Robot-assisted laparoscopic cholecystectomy is safe but offers no significant advantages over human assistance. Further high-quality trials are needed to clarify the role of robotic systems in this procedure.

Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Comparative Effectiveness Research

Background:

  • The effectiveness of robotic assistants in laparoscopic cholecystectomy remains debated, with conflicting evidence on their advantages over human assistants.
  • The optimal type of robotic assistant for this procedure is not yet established.

Purpose of the Study:

  • To compare the safety of robot-assisted versus human-assisted laparoscopic cholecystectomy.
  • To evaluate the potential of robotic systems to replace human assistants in this surgical procedure.

Main Methods:

  • A systematic review of randomized clinical trials comparing robot and human assistants in laparoscopic cholecystectomy.
  • Data extraction and analysis using fixed-effect and random-effects models to calculate risk ratios and mean differences.

Main Results:

  • Five trials with 453 patients were included, all with a high risk of bias.
  • No statistically significant differences were found in morbidity, conversion rates, operating time, or hospital stay between robot and human assistants.
  • Instrument set-up time was longer for robotic assistance, and surgeons sometimes preferred the robot, though accuracy and error rates were similar.

Conclusions:

  • Robot-assisted laparoscopic cholecystectomy is a safe alternative but does not demonstrate significant benefits over human-assisted procedures.
  • There is a lack of comparative trials evaluating different types of robotic assistants.
  • Further high-quality, low-bias randomized trials are necessary to definitively assess robotic assistance in laparoscopic cholecystectomy.
