    Histologic diagnoses from liver lobe biopsies showed significant overlap in 57 patients. Key parameters like inflammation and fibrosis strongly correlated between biopsy sites, supporting their reliability.

    Area of Science:

    • Hepatology
    • Surgical Pathology
    • Medical Diagnostics

    Background:

    • Accurate liver histology is crucial for diagnosing and managing liver diseases.
    • Laparoscopic liver biopsy is a common diagnostic procedure.
    • Assessing the consistency of histological findings between different liver lobes is important for diagnostic reliability.

    Purpose of the Study:

    • To evaluate the concordance of histological diagnoses obtained from right and left liver lobe laparobiopsies.
    • To determine the correlation of specific histological parameters (inflammation, fibrosis, necrosis, steatosis) between paired biopsies.

    Main Methods:

    • Laparobiopsies were performed on the right and left liver lobes of 57 patients.
    • Histological examination and scoring of key parameters including inflammation, fibrosis, necrosis, and steatosis were conducted for each biopsy.

  • Statistical analysis was used to compare diagnoses and correlate histological scores between the two biopsy series.

    • Main Results:

    • Histological diagnoses from the right and left liver lobes demonstrated considerable overlap, indicating good concordance.
    • A highly significant correlation was observed for individual histological parameters (inflammation, fibrosis, necrosis, steatosis) between the two biopsy sites.
    • Minor discrepancies in diagnoses were noted but did not significantly impact overall diagnostic conclusions.

    Conclusions:

    • Laparobiopsies from different liver lobes provide largely overlapping and consistent histological diagnoses.
    • The high correlation of histological parameters supports the reliability of assessing liver disease severity using biopsies from either lobe.
    • These findings validate the use of laparobiopsies from multiple sites for comprehensive liver disease evaluation.
