Hepatorrhoea is an excessive flow of bile from the liver — an old, rare medical term for bile pouring out in abnormal volume, whether into the intestine or, after injury or surgery, through a fistula or drain. The liver normally secretes 500–1,000 ml of bile daily, carefully metered to digestion; truly excessive external loss depletes the body of bile salts, impairing fat digestion and absorption of vitamins A, D, E, and K, and draining fluid and electrolytes. Modern medicine seldom uses the word, preferring precise descriptions — biliary fistula, bile leak — and managing them with drainage, stenting, or surgery. It survives as a reminder of medicine’s once-florid Greek-derived vocabulary.
