    The Medical Journal of Australia
    |July 31, 1976
    PubMed
    Summary
    This summary is machine-generated.

    For stomach or esophageal carcinoma diagnosis, take a minimum of four biopsy fragments. More than eight biopsy specimens do not significantly improve diagnostic yield but increase procedure time.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Pathology

    Background:

    • Accurate histopathological examination is crucial for diagnosing gastrointestinal cancers.
    • Biopsy procedures are essential for obtaining tissue samples for diagnosis.

    Purpose of the Study:

    • To determine the optimal number of biopsy fragments for diagnosing stomach and esophageal carcinoma.
    • To evaluate the impact of biopsy specimen количество on diagnostic accuracy and procedure time.

    Main Methods:

    • Review of endoscopic biopsy procedures for suspected gastric and esophageal carcinoma.
    • Analysis of histopathological examination data based on the number of biopsy fragments obtained.

    Main Results:

    • A minimum of four biopsy fragments are recommended for confirming or excluding stomach or esophageal carcinoma.

  • Taking more than eight biopsy specimens did not substantially increase diagnostic value.
  • Excessive biopsy numbers prolonged the procedure time for the medical team.

    • Conclusions:

    • Four biopsy fragments represent an effective balance between diagnostic yield and procedural efficiency.
    • Optimizing the number of biopsy specimens can improve resource utilization in gastrointestinal cancer diagnosis.
