Laparoscopic anatomical right hepatectomy using a four-incision anterior approach: Technical details and surgical outcomes (with Video).

With the continuous advancements of laparoscopic techniques, many surgeons have enhanced the feasibility and safety of this approach for carefully selected patients. This study aims to offer a comprehensive account of the technical aspects and surgical outcomes associated with laparoscopic anatomical right hepatectomy, explicitly utilizing a four-incision anterior approach. The surgical procedure involved several maneuvers, including blocking the Glissonean pedicle, ligation of the right hepatic artery, right branch of the portal vein, and the right hepatic duct, removal of the liver parenchyma along the ischemic line, and determination of the liver section based on four anatomical landmarks: the right anterior Glissonian pedicle, middle hepatic vein, root of the right hepatic vein, and retrohepatic inferior vena cava. The article provides clear visualization of these anatomical landmarks following right hepatectomy. Proper patient positioning and precise incision placement are crucial factors for ensuring the success of the laparoscopic right anterior hepatectomy procedure. The separation of the extrahepatic Glissonean pedicle at the liver hilum to determine the hepatic resection ischemia line, as well as the identification of liver sections using four anatomical landmarks are essential steps in the liver resection process. The laparoscopic anatomical right hepatectomy using a four-incision anterior approach was performed smoothly, with standard intraoperative techniques completed. Measures are in place to address any complications that may arise during the surgery.
