Comparison between traditional diagnostic criteria with the “unpaired hepatic artery” method for diagnosis of ductopenia

Criteria
 % Diagnostic biopsies (group 2)
 P value (versus UHA method)
1. Unpaired hepatic artery method criteria 59.4%
Traditional Method:
2. <50% of all PTs containing at least one BD (no adequacy criteria observed) 43.7% P=0.31
3. <50% of PTs containing at least one BD (only complete PTs considered) 31.2% P=0.04
5. <50% of all PTs containing at least one BD ( at least 10 PTs present) 21.8% P=0.005
4. <50% of all PTs containing at least one BD (at least 5 complete PTs present) 15.6% P<0.001

Abbreviations: UHA, unpaired hepatic artery; PT, portal tract; BD, bile duct.
