Laparoscopic dissection of the first and second porta hepatis along Laennec's capsule via “Hepatic Serosal Incision” approach: How I do it

Abstract

AbstractTo provide a standardized approach for laparoscopic access to dissection of the first and second porta hepatis. By opening a portion of the hepatic serosa and subsequently exposing the hepatic Laennec's capsule, dissection of the first and second porta hepatis was performed along the Laennec's capsule. Utilizing the “Hepatic Serosal Incision” approach along the Laennec's capsule enabled the precise dissection of the left and right hepatic pedicles of the first porta hepatis and the root of the hepatic veins at the second porta hepatis under laparoscopy. This method allows for rapid and accurate access to the space between Laennec's capsule and the hepatic hilar plate system under laparoscopy as well as clear exposure of the root of the hepatic veins and their branches, facilitating more precise laparoscopic anatomical liver resection.
