Hand-assisted laparoscopic surgery (HALS) allows surgeons to use a hand in minimally invasive procedures, restoring tactile sensation and improving control. This technique offers advantages for both novice and experienced surgeons in complex operations.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Laparoscopic Surgery

Background:

  • Laparoscopic surgery offers benefits but can be limited by lack of tactile feedback and retraction difficulties.
  • Hand-assisted laparoscopic surgery (HALS) emerged to address these limitations by integrating a surgeon's hand into the laparoscopic procedure.

Purpose of the Study:

  • To describe the principles, applications, and advantages of hand-assisted laparoscopic surgery (HALS).
  • To evaluate the impact of HALS on surgical outcomes and the learning curve for laparoscopic procedures.

Main Methods:

  • Description of HALS technique, emphasizing device engineering and proper port placement principles.
  • Review of HALS application in specific procedures: laparoscopic splenectomy, live-donor nephrectomy, and sigmoid colectomy.

Related Experiment Videos

  • Discussion of HALS's role in facilitating advanced laparoscopic procedures for surgeons of all experience levels.

    • Main Results:

    • HALS restores tactile sensation, enables atraumatic retraction, blunt dissection, and digital vascular control.
    • Proper device placement is crucial, guided by principles like port-site triangulation and ergonomic considerations.
    • HALS demonstrated advantages in splenomegaly, live-donor nephrectomy, and sigmoid colectomy without compromising laparoscopic benefits.

    Conclusions:

    • Hand-assisted laparoscopic surgery (HALS) offers significant advantages, enhancing surgeon's capabilities in minimally invasive procedures.
    • HALS may shorten the learning curve for advanced laparoscopic surgery and reduce conversion rates for experienced surgeons.
    • The technique holds promise for expanding the role of minimally invasive approaches in various complex surgical operations.
