Robotic Liver Surgery
Backgrounds
1. Lesion size: No limits. Exclusion of sub-capsular extension and major vessels
infiltration.
2. Location: All the segments except segment I. (Posterior segment when a major
hepatectomy is required).
3. Extension:
Left lateral Sectionectomy, Segmentectomy,
Bisegmentectomy, Major Hepatectomies, Extended Hepatectomy
4. Pathology: Benign lesions (selected),
Malignant lesions: -HCC
- CRLM/ NCRLM
- Hilar malignancy
5. Pediatric and Adult Living donor: limited experience
6. Contraindications: Subcapsular extension, Invasion of Major Hepatic Vessels,
(Portal vein resection).
Laparoscopic Liver Surgery
Backgrounds
1992
First laparoscopic liver resection
Gagner et al. Surg Endosc 1992; 6: 99.
1996
First anatomic laparoscopic liver resection
Azagra et al. Surg Endosc 1996; 10: 758-761.
1997
First laparoscopic major liver resection
Huscher et al. J R Coll Surg Edinb 1997; 42: 219-225.
Laparoscopic Liver Surgery
Consensus
• Currently acceptable indications: solitary lesions, 5 cm or less, located in liver
segments 2 to 6
• Major liver resections should be reserved for experienced surgeons
• Conversion should not be considered as a failure
• Utilization of a hand assist or hybrid technique may be faster and safer
• Laparoscopic liver surgery has not been tested by controlled trials for
efficacy or safety
• A prospective randomized trial appears to be logistically prohibitive
• An international registry should be initiated to document the role and
safety of laparoscopic liver resection.
Laparoscopic Liver Surgery
Limitations
• Surgical skills
• Previous laparotomy
• Tools and instruments (suturing, retraction…)
• Location of the lesions (posterior segments)
• Extension of resection (major resections)
• Complex resections and reconstruction (hilar
cholangiocarcinoma)
Robotic Liver Surgery
Robotic Liver Surgery: Backgrounds
background
 In the current literature, only few small robotic series
 Good clinical results
 Robotic facilitate liver resection
 Especially for procedures that require a small operating field
 Left lateral sectionectomy is the first step in the learning curve

Conclusions
 Robotic surgery is safe and feasible in experienced hands
 The technical abilities of the robotic system might improve the
critical steps of minimally invasive major liver resections
 Only robotics make feasible complex minimally invasive liver
resections
 Robotic surgery may expand the indications for minimally
invasive liver surgery
Conclusions
 For oncology, robotic surgery is one of the tool to extend the limit
of minimally invasive surgery in the field of liver resections
 Probably achieves the same oncological results as open approach
 Achieves low morbidity and mortality rate
 Reopens the possibilities of minimally invasive surgery
