[Endotoxemia after surgery in digestive diseases]

The blood level of endotoxin after operations in patients with digestive diseases, mainly liver cirrhosis and obstructive jaundice, and the complications most likely related to the presence of endotoxemia were investigated. Twenty-seven patients without either liver cirrhosis or obstructive jaundice showed a minimal elevation of the endotoxin level in blood, as shown by 6.1 +/- 3.9 pg/ml at the first postoperative day and there was only one anastomotic leakage. On the other hand, 18 patients with liver cirrhosis showed a notable and persistent endotoxemia after surgery. The cirrhotic patients who especially underwent splenectomy and hepatectomy showed marked elevations of endotoxin level at the first postoperative day, with values of 151.0 +/- 46.1 pg/ml and 101.3 +/- 36.2 pg/ml, respectively, and one of these patients died of hepatic failure. Thirteen patients with obstructive jaundice developed endotoxemia evidenced by the value of 21.6 +/- 4.8 pg/ml at the first day after surgery. Among these patients, two had gastrointestinal bleeding and one developed DIC. The markedly high and persistent levels of endotoxin in patients with liver cirrhosis or obstructive jaundice may be possibly related with the development of MOF.
