Comparing Practice and Outcome of Laparoscopic Liver Resection Between High-volume Expert Centres and Nationwide Low-medium Volume Centres

Purpose: It is unknown how use and outcome of laparoscopic liver resection (LLR) compare between high-volume centres (HV) low-medium volume (LMV). This study aimed to LLR according surgical difficulty in three leading European HV twenty Dutch LMV. Method: An international, retrospective multicentre cohort including data from LMV January 2011 December 2016. are defined by performing >50 annually. Patients were retrospectively stratified into low-, moderate- high-risk Southampton strata. Results: 2425 patients included (1540 HV; 885 LMV). The annual was higher than (42.9% versus 7.2%). experienced fewer conversions (7.4 13.1%; P<0.001) less intraoperative incidents (9.3% 14.6%; P=0.002) compared Whereas morbidity mortality rates similar, intervention rate (5.1% 7.2%; P=0.034) postoperative hospital stay (3 5 days; lower Per score stratum, the conversion HV. similar low-risk however moderate-risk strata (absolute difference 6.7% 14.2%; P<0.004). Conclusion: had a sixfold LLR, conversions, shorter stay, as nationwide Stratification scores identified some differences but largely outcomes appeared better for each risk group.
