2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

FAQs
Anatomical landmarks help surgeons distinguish segment VII from adjacent liver tissue, particularly in the posterior-superior right hepatic lobe. Their identification supports planning of the resection plane and helps align the operation with the segment’s vascular inflow and venous drainage. This anatomical guidance is important for removing the intended tissue while limiting disruption of uninvolved liver.
Segmental vascular relationships determine how surgeons control blood supply to the target tissue and manage its venous drainage. Understanding these connections helps define the operative boundaries before the surrounding hepatic parenchyma is divided. Careful vascular planning therefore supports accurate segment removal and contributes to safer preservation of liver tissue that does not contain disease.
The segmental approach targets localized disease while retaining uninvolved portions of the right hepatic lobe. In contrast, removing the entire lobe sacrifices a larger volume of liver tissue. When adequate margins can be achieved, this parenchyma-sparing strategy may preserve more functional liver and avoid a more extensive anatomical removal.
Preoperative imaging helps identify the location and extent of the target lesion in relation to segment VII and nearby vascular structures. Surgeons use that information to assess whether the disease is sufficiently localized and whether adequate margins appear achievable. The imaging plan then complements intraoperative landmarks when the resection boundaries are confirmed during surgery.
The operation begins with localization of segment VII using preoperative information and intraoperative anatomical landmarks. Surgeons then control the segment’s vascular inflow and venous drainage before dividing the surrounding hepatic parenchyma along the planned resection plane. This sequence connects anatomical identification with vascular control and selective tissue removal.
Surgeons may consider this operation for selected tumors or other localized liver disease when the affected area is confined enough to permit adequate margins. The approach is relevant when preserving uninvolved liver is important and a complete right-lobe removal is unnecessary. It can also inform both minimally invasive and open hepatobiliary procedures.
