Pneumoperitoneum during laparoscopic surgery can temporarily affect liver function, increasing liver enzymes and affecting clotting time. Higher pressures and longer durations worsen these effects, cautioning against prolonged procedures in patients with severe liver issues.

Area of Science:

  • Hepatology
  • Surgical Anesthesiology
  • Gastroenterology

Background:

  • Limited research exists on pneumoperitoneum's impact on liver function.
  • No established consensus on the physiopathological hepatic implications of pneumoperitoneum.

Purpose of the Study:

  • To evaluate the effects of pneumoperitoneum on hepatic function in patients undergoing laparoscopic procedures.

Main Methods:

  • 52 patients underwent laparoscopic procedures (cholecystectomies or nonhepatobiliary).
  • Liver function tests (AST, ALT, bilirubin, prothrombin time) were monitored post-operatively.
  • Procedures varied in pneumoperitoneum pressure (10 vs. 14 mmHg) and duration.

Main Results:

  • All patients showed temporary post-operative increases in AST, ALT, bilirubin, and prothrombin time.

  • Liver function returned to normal 48-72 hours post-operation.
  • Increased AST and ALT levels correlated significantly with higher pneumoperitoneum pressure and longer procedure duration.

    • Conclusions:

    • Intra-abdominal pressure (level and duration) influences hepatic function changes during laparoscopy.
    • Patients with normal liver function tolerate these changes, but prolonged procedures may pose risks.
    • Individuals with severe hepatic failure should likely avoid lengthy laparoscopic surgeries.
