Caudate lobe-based minimally invasive anatomic hepatectomy: a retrospective study

Abstract

Abstract Background: Anatomic hepatectomy has become a crucial surgical procedure in the liver section. The function and role of the caudate lobe in anatomic hepatectomy remain unclear. Thus, this study aimed to summarize the efficiency of caudate lobe-based anatomic hepatectomy. Methods: Three hundred thirty-one cases were enrolled in this retrospective study. They underwent minimally invasive hepatectomy based on caudate lobe-based anatomic hepatectomy theory. The operation time, blood loss, postoperative CRP, and hospital duration were collected for further analysis. Results: The mean length of G1L was longer than that of G1C. The length of G1C or G1L was negatively correlated with clinical outcomes (bleeding volume, operation time, postoperative CRP, and hospital duration) and the occurrence of operation-associated complications. Further subgroup analysis showed that theclinical outcomes (postoperative CRP and bleeding volume) of patients who underwent right hepatectomy were negatively associated with the length of the G1C, and the length of the G1L wasconnected to the clinical outcome of patients after left hepatectomy. Conclusion: Based on the outcomes of 331 patientsundergoing hepatectomy, caudate lobe-based anatomic hepatectomy theory was feasible and efficient for anatomic liver sections.
