2025
Perihilar cholangiocarcinoma (pCCA) is a highly malignant and aggressive tumor, with radical resection being the only curative treatment available. With continuous advancements in laparoscopic techniques and instruments, laparoscopic radical surgery for pCCA is now considered technically safe and feasible. However, due to the high complexity of the surgery and the lack of evidence-based clinical support, laparoscopic radical surgery for type IIIb pCCA is performed only in a few large...

Source: Alomari, S., et al. Implementation of Minimally Invasive Brain Tumor Resection in Rodents for High Viability Tissue Collection. J. Vis. Exp. (2022)This video demonstrates the use of a minimally invasive resection system (MIRS) to excise tumor tissue from an anesthetized mouse implanted with a tumor. The procedure involves securing the mouse onto a stereotactic frame, reopening the previous surgical site to access the brain, and inserting a specialized cannula that utilizes suction and a...
FAQs
The planned margin creates a deliberate zone of tissue around the tumor rather than limiting removal to the visible mass. Surgeons determine its extent according to the tumor’s location, overall spread, and patterns of disease dissemination. This approach supports complete disease removal and local control, while requiring careful judgment about how much surrounding tissue can be removed safely.
En bloc removal keeps the tumor and selected surrounding tissues together as one surgical specimen. This strategy addresses the possibility that disease extends into adjacent areas or follows recognizable patterns of spread that are not fully apparent from the primary mass alone. Removing related tissues together can therefore support a more comprehensive operation and subsequent assessment.
After surgery, pathologic examination evaluates the removed tumor, surrounding tissue, and any included lymph nodes or other structures. The examination assesses the surgical margins for residual disease and characterizes findings within the specimen. These results indicate whether disease remains at the resection boundaries and can help guide decisions about additional treatment after the operation.
Planning centers on the tumor’s location, extent, and patterns of spread, because these features determine which tissues need to be included in the operative specimen. Surgeons also weigh the potential benefit of broader removal against the consequences for organ function and quality of life. The resulting plan aims to support disease control without unnecessary loss of important tissue.
Nearby lymph nodes or other structures may be removed when they are relevant to the tumor’s extent or possible pathways of spread. Including them can make the specimen more representative of the disease region and allows pathologic examination of those tissues. Their removal is therefore part of the planned surgical strategy when local anatomy and disease behavior warrant it.
Radical resection can improve local control by removing the tumor and tissues considered at risk for residual disease. The excised specimen also provides material for pathologic margin assessment and evaluation of removed tissues. Findings from that examination help clinicians determine whether further therapy should be considered, while the operation’s extent remains relevant to postoperative organ function and quality of life.
