Endoscopic drainage aborts endotoxaemia in acute cholangitis.
Forty patients with acute calculous cholangitis had successful endoscopic drainage. Bile from nasobiliary drains and venous blood was collected at 0, 12, 24, 36 and 48 h after endoscopy. Endotoxin levels were measured by the chromogenic Limulus Amoebocyte Lysate assay. There was a significant reduction in both bile and serum endotoxin levels after endoscopic drainage (P < 0.001). Endotoxaemia occurred when bile endotoxin reached 10(3) EU/ml and rose exponentially beyond this threshold. Significant association was demonstrated between both bile and serum endotoxins to the clinical features of cholangitis (P < 0.05). No correlation was evident between serum endotoxin and the parameters of white cell count, serum bilirubin and alkaline phosphatase (r = 0.53, 0.00 and 0.00 respectively). Endoscopic drainage is effective in lowering bile and serum endotoxin levels and clinical signs and symptoms reliably predict endotoxaemia.
