Abstract

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.
