Area of Science:

  • Surgical techniques
  • Medical imaging analysis
  • Computational anatomy

Background:

  • Laparoscopic surgery requires precise port placement for safe access to target organs.
  • Optimal port positioning is critical in laparoscopic gastrectomy to avoid vital anatomical structures.

Purpose of the Study:

  • To present a method for determining optimal port placement in laparoscopic gastrectomy.
  • To base port placement on the spatial relationships between ports and critical anatomical structures.

Main Methods:

  • Utilized three angle conditions derived from measurements during laparoscopic gastrectomy.
  • Analyzed angle relationships between port locations and vital anatomical structures identified via CT scans.
  • Determined optimal port placement using a 3D positional tracker for experienced surgeon-defined positions.

Main Results:

  • The proposed method was evaluated on 26 laparoscopic gastrectomies.
  • Achieved average placement errors of 22.2 mm (left) and 21.2 mm (right) for the lead surgeon.
  • Experienced surgeons deemed the generated placements clinically adequate.

Conclusions:

  • The method facilitates optimal port placement in laparoscopic gastrectomy.
  • Enables less experienced surgeons to achieve port placements similar to those of experts.
