    Postoperative endotoxemia (endotoxin in the blood) is elevated in patients with liver cirrhosis or obstructive jaundice, increasing complication risks. This suggests a link between high endotoxin levels and multiple organ failure in these patients.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Critical Care Medicine

    Background:

    • Endotoxemia, or endotoxin in the blood, is a significant concern in surgical patients.
    • Digestive diseases, particularly liver cirrhosis and obstructive jaundice, may predispose patients to higher endotoxin levels.
    • The relationship between postoperative endotoxemia and subsequent complications requires further investigation.

    Purpose of the Study:

    • To investigate postoperative blood endotoxin levels in patients with digestive diseases.
    • To identify complications associated with endotoxemia in these patient groups.
    • To explore the potential link between endotoxemia and multiple organ failure (MOF).

    Main Methods:

    • Blood samples were collected from patients undergoing surgery.

  • Endotoxin levels were measured postoperatively.
  • Patients were categorized based on the presence or absence of liver cirrhosis and obstructive jaundice.
  • Complications such as anastomotic leakage, gastrointestinal bleeding, disseminated intravascular coagulation (DIC), and hepatic failure were recorded.

    • Main Results:

    • Patients without liver cirrhosis or obstructive jaundice showed minimal endotoxin elevation (6.1 pg/ml) and few complications.
    • Patients with liver cirrhosis exhibited significant and persistent endotoxemia, especially after splenectomy (151.0 pg/ml) and hepatectomy (101.3 pg/ml), with one death from hepatic failure.
    • Patients with obstructive jaundice developed endotoxemia (21.6 pg/ml), with complications including gastrointestinal bleeding and DIC.

    Conclusions:

    • Markedly high and persistent postoperative endotoxin levels are observed in patients with liver cirrhosis and obstructive jaundice.
    • These elevated endotoxin levels may be associated with increased risks of complications, including gastrointestinal bleeding, DIC, and potentially multiple organ failure (MOF).
    • Further research is warranted to elucidate the precise mechanisms and clinical implications of endotoxemia in these surgical populations.
