Background: While inflow control can be easily applied by Pringle maneuver, outflow control of the left liver has not been formally described. We report here a safe and reproductible technique of middle and left hepatic veinous trunk control (MLHVC) before parenchymal transection during laparoscopic left hepatectomy.
Methods: A retrospective review of laparoscopic liver resection was conducted from January 2013 to March 2018 from our prospective database. All cases of laparoscopic left hepatectomy (LLH) were included, and intra- and postoperative outcomes data collected. We collected cases where the middle and left hepatic vein trunk control has been attempted and clamping used, and we analyzed outcomes associated with this maneuver.
Results: MLHVC was attempted in 28 cases (77.8) of the 36 LLH identify in a monocentric study. It was technically not feasible only in 3 cases (8.3%) and clamping applied in 15 cases (41.7%). No significant intraoperative unexpected event occurred.
Conclusion: We present here a technique for left liver outflow control that can be safely added to the armamentarium of laparoscopic liver surgery.
