IntroductionResection of perihilar cholangiocarcinoma (PHC) entails high-risk surgery with postoperative mortality reported up to 18%, even in specialized centers. The aim of this study was to compare outcomes of PHC patients who underwent associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) to patients who underwent resection without ALPPS.MethodsAll patients who underwent ALPPS for PHC were identified from the international ALPPS registry and matched controls were selected from a standard resection cohort from two centers based on future remnant liver size. Outcomes included morbidity, mortality, and overall survival.ResultsALPPS for PHC was associated with 48% (14/29) 90-day mortality. 90-day mortality was 13% in 257 patients who underwent major liver resection for PHC without ALPPS. The 29 ALPPS patients were matched to 29 patients resected without ALPPS, with similar future liver remnant volume (P = 0.480). Mortality in the matched control group was 24% (P = 0.100) and median OS was 27 months, comparted to 6 months after ALPPS (P = 0.064).DiscussionOutcomes of ALPPS for PHC appear inferior compared to standard extended resections in high-risk patients. Therefore, portal vein embolization should remain the preferred method to increase future remnant liver volume in patients with PHC. ALPPS is not recommended for PHC.
