Background
Despite diffusion of laparoscopic hepatectomy, the acquisition of necessary skills is not easy for open liver surgeons. Concepts and techniques have totally changed in laparoscopic hepatectomy compared with open hepatectomy, which is an underlying cause of a technical hurdle in laparoscopic hepatectomy. This study aimed to illustrate laparoscopy-specific concepts and techniques for hepatectomy.
Methods
Video footages of laparoscopic and open hepatectomies stored in the Institut Mutualiste Montsouris and Kyoto University were reviewed to define the differences in surgical view, surgical concept, and technical details, using left lateral sectionectomy (LLS) and right hepatectomy (RH) as representative examples.
Results
By comparison with open LLS and RH, laparoscopy-specific procedures were identified with regard to surgical view, parenchymal transection, available landmarks, and vascular dissection. By laparoscopy, the surgical field was constantly viewed and accessed from the caudal side to the cranial side. Similarly, the parenchyma was divided, and intrahepatic vessels were dissected in the same direction. Laparoscopy-specific landmarks were identified for both LLS and RH, behind the liver.
Conclusions
The concepts and techniques in laparoscopic hepatectomy are totally different from those of open hepatectomy because of the different surgical views. Understanding the laparoscopy-specific concepts and techniques would facilitate safe and efficient execution of laparoscopic hepatectomy.
