Abstract [en]

Background: Associating liver partition and portal vein ligation for staged hepatectomy for per-ihilar cholangiocarcinoma has been considered to be contraindicated due to the initial poor results. Given the recent reports of improved outcomes, we aimed to collect the recent expe-riences of different centers performing associating liver partition and portal vein ligation for staged hepatectomy for perihilar cholangiocarcinoma to analyze factors related to improved outcomes. Methods: This proof-of-concept study collected contemporary cases of associating liver partition and portal vein ligation for staged hepatectomy for perihilar cholangiocarcinoma and analyzed for morbidity, short and long-term survival, and factors associated with outcomes. Results: In total, 39 patients from 8 centers underwent associating liver partition and portal vein ligation for staged hepatectomy for perihilar cholangiocarcinoma from 2010 to 2020. The median preoperative future liver remnant volume was 323 mL (155-460 mL). The median future liver remnant increase was 58.7% (8.9%-264. 5%) with a median interstage interval of 13 days (6-60 days). Post-stage 1 and post-stage 2 biliary leaks occurred in 2 (7.7%) and 4 (15%) patients. Six patients (23%) after stage 1 and 6 (23%) after stage 2 experienced grade 3 or higher complica-tions. Two patients (7.7%) died within 90 days after stage 2. The 1-, 3-, and 5-year survival was 92%, 69%, and 55%, respectively. A subgroup analysis revealed poor survival for patients under-going additional vascular resection and lymph node positivity. Lymph node-negative patients showed excellent survival demonstrated by 1-, 3-, and 5-year survival of 86%, 86%, and 86%. Conclusion: This study highlights that the critical attitude toward associating liver partition and portal vein ligation for staged hepatectomy for perihilar cholangiocarcinoma needs to be revised. In selected patients with perihilar cholangiocarcinoma, associating liver partition and portal vein ligation for staged hepatectomy can achieve favorable survival that compares to the outcome of established surgical treatment strategies reported in benchmark studies for perihilar cholangiocarcinoma including 1-stage hepatectomy and liver transplantation.
