    Area of Science:

    • Surgical Innovation
    • Biomaterials Science
    • Gastroenterology

    Background:

    • Acute gastric defects pose surgical challenges.
    • Prosthetic materials are explored for tissue repair.
    • Evaluating biomaterial integration in the stomach is crucial.

    Purpose of the Study:

    • To assess the safety and efficacy of using dacron patches for acute stomach defects in rabbits.
    • To evaluate the tissue integration and long-term fate of the prosthetic material.
    • To explore potential clinical applications for gastrointestinal fistula treatment.

    Main Methods:

    • Acute gastric defects were surgically created in rabbits.
    • Dacron patches were utilized for defect closure.
    • Postoperative monitoring included assessment of tissue integration and material fate.

    Main Results:

    • No procedure-related deaths occurred.
    • Complete tissue coverage of the dacron patch was observed within 6 weeks.
    • Evidence of material rejection appeared by 6 months, with the patch found in granulation tissue at 1.5 years.

    Conclusions:

    • The dacron patch technique for stomach defect closure is simple, safe, and yields satisfactory initial results.
    • Long-term observations indicate potential for prosthetic material rejection.
    • The method shows promise for clinical use in selected gastrointestinal fistula cases.
