TL;DR: A new scoring system to predict difficulty of various LLRs preoperatively is proposed and the calculated score well reflected difficulty.

TL;DR: Laroscopic hepatectomy avoids some of the disadvantages of open hepateCTomy and is beneficial for patient quality of life (QOL) as a minimally invasive procedure if the operative indications are appropriately based on preoperative liver function and the location and size of HCC.

TL;DR: Findings indicate that laparoscopic hepatectomy avoids the disadvantages of standard hepateCTomy for HCC in properly selected patients with cirrhosis and that its minimal invasiveness improves patients' quality of life.

TL;DR: Laparoscopic hepatectomy has become popular as a surgical treatment for liver diseases, and numerous recent studies indicate that it is safe and has advantages in selected patients, but more studies will be necessary to elucidate the optimal pneumoperitoneal pressure and the incidence of gas embolism during LH.

TL;DR: Japanese and French cohorts were used to validate the IWATE criteria by evaluating their association with the procedure‐based difficulty classification proposed by the Institut Mutualiste Montsouris and observed associations between the IwATE criteria and intraoperative and postoperative outcomes.
