Background
Laparoscopic liver resection (LLR) is now widely performed in treating primary liver cancer (PLC) and yields equal long-term and superior short-term outcomes to those of open liver resection (OLR). The optimal surgical approach for resectable PLC (rPLC) remains controversial. Herein, we aimed to develop a nomogram to determine the most appropriate resection approach for the individual patient.
Methods
Patients with rPLC who underwent hepatectomy from January 2013 to December 2018 were reviewed. Prediction model for risky surgery during LLR was constructed.
Results
A total of 900 patients in the LLR cohort and 423 patients in the OLR cohort were included. A history of previous antitumor treatment, tumor diameter, tumor location and resection extent were independently associated with risky surgery of LLR. The nomogram which was constructed based on these risk factors demonstrated good accuracy in predicting risky surgery with a C index of 0.83 in the development cohort and of 0.76 in the validation cohort. Patients were stratified into high-, medium- or low-risk levels for receiving LLR if the calculated score was more than 0.8, between 0.2 and 0.8 or less than 0.2, respectively. High-risk patients who underwent LLR had more blood loss (441 ml to 417 ml) and a longer surgery time (183 min to 150 min) than those who received OLR.
Conclusions
Patients classified into the high-risk level for LLR instead undergo OLR to reduce surgical risks and complications and patients classified into the low-risk level undergo LLR to maximize the advantages of minimally invasive surgery.
