The extended application of living donor liver transplantation (LDLT) has revealed the problem of graft size mismatching, potentially leading to the "small-for-size syndrome" (SFSS). SFSS is a rare dysfunction that may affect a partial liver graft, characterized by coagulopathy, cholestasis, ascites, and encephalopathy. A key role in the physiopathology of SFSS is played by portal hypertension (PHT) to which a small allograft is submitted after reperfusion, resulting in sinusoidal congestion and hemorrhage.

Article Synopsis
  • The Barcelona Clinic Liver Cancer (BCLC) staging system is crucial for treating hepatocellular carcinoma (HCC); recent updates allow for BCLC stage B patients to consider liver transplantation, while hepatectomy is now discouraged.
  • A systematic review analyzed 31 studies involving 3163 patients to compare survival rates, postoperative complications, and patient selection for liver resection versus transplantation in BCLC stage B patients.
  • Results showed that while resection had a 50-month survival and a 15-month recurrence-free period, data on transplantation was limited, with only one study reporting on it, indicating the need for more research in this area.
