Table 2. Different types of ALPPS procedures.
| Type | Technique description on stage I |
|---|---|
| Classic ALPPS (60) | Complete parenchymal transection, portal vein ligation |
| Partial ALPPS (61) | Partial parenchymal transection, portal vein ligation |
| RALPPS (62) | Radiofrequency ablation of the ideal transection line, portal vein ligation |
| Mini ALPPS (63) | Partial parenchymal transection, portal vein embolization (via inferior mesenteric vein) |
| Partial TIPE ALPPS (64) | Partial parenchymal transection, portal vein embolization (via ileocecal approach) |
| Anterior approach ALPPS (65) | Complete parenchymal transection using anterior approach, down to IVC. No liver mobilization |
| Hybrid ALPPS (66) | Complete parenchymal transection with anterior approach. PVE between two stages |
| ALTPS (67) | Application of tourniquet around the parenchymal transection line, portal vein ligation |
| Modified ALPPS with preservation of portal pedicles (68) | Complete parenchymal transection, selectively preserving portal pedicles |
| Salvage ALPPS (69) | Splitting of the liver along the main portal fissure after months from a radiological portal vein embolization |
| Left ALPPS (70) | Splitting along the main portal fissure. Left portal vein ligation |
| Right ALPPS (70) | Left lateral sectionectomy, multiple resections on the left medial, right anterior section and caudate lobe. Ligation of the posterolateral branch of the right portal vein |
