Introduction
Hepatic encephalopathy may be initiated by many factors such as gastrointestinal bleeding, infections, fluid and electrolyte disturbances. Hypokalemia is one of the most commonly encountered electrolyte abnormalities causing hepatic encephalopathy in patients with cirrhosis.
Case presentation
We present the case of a 62-year-old Caucasian man with decompensated liver cirrhosis having multiple episodes of hepatic encephalopathy precipitated by vomiting. He had an incisional hernia at the right lumbar region. A barium contrast study of the small intestine and magnetic resonance imaging showed that the hernial sac included gastric antrum and bowel. We observed that hepatic encephalopathy coincided with hypokalemia as a result of a large volume of vomiting triggered by the collapsed hernial sac. Hepatic encephalopathy was resolved by administration of intravenous potassium.
Conclusion
This case illustrates that a hernia causing a large volume of vomiting may be a precipitant factor in the development of hepatic encephalopathy.
