What are the advantages and disadvantages of laparoscopic (minimally invasive surgical procedure using a laparoscope) versus robotic liver resection?

Laparoscopic vs Robotic Liver Resection: Advantages and Disadvantages

Laparoscopic liver resection is recommended over robotic liver resection due to its proven benefits in reducing postoperative length of stay and complication rates, while robotic liver resection lacks sufficient high-quality evidence despite showing promising results in recent studies. 1

Minimally Invasive Approaches to Liver Resection

Laparoscopic Liver Resection

• Established Benefits:

  • Reduced intraoperative blood loss compared to open surgery 1
  • Lower postoperative morbidity rates 1
  • Shorter hospital stays 1
  • Lower postoperative morphine consumption 1
  • Better quality of life outcomes 1
  • Does not compromise oncological outcomes 1

• Evidence Quality:

  • Strong recommendation with moderate evidence level in ERAS Society guidelines 1
  • Multiple RCTs supporting benefits for minor liver resections 1
  • Meta-analyses and propensity score studies supporting benefits for major hepatectomies 1
  • Endorsed by international consensus conferences (Louisville, Morioka, Southampton) 1

• Best Applications:

  • Particularly beneficial for tumors in anterolateral and superficial locations 1
  • Well-established for left lateral sectionectomy 1
  • Increasingly used for major hepatectomies by experienced teams 1

Robotic Liver Resection

• Potential Advantages:

  • Three-dimensional visualization 2
  • Enhanced instrument dexterity and precision 2
  • Lower readmission rates (8.7% vs 12.9% for laparoscopic) 3
  • Lower complication rates in some studies (7.3% vs 9.1% for laparoscopic) 3
  • Lower estimated blood loss compared to open surgery 4
  • Lower conversion rates to open surgery compared to laparoscopic approach 5, 6
  • May facilitate complex hepatectomies in posterosuperior segments 6

• Limitations:

  • Lack of high-quality evidence from RCTs 1
  • Higher costs compared to laparoscopic approach 6
  • Longer operative times in some studies 4
  • Limited long-term outcome data 2

Comparative Outcomes

Short-term Outcomes

• Blood Loss:

  • Both approaches show reduced blood loss compared to open surgery 4, 5
  • Some evidence suggests robotic approach may have less blood loss than laparoscopic 6

• Complications:

  • Both approaches show lower complication rates than open surgery 4, 5
  • Recent multicenter study suggests robotic approach may have lower overall morbidity (19.3% vs 25.7%) 6

• Hospital Stay:

  • Both approaches demonstrate shorter hospital stays compared to open surgery 1, 4
  • Robotic and laparoscopic approaches show similar reductions in length of stay (39% and 43% shorter than open surgery, respectively) 5

Oncological Outcomes

• Resection Margins:

  • Both approaches can achieve comparable R0 resection rates to open surgery 4, 5
  • Some evidence suggests robotic approach may have lower rates of microscopically positive margins compared to laparoscopic (10.1% vs 13.8%) 6

• Long-term Survival:

  • Similar overall and disease-free survival between minimally invasive and open approaches 4
  • Limited long-term data specifically comparing robotic vs laparoscopic approaches

Clinical Decision Making

When to Consider Laparoscopic Approach

• First-line minimally invasive approach for most liver resections 1
• Particularly beneficial for:
  • Minor liver resections 1
  • Tumors in anterolateral segments (2,3, 4b, 5,6) 1, 6
  • Left lateral sectionectomy 1

When to Consider Robotic Approach

• May be beneficial for:
  • Complex hepatectomies in posterosuperior segments (1, 4a, 7,8) 6
  • Major hepatectomies (≥3 contiguous segments) 6
  • Cases where lower conversion rates to open surgery are critical 5, 6

Important Considerations

• Surgeon experience and training are critical factors for both approaches 1
• Center expertise and available technology should guide approach selection
• Patient factors including tumor location, size, and underlying liver disease must be considered
• Cost considerations may limit robotic approach in some settings 6

Conclusion

While both minimally invasive approaches offer advantages over open surgery, laparoscopic liver resection currently has stronger evidence supporting its use and is recommended by clinical guidelines. Robotic liver resection shows promising results in recent studies but lacks high-quality evidence from randomized trials. The choice between approaches should consider tumor characteristics, surgeon expertise, and institutional resources.
