Associating liver partition and portal vein ligation for staged hepatectomy in the treatment of colorectal cancer liver metastases

Table 1 Key modalities of the associating liver partition and portal vein ligation for staged hepatectomy technique

ALPPS strategies	Technical points
Classical ALPPS	Right portal vein ligation and right trisectionectomy
Rescue ALPPS	Failure of PVE with subsequent ALPPS
Laparoscopic ALPPS	Laparoscopy for stage 1 or both stages 1 and 2
PVE ALPPS	The intentional use of PVE as part of the first stage is stated by using PVE-ALPPS
Partial ALPPS	Transection at least 50% of the future transection plane at stage 1
Left ALPPS	Left portal vein ligation, left trisectionectomy
Tourniquet ALPPS	Tourniquet in the umbilical fissure and portal vein occlusion
Radiofrequency ALPPS	Radio-frequency-assisted liver partition
Microwave ALPPS	Microwave transection of the liver
Monosegment ALPPS	Extending hepatectomy, only sparing a single or adjacent segment

ALPPS: Associating liver partition and portal vein ligation for staged hepatectomy; PVE: Portal vein embolization.
