Abstrakt: Background: The prognosis of Klatskin tumors is poor, and radical surgery with disease-free surgical margins (R0) represents the treatment capable of ensuring the best long-term outcomes. In patients with Klatskin tumors, both right hepatectomy and left hepatectomy might achieve R0 surgical margins. This systematic review concentrated on a comparative investigation between left hepatectomy and right hepatectomy, aiming to furnish clinical evidence and to aid in surgical decision-making for Klatskin tumor depending on its spread within the bile duct tree.
Methods: The eligible articles in the study were obtained from PubMed, Medline, and Scopus databases, following the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis, and they were categorized according to the type of Klatskin tumor treated with right hepatectomy or left hepatectomy. The studies that analyzed the outcomes related to the 2 surgical techniques without focusing on the type of Klatskin tumor were included in a separate paragraph and table.
Results: In total, 21 studies were included. Four studies reported outcomes of right hepatectomy or left hepatectomy for Klatskin type I/II tumor, 2 for Klatskin type II/IV tumor, 2 for Klatskin type III tumor, and 2 for Klatskin type IV. Eleven studies included the outcomes of right hepatectomy and left hepatectomy for hilar cholangiocarcinoma without specifying the type of Klatskin tumor. Although long-term oncologic outcomes seem comparable between right hepatectomy and left hepatectomy when achieving R0 resection for Klatskin type III/IV tumors, there may exist a marginal oncologic edge and reduced complication rates favoring left hepatectomy in individuals with Klatskin type I/II tumors.
Discussion: Right hepatectomy traditionally has played a central role in treating Klatskin tumor, but recent studies have questioned its oncologic efficacy and surgical risks. Currently, there is a lack of evidence regarding the ideal surgical approach for each type of Klatskin tumor, and surgical strategy relies heavily on the individual surgeon's experience and technical skills. The management of Klatskin tumors necessitates specialized hepatobiliary surgical centers capable of conducting major hepatectomy with thorough lymphadenectomy, biliary, and vascular reconstructions. There is a need for studies with larger sample sizes to achieve a wide consensus about the superiority of one surgical technique over the other in cases in which both right hepatectomy and left hepatectomy can achieve an R0 margin.
