Pathophysiological consequences of obstructive jaundice and perioperative management

摘要

Background: Obstructive jaundice is a common problem in daily clinical practice. Understanding com-pletely the pathophysiological changes in obstructive jaundice remains a challenge for planning current and future management. Data sources: A PubMed was searched for relevant articles published up to August 2016.The effect of ob-structive jaundice on proinflammatory cytokines, coagulation status, hemodynamics and organ functions were evaluated. Results: The effects of obstructive jaundice included biliary tree, the hepatic cell and liver function as well as systemic complications.The lack of bile in the gut,the disruption of the intestinal mucosal barrier, the increased absorption of endotoxin and the subsequent endotoxemia cause proinflammatory cytokine production (TNF-α, IL-6). Bilirubin induces systemic inflammatory response syndrome which may lead to multiple organ dysfunction syndrome. The principal clinical manifestations include hemodynamic in-stability and acute renal failure, cardiovascular suppression, immune compromise, coagulation disorders, nutritional impairment, and wound healing defect. The proper management includes full replacement of water and electrolyte deficiency, prophylactic antibiotics, lactulose, vitamin K and fresh frozen plasma, albumin and dopamine. The preoperative biliary drainage has not been indicated in overall, but only in a few selected cases. Conclusion: The perioperative management is an essential measure in improving the outcome after the appropriate surgical operation in jaundiced patients especially those with malignancy.
