    Laparoscopic liver resection (LLR) is increasingly adopted and supported by international consensus for selected indications.

  • 2

    Safe LLR relies on stable visualization and effective camera navigation, which can be improved through structured training.

  • 3

    The study evaluated 161 LLRs performed by a single surgeon, comparing outcomes between expert and novice scopists.

  • 4

    Olympus 3D flexible scopes were operated using either a dual-lever or joystick controller, potentially affecting learning curves.

  • 5

    Statistical analyses included comparisons of operation time and perioperative outcomes based on scopist experience and controller type.
