Main factors involved in the choice of the bariatric procedure in the setting of liver transplantation
| Factors to consider | SG | RYGB |
| Bleeding risk of bleeding1 | Increased | Low |
| Endoscopic access to the biliary tree | Conserved | Impossible |
| Risk of portal vein thrombosis | Increased | Not affected |
| Risk of bariatric surgery induced liver failure | Absent | Low |
| Absorption of immunosuppressive drugs | Poorly affected | Decreased |
| Etiology of liver cirrhosis (NASH vs others) | Effective | Very Effective |

Consider measuring of portal pressure and use of transjugular intrahepatic portosystemic shunt in case of bariatric surgery before liver transplantation. SG: Sleeve gastrectomy; RYGP: Roux-en-Y gastric bypass; NASH: Non-alcoholic steato hepatitis.
