Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics
  • Laparoscopic Surgery

Background:

  • Robotic-assisted surgery offers advantages over standard laparoscopic surgery, including enhanced optics, ergonomics, dexterity, and precision.
  • Conventional laparoendoscopic single-site surgery (LESS) faces constraints like instrument clashing, poor triangulation, and difficult intracorporeal suturing.
  • Robotics applied to LESS (R-LESS) aims to overcome these limitations.

Purpose of the Study:

  • To evaluate the feasibility and challenges of robotic-laparoendoscopic single-site surgery (R-LESS).
  • To compare R-LESS outcomes with conventional LESS and standard robotic surgery.

Main Methods:

  • A systematic literature review was conducted using PubMed.
  • Search terms included variations of robotic single-site, single-port, and single-incision surgery.
  • Included studies were in English, with no time restrictions.

Main Results:

  • R-LESS minimizes difficulties found in conventional LESS, such as intracorporeal suturing and triangulation.
  • Outcomes are comparable to standard robotic surgery, with a trend towards improved cosmesis and reduced pain, though not yet statistically significant.
  • No prospective studies on R-LESS have been published to date.

Conclusions:

  • R-LESS is technically feasible, leveraging robotic benefits to address conventional LESS challenges.
  • Persistent issues include instrument clashing, limited assistant space, and retraction difficulties.
  • R-LESS technology is still in its early stages, with ongoing development for solutions.
