Thanks to Dr. Kincade for presenting today’s Morning Report!
Esophageal Varices
- Esophageal varices are dilated veins within the wall of the esophagus, usually at the distal end
Epidemiology
-50% of patients with cirrhosis; 25% to 35% variceal rupture within 2 years of diagnosis.
-Greatest risk of rupture in first year
-80% to 90% of bleeding episodes in cirrhotic due to variceal hemorrhage and one-third of deaths in cirrhotic patients can be attributed to variceal hemorrhage
-70% of patients who survive initial bleed experience a recurrence 6 weeks after the initial bleed. Mortality rebleeding is 20% to 30%
-Alcoholic and viral cirrhosis are the predominant causes
Causes
-Portal hypertension is commonly a complication of liver cirrhosis, either alcoholic or viral in origin
-Schistosomiasis (the commonest cause of portal hypertension worldwide)
-Portal vein thrombosis
-Splenic vein thrombosis
Prevention
Primary: ß-blockers with or without isosorbide mononitrate, abstinence from alcohol and hepatotoxic drugs, Endoscopic therapies for primary prevention include endoscopic injection sclerotherapy (EIS) and EBL
Symptoms
Varices, hematemesis can be minor, or massive and life-threatening, melena, dyspnea associated with anemia and/or dizziness (especially on standing) resulting from hypotension
Signs
Alcohol on the breath, signs of chronic liver disease: jaundice; palmar erythema, clubbing, asterixis, and leukonychia; scratch marks due to pruritis, bruising, spider nevi on the torso distended abdomen due to ascites and/or hepatosplenomegaly; and gynecomastia and testicular atrophy in men, warm skin, tachycardia, hypotension, splenomegaly, and dilated veins in the abdominal wall
Work up
-Electrolytes, CBC, LFTs, Coags, Type and Cross
-Endoscopy
Diff Dx
Peptic ulcer, gastritis, gastric carcinoma, budd chiari syndrome, esophagitis, malory weiss syndrome
Tx for acute bleeds
-A,B,C, IV (2 large bore), O2, monitor
-Stat GI consult
-MICU consult
-Non selective B- blockers
-Octreotide
-Antibiotic ppx: decrease rebleeding and improve survival
-EBL
-EIS
-TIPS
