ARTICLE HIGHLIGHTS
Research background
The preoperative regimen of indocyanine green (ICG) administration in laparoscopic hepatectomy was still controversial. Factors associated with tumor fluorescence staining effect were unclear.
Research motivation
Establish a novel laboratory scoring system to screen specifical patients who need ICG dose adjustment.
Research objectives
Establish a risk model that can predict the effect of liver ICG preoperative staining through clinical indicators, and reduce the probability of ICG staining failure events.
Research methods
All enrolled patients received 5 mg ICG 24 h before laparoscopic hepatectomy, then investigate the predictive indicators of ICG fluorescence characteristics and established a laboratory risk model to identify individuals at high risk for high liver background fluorescence.
Research results
Pre-operative aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, adenosine deaminase, and lactate dehydrogenase were positively associated with fluorescence intensity of background liver (FI-LB) and pre-operative red blood cell, cholinesterase, and were negatively associated with FI-LB. Total laboratory risk score (TLRS) was calculated according to receiver operating characteristic (ROC) curve [area under the ROC curve (AUC) = 0.848, sensitivity = 0.773, specificity = 0.885]. When TLRS was greater than 6.5, the liver clearance ability of ICG was considered as poor.
Research conclusions
Common preoperative laboratory blood parameters can be used to predict liver ICG clearance. The established risk prediction model helps to identify individuals who may be at risk of fluorescent staining failure. Surgeons can calculate the risk value of high liver background fluorescence intensity based on relevant blood indicators, so as to adjust the dose and time of ICG before operation, and finally obtain better liver fluorescence staining.
Research perspectives
More effective clinical indicators (including preoperative ultrasound or radiographic examination characteristics, blood tumor indicators, etc.) are expected to be added to the model for predicting liver ICG fluorescence staining, further improving the accuracy of the model, and thus obtaining greater clinical application value.
