Esophageal varices

Quick action prevents a negative outcome.    

Takeaways:

  • Cirrhosis of the liver causes scaring, shrinking, and hardening.
  • Complications of cirrhosis include portal hypertension, esophageal varices, hepatic encephalopathy, jaundice, renal failure, and splenomegaly.
  • Esophagogastroduodenoscopy is the gold standard for diagnosing and grading esophageal varices.

Darrel,* a 60-year-old man with acute onset of confusion, is admitted to the telemetry unit. His family had found him disheveled and rambling incoherently with dried vomit on his face.

History and assessment

Darrel has been drinking 1 pint of whiskey each day for 35 years. He worked in construction until he was terminated for absenteeism. His family reports that he’s reclusive, depressed, and hasn’t sought medical care for many years.  

During your admission assessment, Darrel’s BP is 180/100 mmHg; HR, 106 beats per minute (bpm); RR, 24 breaths per minute; and temperature, 98.6° F (37° C). An ECG shows sinus tachycardia. Darrel is drowsy but arousable, incoherent, and restless. His sclera and skin are jaundiced, and you observe ascites, asterixis, decreased leg and arm muscle mass, finger clubbing, and rhonchi lung sounds. You detect hepatomegaly when you palpate Darrel’s right upper abdomen. He has an I.V. of 0.9% normal saline running at 75 mL/hr, and he’s on oxygen at 2 L by nasal cannula.  

Lab results include hemoglobin 10 g/dL, platelets 126 × 103/µL, and significantly elevated liver enzymes (ALT and AST). The provider orders telemetry and for vital signs to be checked every 30 minutes. As a precaution, you set up suction in Darrel’s room. 

Over the next 3 hours, Darrel’s HR rises to 154 bpm and his RR increases to 32 breaths per minute. He remains in sinus tachy­cardia, his O2 saturation is 89%, and his BP drops to 100/40 mm Hg. Darrel becomes more restless and agitated. He vomits 75 mL of coffee-colored emesis and his skin is pale. You activate the rapid response team (RRT).  

On the scene 

As the team arrives, Darrel yells out loudly and then vomits copious amounts of bright red blood. His skin is ashen, and he becomes unresponsive. You use a 16-gauge needle to start another I.V. in his right antecubital so you can infuse a wide open normal saline bolus of 250 mL and prepare to administer blood. Darrel begins responding to painful stimuli and is maintaining his airway, but you have an oropharyngeal airway at the bedside in case you need it. You evaluate his vital signs every 5 minutes. 

Blood work shows that Darrel’s hemoglobin has dropped from 10 to 8.5 g/dL, with other values unchanged. Arterial blood gas­es show hy­poxemia with PaO2 72 mmHg and SaO2 82%.  

Darrel is transferred to the ICU, where he continues to bleed, passing large amounts of melena and hematemesis. The provider orders an initial I.V. bolus of octreotide 50 mcg with a continuous I.V. infusion of 50 mcg/hr.

Outcomes 

Darrel is diagnosed with esophageal varices caused by decompensated end-stage liver disease. He undergoes emergent esophageal banding and ultimately recovers. Before discharge, he’s referred to a case manager who helps connect him with an addiction specialist.   

Education 

Cirrhosis of the liver increases portal hypertension, which can lead to esophageal varices—dilated submucosal veins in the esophagus. If left untreated, varices can cause life-threatening bleeding. Treatment includes vasodilator and vasoconstrictor medications, sclerotherapy, and endoscopic ligation with banding. Fluid volume resuscitation should be used to achieve and maintain a hemoglobin of 7 to 8 g/dL; however, aggressive fluid resuscitation may increase the portal pressure and cause rebleeding. To decrease the pressure, a transjugular intrahepatic portosystemic shunt can be used to reroute blood.    

Patients should be referred to addiction specialists and should see a gastroenterologist for continued evaluation.
