We present our standardized technique for laparoscopic right hepatectomy, utilizing a pre-placed endoscopic nasobiliary drainage catheter to enhance intraoperative cholangiography and ensure the safe division of the right Glissonean pedicle. This technique is particularly beneficial in cases of giant hepatic hemangioma, where limited working space and distorted hilar anatomy can complicate biliary and vascular management. Key steps in the procedure include: preoperative planning with contrast-enhanced computed tomography and endoscopic retrograde cholangiopancreatography, selective hepatic arterial embolization (transcatheter arterial embolization) when necessary, appropriate patient positioning and port placement, an extrahepatic Glissonean approach, cholangiographic verification of the right hepatic duct, staged control of the right portal vein following initial parenchymal transection, and hemostatic parenchymal transection. The patient's postoperative course was uneventful, and the patient was discharged on postoperative day 9 without complications.
