Summary

Infection plays a role in acute acalculous cholecystitis. Diclofenac (NSAID) did not impact gallbladder lesions or bile infection in this animal study.

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Microbiology

Background:

  • Infection is a secondary factor in gallstone-induced acute cholecystitis.
  • The role of infection in acute cholecystitis without gallstones requires further clarification.
  • This study investigates infection in acute acalculous cholecystitis using an animal model.

Purpose of the Study:

  • To investigate the significance of infection in acute acalculous cholecystitis.
  • To evaluate the effect of Diclofenac (NSAID) on bile microbiology in pigs with induced acute cholecystitis.

Main Methods:

  • Acute cholecystitis was induced in pigs via biliary pedicle ligation and lysophosphatidylcholine administration.
  • Two groups were studied: P1 (no Diclofenac) and P2 (treated with Diclofenac).

  • Bile microbiology and histological gallbladder lesions were analyzed.

    • Main Results:

    • 82.3% of animals developed severe acute cholecystitis lesions.
    • Positive bile cultures were observed in 64.1% of the control group (P1) and 65.5% of the Diclofenac group (P2).
    • Diclofenac administration did not significantly alter gallbladder lesions or bile microbial agents compared to controls.

    Conclusions:

    • Infection is a significant factor in acute acalculous cholecystitis.
    • Diclofenac does not appear to influence histological gallbladder lesions or bile infection in this model of acute acalculous cholecystitis.
