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.

Infection of mice with an Adenovirus expressing the major human autoantigen cytochrome P450 2D6 (hCYP2D6) recognized by sera of patients suffering from type 2 autoimmune hepatitis results in a persistent form of autoimmune-mediated liver disease characterized by extensive hepatitis, fibrosis and generation of a CYP2D6-specific immune response.

Marginating-hepatic leukocytes exhibit unique characteristics and distinct immunological functions compared to other leukocyte populations. Here we describe a method for selective harvesting of this specific hepatic cell population, through forced perfusion of the liver of rats or mice. Marginating-hepatic leukocytes seem critical in determining susceptibility to hepatic-related diseases and metastases.
FAQs
The central principle is to balance tumor removal with preservation of viable liver. Surgeons select the amount and location of transection so that sufficient functional parenchyma remains after the diseased area is removed. This balance matters because postoperative recovery and liver function depend not only on local tumor control, but also on the capacity of the retained tissue to support the patient.
Choosing an anatomical or nonanatomical transection gives surgeons two planning approaches for separating the targeted portion from the liver that remains. The selected approach must fit the diseased or tumor-bearing tissue while maintaining adequate functional parenchyma. In cancer research, this planning choice is therefore tied to both the completeness of local treatment and the preservation needed for recovery.
Vessels and bile ducts are managed because they are structures encountered when the targeted liver portion is separated. Surgeons isolate and divide them while controlling bleeding, linking structural division to operative bleeding control. This coordination is important in cancer-focused resections because the procedure must remove the intended tissue while leaving enough functioning parenchyma to support recovery and subsequent liver function.
A supported operative sequence includes planning the transection, isolating and dividing the relevant vessels and bile ducts, and controlling bleeding as the targeted portion is separated. These steps connect the planned resection with division of structures serving the operative field. The result is then considered in relation to the remaining liver, whose preserved function supports recovery.
The removed tissue can undergo pathological and molecular analysis, allowing researchers and clinicians to examine tumor-bearing material beyond the operation itself. It can also support assessment of surgical margins, which shows how the resection relates to the edges of removed tissue. These findings connect the procedure with cancer characterization and evaluation of recurrence risk.
The operation provides a context for examining liver regeneration because a portion of the liver is removed while functional parenchyma is deliberately retained. Researchers can relate tissue removal to recovery of liver function and to the behavior of the remaining liver. This makes regeneration a relevant outcome alongside tumor control and pathological analysis.
This approach is relevant for selected primary liver cancers and liver metastases when local tumor control is an objective. In treatment, the resection addresses tumor-bearing tissue while preserving remaining liver function. In research, the same operation generates information about pathological and molecular features, surgical margins, recurrence risk, and regeneration, linking clinical treatment with biological investigation.
