Robotic Liver Surgery PC Giulianotti, MD, FACS Professor and Chief Division of General, Minimally Invasive and Robotic Surgery University of Illinois Medical Center at Chicago Robotic Surgery The UIC program Robotic Surgery The UIC program 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 Giulianotti PC et al.
