American Society of Anesthesiologists classification, preoperative anxiety, solid food fasting time, clear liquid fasting time, indwelling catheter, and pain level upon awakening are key predictors of EA in patients undergoing laparoscopic hernia surgery with total intravenous anesthesia and caudal block anesthesia. The nomogram predicts EA with an area under the receiver operating characteristic curve (AUC) of 0.947, a sensitivity of 0.917, and a specificity of 0.877, whereas the random forest model has an AUC of 0.923, a sensitivity of 0.912, and a specificity of 0.877.

While radiofrequency ablation (RFA) has shown safety and effectiveness in treating HCC, with lower mortality rates and shorter hospital stays, its high recurrence rate remains a significant impediment. Consequently, achieving improved survival solely through RFA is challenging, particularly in retrospective studies with inherent biases. Ultrasound is commonly used for guiding percutaneous RFA, but its low contrast can lead to missed tumors and the risk of HCC recurrence. To enhance the efficiency of ultrasound-guided percutaneous RFA, various techniques such as artificial ascites and contrast-enhanced ultrasound have been developed to facilitate complete tumor ablation. Minimally invasive surgery (MIS) offers advantages over open surgery and has gained traction in various surgical fields. Recent studies suggest that laparoscopic intraoperative RFA (IORFA) may be more effective than percutaneous RFA in terms of survival for HCC patients unsuitable for surgery, highlighting its significance. Therefore, combining MIS-IORFA with these enhanced percutaneous RFA techniques may hold greater significance for HCC treatment using the MIS-IORFA approach.
