A unique rat liver hilar clamp model was developed for studying the impact of pharmacologic molecules in ameliorating ischemia-reperfusion injury. This model includes direct cannulation of the portal supply to the ischemic liver segment via a branch of the portal vein, allowing for direct hepatic delivery.

The zebrafish kidney is home to both renal and hematopoietic adult stem/progenitor cells, and represents an outstanding opportunity to study these cell types and their progeny in a vertebrate model organism. Here, we demonstrate a detailed dissection procedure that enables the researcher to identify and surgically remove the adult zebrafish kidney, which can be used for applications such as cell isolation, transplantation, and expression studies of kidney and/or blood cell populations.

FAQs
Defined tissue planes provide a deliberate route through the hilum, helping the surgeon expose relevant structures while limiting injury to adjacent tissue. This controlled progression also supports bleeding management because vessels can be identified before they are ligated or divided. The result is greater operative control in anatomically complex regions.
Accurate identification allows the surgeon to decide whether a vessel, duct, nerve, or connective-tissue component should be preserved, ligated, divided, or reconstructed. These choices depend on the structure’s operative role and the planned procedure. Careful differentiation therefore connects anatomical exposure with safe organ removal, repair, or implantation.
The hilum contains multiple structure types in a compact, complex anatomical region, and errors can cause bleeding or injury to nearby tissues. Thoracic and hepatobiliary operations also have different operative objectives, including resection, removal, or implantation. Mastery requires reliable anatomical identification while maintaining control throughout the dissection.
In lung resection and liver surgery, hilar exposure helps the surgeon identify the structures that must be preserved, controlled, divided, or reconstructed for the planned operation. This anatomical control supports organ removal while limiting bleeding and adjacent-tissue injury. The technique is therefore relevant to both thoracic and hepatobiliary surgical planning.
During transplantation, the technique helps expose and identify the structures required for organ removal from one setting and implantation into another. Accurate recognition of vessels, ducts, nerves, and surrounding tissue supports controlled reconstruction and helps avoid unintended injury. Its value is especially important when complex hilar anatomy must be managed during implantation.
Yes. Hilar dissection supports both open and minimally invasive procedures, although the access method differs. In either setting, the essential objective remains accurate anatomical identification followed by controlled preservation, ligation, division, or reconstruction. Applying the same principles across approaches can improve operative control and help reduce procedure-related complications.
