AbstractThe technique of laparoscopic liver resection (LLR) has been greatly improved since the first international consensus conference. Our aim was to evaluate the worldwide spread of LLR prior to the 2nd International Consensus Conference on Laparoscopic Liver Resection in Iwate, Japan (4-6 October 2014). The International Survey on Technical Aspects of Laparoscopic Liver resection was designed to assess dissemination of LLR, indications, and the surgical techniques. The anonymous questionnaire was e-mailed to liver surgeons worldwide. A total of 448 liver surgeons responded to the survey. The peak age range of surgeons performing LLR was 41-50 years. Japan had by far the largest number of respondents (n = 223), followed by the US (n = 38) and France (n = 20). In Japan, the majority of surgeons performing LLR belonged to community hospitals, where LLR has been increasingly used since its implementation in 2009 or later, comprising up to 40% of all liver resection cases. In contrast, in North America and Europe, LLR was mostly performed at academic medical centers. LLR has undergone global dissemination after the first international consensus conference in 2008. Japan has experienced unparalleled, explosive diffusion characterized by the adoption of LLR at middle-tier, regional institutions. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.
