    Area of Science:

    • Gastroenterology
    • Endoscopic Procedures
    • Histopathology

    Background:

    • Bioptic sampling in the esophagus and gastric prepyloric lesser curvature often yields inadequate tissue.
    • Histologic diagnosis relies on sufficient and high-quality tissue samples.

    Purpose of the Study:

    • To introduce and evaluate a new technique for aimed bioptic sampling.
    • To improve the quality of tissue fragments obtained from challenging anatomical areas.

    Main Methods:

    • Development of a new technique for targeted tissue collection.
    • Utilized front-view instruments and standard forceps for sampling.
    • Focused on difficult-to-access regions like the esophagus and gastric prepyloric lesser curvature.

    Main Results:

    • The new technique enables the acquisition of satisfactory tissue fragments.
    • Achieved successful sampling even with conventional endoscopic tools.
    • Overcame limitations of previous methods in specific gastrointestinal locations.

    Conclusions:

    • The described technique enhances the reliability of bioptic sampling in the upper gastrointestinal tract.
    • It provides suitable material for accurate histologic diagnosis from previously challenging sites.
