Preoperative biliary drainage (stenting) for treatment of obstructive jaundice.
The role of preoperative biliary drainage in malignant obstructive jaundice has been controversial. Laboratory studies suggest that relief of jaundice prior to major pancreatic resection would be associated with improved morbidity and mortality. However, clinical experience has not supported the laboratory results. Obstructive jaundice can be relieved preoperatively via an endoprosthesis introduced either percutaneously or endoscopically. Cohort studies have not shown any clinical benefit and in some the endoprostheses have been implicated in postoperative complications. The only randomized study has shown no benefit in preoperative drainage, but one recent study has confirmed that endoscopic drainage, whilst not conferring an advantage, did no harm. Hence, whilst preoperative drainage is not recommended, if for any reason operation needs to be delayed, endoscopic drainage via an endoprosthesis can be used without fear of adversely influencing the outcome.
