Letter to the editor: Short-term data on machine perfusion should be extrapolated with caution

I read with great interest the publication by de Goeij et al titled "Hypothermic oxygenated machine perfusion protects from cholangiopathy in DCD liver transplantation" (1). I commend the authors on their excellent summary of an emerging field in transplant hepatology, however I advise them and the readers to exercise caution when extrapolating these results to long-term clinical outcomes.
