Inducing rapid liver hypertrophy using Associating Liver Partition and Portal vein ligation for a Staged hepatectomy (ALPPS) has been proposed for resection of borderline resectable liver tumors. This model may elucidate mechanisms involved in rapid hypertrophy and allows testing of drugs that promote or block the acceleration of regeneration.

A technique for isolating portal fibroblasts from rat liver is described. Livers are perfused and digested in situ with collagenase, followed by ex vivo digestion of the liver slurry and size selection of cells. This method provides a pure population of portal fibroblasts without the need for passage in culture.
FAQs
A planned transection plane guides removal through the intended portion of liver while limiting unnecessary loss of functioning tissue. Its selection depends on liver anatomy and recognizable tissue planes, allowing surgeons to balance complete removal of diseased or injured segments against preservation of postoperative liver function. This balance is especially important when the remaining liver must sustain recovery.
Systematic identification of intrahepatic blood vessels and bile ducts allows each structure encountered in the transection plane to be sealed deliberately. This approach addresses two major operative hazards: bleeding from vessels and bile leakage from ducts. Controlling both helps maintain a clear, safer operative field and supports recovery after hepatic resection.
Hemostatic principles provide the framework for controlling bleeding as liver tissue is divided. Because the transection plane may contain intrahepatic blood vessels, surgeons must recognize and manage these structures rather than separating tissue without control. Effective hemostasis reduces blood loss during the operation and contributes to safer removal of the targeted liver segments.
The procedure follows a planned sequence: establish the intended resection plane, divide the liver parenchyma along that plane, identify intrahepatic blood vessels and bile ducts, and seal those structures as they are encountered. This workflow combines anatomical guidance with hemostatic control, helping surgeons remove the planned tissue while limiting bleeding and bile leakage.
Liver parenchyma transection is used in hepatectomy for tumors, in transplantation, and in selected traumatic injuries. The surgical objective varies with the indication, but the technique consistently supports controlled tissue removal or management of damaged liver while preserving as much functioning parenchyma as the planned operation allows.
In tumor surgery, controlled transection helps remove diseased liver segments while respecting the surrounding functioning parenchyma. The same emphasis on preservation matters because postoperative liver function depends on the tissue that remains. By combining a planned plane with control of vessels and bile ducts, the operation links effective disease treatment with safer functional preservation.
