Partial splenectomy with the CO2 laser: an alternative technique.

M Reynolds, J LoCicero, S Young

    The Journal of Surgical Research
    |December 1, 1986

    Summary

    CO2 laser sealing of splenic wounds offers excellent hemostasis with minimal injury and fewer adhesions compared to traditional suture repair. This technique presents a promising alternative for partial splenectomy procedures.

    Area of Science:

    • Surgical Innovation
    • Minimally Invasive Techniques
    • Gastrointestinal Surgery

    Background:

    • Partial splenectomy is preferred over total splenectomy to preserve immunocompetence.
    • Conventional splenic repair involves extensive suturing, leading to significant intra-abdominal adhesions.

    Purpose of the Study:

    • To evaluate CO2 laser sealing as an alternative hemostatic technique for splenic wounds.
    • To compare the incidence of adhesions and tissue damage between laser sealing and suture repair.

    Main Methods:

    • Partial splenectomy was performed on five dogs using a scalpel.
    • Hemostasis was achieved using a defocused CO2 laser at 8 W.
    • Splenic tissue treated with laser was later removed and compared to conventionally sutured tissue.

    Main Results:

    • CO2 laser sealing provided excellent hemostasis with minimal splenic tissue injury (2-3 mm depth).
    • Laser-treated spleens showed minimal adhesions, while sutured spleens exhibited dense adhesions involving surrounding organs.
    • No hemorrhage was observed in laser-sealed wounds during exploration.

    Conclusions:

    • CO2 laser sealing is an effective method for achieving hemostasis in partial splenectomy.
    • This technique minimizes intra-abdominal adhesions and foreign material, offering an advantage over suture repair.
