Adverse effects of biliary obstruction: implications for treatment of patients with obstructive jaundice.

The development of hypotensive complications, renal failure, and cholangitis in patients with jaundice [1-4] has particular implications for radiologists asked to perform diagnostic studies that require IV contrast material and for radiologists, gastroenterologists, and surgeons who do invasive procedures to relieve bile duct obstruction. Although systemic effects of obstruction eventually are eliminated by reestablishment of the free flow of bile, all invasive procedures are painful, require sedation or anesthesia, and can induce fluid shifts, electrolyte abnormalities, hemorrhage, bile peritonitis, and sepsis. A patient with jaundice is less able to respond to and easily decompensates after such stresses [4]. An awareness of the pathophysiologic effects of biliary obstruction is essential because proper preparation of patients with jaundice before invasive diagnostic and therapeutic procedures avoids complications and decreases morbidity and mortality [5-8]. An overview of the systemic effects of bile duct obstruction and their implications for patients who require invasive diagnostic and therapeutic procedures is provided in this article.
