The Laennec capsule of liver was first discovered and reported by French doctor Rene Theophile Hyacinthe Laennec in 1802.However, it has not received enough attention for more than 200 years since then. In recent years, with the rapid development of liver surgery represented by laparoscopic technology, and the deepening of the theory of precise liver surgery, the fine anatomical structure of liver Laennec capsule has returned to the vision of liver surgeons.Recent studies have demonstrated the presence of Laennec capsule in liver histology, covering the whole liver surface, and lining the surface of liver parenchyma around the Glisson pedicle and the main hepatic vein along the inflow and outflow channels of the liver. Based on the Laennec capsule approach, it is expected to unify the current approach of Glisson pedicle and the approach of hepatic vein, and provide a new theoretical basis for the liver surgery, and guide us in the standardization of liver surgeries.
肝脏Laennec包膜最早于1802年由法国医师Laennec发现并报道，但在此后200余年未得到足够重视。近年来，随着腹腔镜肝脏外科的快速发展，以及精准肝切除理念的不断深入，肝脏的精细解剖结构——Laennec包膜重新回到外科医师的视野中。最近有学者在组织学上证实了肝脏Laennec包膜的存在，发现其覆盖在整个肝脏表面，同时沿着肝脏的流入道和流出道衬于Glisson鞘和肝静脉周围肝实质的表面。因此，基于Laennec包膜的肝切除手术入路，有望将目前的Glisson鞘入路和肝静脉入路统一，为建立规范和标准化的肝脏手术方式提供新的思路。.
