    Area of Science:

    • Gastroenterology
    • Medical Technology
    • Laser Applications

    Background:

    • Flexible fibers enabled endoscopic laser delivery in the 1970s.
    • Extensive experience has been gained in gastrointestinal tract applications.
    • Associated risks are considered minimal.

    Purpose of the Study:

    • To review the established and emerging applications of endoscopic laser therapy in the gastrointestinal tract.
    • To highlight the therapeutic benefits and safety profile of laser energy in gastroenterology.
    • To discuss future innovative directions in endoscopic laser technology.

    Main Methods:

    • Review of historical development and clinical applications of endoscopic lasers.
    • Analysis of the mechanisms of action: coagulation and ablation.
    • Discussion of current and potential future laser modalities and delivery systems.

    Main Results:

    • Coagulative laser effects are utilized for gastrointestinal hemorrhage and benign mucosal lesions.
    • Ablative effects of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) lasers treat malignant disorders and anatomical lesions (strictures, cysts).
    • Minimal risks associated with endoscopic laser procedures.

    Conclusions:

    • Endoscopic laser therapy is a safe and effective tool in gastroenterology.
    • Current applications include hemostasis, lesion treatment, and palliative care.
    • Advancements in laser technology and delivery systems suggest a promising future with novel applications.
