Application of the Laennec capsule approach in laparoscopic anatomical sectionectomy / 中华消化外科杂志

ABSTRACT

Laparoscopic anatomic hepatectomy (LAH) has been widely approved as an essential procedure for safety and availability, and has gradually become the mainstream method of hepatec-tomy. Through a renewed understanding of the Laennec capsule, the authors have found that there exists a natural gap between the Laennec capsule and the adjacent tissues, such as Glisson pedicles and hepatic veins. Consequently, Laennec capsule can serve as the anatomical approach for LAH. The left lobe, right anterior lobe and right posterior lobe has an independent Glisson pedicle respectively, which can be used to perform Glisson pedicle transection sectionectomy via Laennec capsule approach without damaging the liver parenchyma. The exposure of hepatic veins on the detached plane can also be achieved through this approach. Laennec capsule approach provides a new idea for laparoscopic anatomic liver sectionectomy, which is safe, reliable, convenient and highly repeatable.
