding / transfusion requirement by 1/3 Terlipressin: vasopressin analogue; 2mg Q6h for 1st day 1mg Q6h Cons: increases afterload so may cause CO if poor LV function; risk of MI, HTN, peripheral ischaemia Sengstaken-Blakemore / Minnesota tube: control bleeding in 70-90% (50% recurrence rate on removal however); use only if emergency endoscopy not available as high risk of complications; insert gastric balloon 1st with 50ml air Xray to confirm intragastric further inflate to 250ml traction if still bleeding, inflate oesophageal balloon to max 40mmHg; use for max 48-72 hours Indicated if: severe variceal bleeding uncontrolled by other measures (sclerotherapy and vasopressin), >2L transfusion requirement in 24 hours, Mallory-Weiss tear with ongoing bleeding Complications: in 25-30%; pulmonary aspiration in 10%; oesophageal perforation; sinusitis; mucosal ulceration; necrosis of alar cartilage; tracheal compression Nadolol + ISMN: reduces portal venous p Banding / sclerotherapy: obliterates bleeding varices in 80-90% Sclerotherapy: 40% complication rate (eg. Perforation, aspiration, pyrexia, chest pain, ulcers, strictures) Ligation: as effective as sclerotherapy, with less side effects Transjugular intrahepatic portal-systemic shunt (TIPS): use if continued bleeding despite ligation; controls bleeding in 90%; lower mortality and morbidity than portocaval shunt; 1yr mortality by 25% / risk of rebleeding by 50% if associated with severe cirrhosis Contra-indications: encephalopathy, pre-terminal liver failure, portal venous thrombosis, intrahepatic sepsis, significant cardiac disease Angiography: if not controlled by endoscopy; embolisation stops bleeding in 80% OT: partial gastrectomy; oesophageal transection; if failure of endoscopy / failure to visualise / massive RBC transfusion (>6-8iu/day or >12iu at any time) Prognosis Mortality 6-11% (usually due to multi-organ failure and co-morbidities, rather than exsanguination) Glasgow Blatchford score: <4% need transfusion / need OT / die if: Ur <6.5, Hb >130 (120 in women), SBP >110, HR <100, no syncope / liver disease / CCF PUD: Clean base ulcer = 5% risk rebleed, 2% mortality Active bleeding ulcer = 55% risk rebleed, 11% mortality Poor prognosis: Hct <30%, SBP <100, red blood in NG/vomit, PMH cirrhosis, ascites Poor prognostic signs in varices: active bleeding at scope; >2L transfusion requirement; encephalopathy; abnormal LFT’s Paediatrics <2/12: swallowed maternal blood (do Apt test to tell fetal from maternal blood, fetal blood stays pink, maternal goes brown), stress ulcer, AV malformation, haemorrhagic disease of newborn, coagulopathy 2/12-2yr: gastro / oesophagitis / stress ulcer, toxic ingestion / foreign body, Mallory-Weiss tear, AV malformation >2yr: gastro / gastritis / PUD, toxic ingestion / FB, Mallory-Weiss tear, AV malformation, varices (due to biliary atresia, cystic fibrosis, hepatitis, alpha-1 antitrypsin deficiency), haematopbilia Nasogastric lavage determines site of bleeding and rate
