En Bloc Resection of the Liver and Pancreas With a "Non-touch" Technique Followed by Liver Transplantation to Improve the Overall Survival in Patients With Non-resectable Hilar Cholangiocarcinoma Beyond the Mayo Clinic Transplant Criteria

Surgery for hilar cholangiocarcinoma (phCCA) remains a significant challenge. The minority of patients who are eligible for resection are exposed to high procedure-related morbidity and mortality, and despite apparent R0 resection, cancer recurrence is common. The benefit of R1 resection compared to the best palliative chemotherapy has been questioned. The concept of extended surgery to achieve better radicality is controversial and in many instances, associated with higher procedure-related risk and unclarified oncological benefit. For unresectable patients, liver transplantation, per the Mayo protocol, remains the only alternative for a few patients. Optimal staging pre- and intraoperatively is problematic since only the local biliary ductal involvement and, to a certain extent, lymph node dissemination can be reasonably correctly assessed. The reliability and validity of the intraoperative frozen section have been questioned. Furthermore, microscopic tumor cell affection leading to recurrent disease has been found in 16% of presumed N0 lymph nodes when analyzed by immunohistochemistry, and patients with nodal micrometastasis showed the same dismal survival as those with positive nodes on regular pathology (pN1). Taken together, there is a lack of good surgical options for patients with marginally or unresectable phCCA that do not satisfy current criteria for liver transplantation. The practical problem in the current surgical techniques for hilar cholangiocarcinoma, par…
