Response to Letter “Systematic Grading of Morbidity After Living Donation for Liver Transplantation”
published online 01 October 2009.
One of the primary aims of the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) is the analysis of short- and long-term outcomes in living liver donors. We have adopted the use of the severity grading system for complications described by Clavien in 1994 and still believe it is the best grading system available to classify donor complications. The A2ALL report on the complication rates and grading of complications was published in this journal in 2008.1
