腹腔鏡下左外側切片切除術:肝靭帯と臍裂静脈による指導

Executive Industry Relevance

Precise anatomical guidance in laparoscopic left lateral sectionectomy (LLLS) addresses a critical challenge in minimizing intraoperative bleeding, especially when controlled low central venous pressure is contraindicated. Leveraging the ligamentum teres hepatis and umbilical fissure vein as landmarks enhances surgical accuracy and safety, supporting broader applicability across patient populations. This approach strengthens procedural predictability and operational confidence at key inflection points in surgical innovation pipelines.
