概要	OBJECTIVE:The purpose of this study is to compare technical success and complications of percutaneous transhepatic cholangiography (PTC) and percutaneous transhepatic biliary drainage (PTBD) between patients with and without transplanted liver.MATERIALS AND METHODS:Between 2007 and 2011, 89 PTCs, including 34 PTBDs, in 87 patients with transplanted liver were attempted, and 131 PTCs, including 118 PTBDs, in 126 patients without transplanted liver were attempted. Technical success, diameteMATERIALS AND METHODS:rs of the bile ducts, fluoroscopy time, and complications were statistically compared between the two groups.RESULTS:The technical success rate of PTC for transplanted liver was significantly lower than that for nontransplanted liver (88.8% vs 98.5%; p = 0.004). Consequently, the technical success rate of PTBD for transplanted liver was also significantly lower than that for nontransplanted liver (75.0% vs 95.8%; pRESULTS:<RESULTS:0.001). The average diameters of the first branches and second branches of the bile ducts of transplanted liver were significantly smaller than those of nontransplanted liver (5.8 ± 3.4 mm vs 8.7 ± 3.9 mm for the first branches [pRESULTS:<RESULTS:0.001RESULTS:]RESULTS:; and 3.7 ± 1.7 mm vs 5.8 ± 2.4 mm for the second branches [pRESULTS:<RESULTS:0.001RESULTS:]RESULTS:). No significant difference of fluoroscopy time of unilateral successful PTBD was observed (21.8 ± 11.7 vs 19.3 ± 12.9 min; p = 0.372), and no significant difference of overall complication rates was observed (8.0% vs 8.7%; p = 1.000) between transplanted and nontransplanted liver.CONCLUSION:The technical success rates of PTC and PTBD for transplanted liver are slightly lower than those for nontransplanted liver because the bile ducts are smaller. There is no significant difference in complication rate.
