Table 1 Key modalities of the associating liver partition and portal vein ligation for staged hepatectomy technique
ALPPS strategies
Technical points
Classical ALPPSRight portal vein ligation and right trisectionectomy
Rescue ALPPSFailure of PVE with subsequent ALPPS
Laparoscopic ALPPSLaparoscopy for stage 1 or both stages 1 and 2
PVE ALPPSThe intentional use of PVE as part of the first stage is stated by using PVE-ALPPS
Partial ALPPSTransection at least 50% of the future transection plane at stage 1
Left ALPPSLeft portal vein ligation, left trisectionectomy
Tourniquet ALPPSTourniquet in the umbilical fissure and portal vein occlusion
Radiofrequency ALPPSRadio-frequency-assisted liver partition
Microwave ALPPSMicrowave transection of the liver
Monosegment ALPPSExtending hepatectomy, only sparing a single or adjacent segment
