BACKGROUND AND OBJECTIVES: Laparoscopic liver resection for lesions adjacent to major vasculature can be challenging, and many would consider it a contraindication. Recently, however, laparoscopic liver surgeons have been pushing boundaries and approached some of these lesions laparoscopically. We assessed feasibility, safety and oncological efficiency of this laparoscopic approach for these lesions. METHODS: This is a monocenter study (2003-2013) describing technique and outcomes of laparoscopic liver resection for lesions adjacent to major vasculature: <2 cm from the portal vein (main trunk and first division), hepatic arteries or inferior vena cava. RESULTS: Thirty-seven patients underwent laparoscopic liver resection (LLR) for a lesion adjacent to major vasculature. Twenty-four (65%) resections were for malignant disease and 92% R0 resections. Conversion occurred in three patients (8%). Mean operative time was 313 min (standard deviation (SD) ± 101) and intraoperative blood loss 400 ml (IQR 213-700). Clavien-Dindo complications > II occurred in two cases (5%), with no mortality. Lesions at <1 cm were larger (7.2 cm (2.7-14) vs. 3 cm (2.5-5), p = 0.03) and operation time was longer (344 ± 94 vs. 262 ± 92 min, p = 0.01) than lesions at 1-2 cm from major vasculature. CONCLUSIONS: Lesions <2 cm from major hepatic vasculature do not represent an absolute contraindication for LLR when performed by experienced laparoscopic liver surgeons in selected patients.
