ABSTRACT
BACKGROUND: Endotoxaemia due to intraluminal bile salt depletion may be a cause of renal failure in patients with obstructive jaundice. Administration of bile salts to these patients has been reported to decrease portal and systemic endotoxaemia during surgery and improve renal function. However, such changes have not been shown with bile refeeding. We compared the effect of preoperative bile salt administration with preoperative bile refeeding on renal function in patients with obstructive jaundice. METHODS: Sixteen patients with obstructive jaundice underwent percutaneous transhepatic biliary drainage--eight received oral bile salts (500 mg of sodium deoxycholate 8-hourly for 48 hours preoperatively) and the other 8 were refed the total bile output for the entire period of biliary drainage (median 13 days). Blood endotoxin levels and renal function were assessed before, during and after the operation. RESULTS: The number of patients with intraoperative portal and postoperative systemic endotoxaemia decreased after both forms of therapy. Renal function also improved in both the groups--all 4 patients with renal failure recovered. There was a significant increase in creatinine clearance postoperatively after bile salt therapy (from 65 ml/minute preoperatively to 87 ml/minute postoperatively). CONCLUSION: Refeeding of bile obtained by percutaneous catheter drainage is an effective, cost-free substitute for oral bile salts in patients with obstructive jaundice.
