Hand-assisted laparoscopic surgery (HALS) offers a safe and efficient alternative to traditional laparoscopy. This method improves surgical action efficiency, combining open surgery benefits with minimally invasive advantages.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Advanced laparoscopic surgery presents challenges in efficacy and safety.
  • Hand-assisted laparoscopic surgery (HALS) was developed to address these complexities.

Purpose of the Study:

  • To evaluate the safety and efficiency of HALS compared to conventional laparoscopy.
  • To assess the impact of HALS on surgical performance metrics.

Main Methods:

  • HALS devices allow manual abdominal access during laparoscopy, restoring tactile sensation and hand-eye coordination.
  • Safety of HALS devices was verified through randomized controlled trials (RCTs).
  • Surgical Action Efficiency (SAE) was calculated for patients undergoing colon resection via laparoscopy versus HALS.

Main Results:

Related Experiment Videos

  • All registered HALS devices demonstrated safety.
  • SAE was significantly higher in the HALS group (71% ± 4%) compared to the laparoscopy group (55% ± 14%), with p < 0.05.
  • The study confirms the statistical significance of HALS's improved efficiency.

Conclusions:

  • HALS is a safe and efficient surgical approach.
  • HALS effectively merges the benefits of open surgery with those of minimally invasive techniques.
  • The findings support HALS as a valuable advancement in surgical practice.
