AIM:To evaluate the diagnostic value of different indirect methods like biochemical parameters, ultrasound (US) analysis, CT-scan and MRI/MRCP in comparison with endoscopic retrograde cholangiography (ERC), for diagnosis of biliary complications after liver transplantation. METHODS:In 75 patients after liver transplantation, who received ERC due to suspected biliary complications, the result of the cholangiography was compared to the results of indirect imaging methods performed prior to ERC. The cholangiography showed no biliary stenosis (NoST) in 25 patients, AST in 27 and ITBL in 23 patients. RESULTS:Biliary congestion as a result of AST was detected with a sensitivity of 68.4% in US analysis (specificity 91%), of 71% in MRI (specificity 25%) and of 40% in CT (specificity 57.1%). In ITBL, biliary congestion was detected with a sensitivity of 58.8% in the US, 88.9% in MRI and of 83.3% in CT. However, as anastomotic or ischemic stenoses were the underlying cause of biliary congestion, the sensitivity of detection was very low. In MRI detected the dominant stenosis at a correct localization in 22% and CT in 10%, while US failed completely. The biochemical parameters, showed no significant difference in bilirubin (median 5.7; 4,1; 2.5 mg/dL), alkaline phosphatase (median 360; 339; 527 U/L) or gamma glutamyl transferase (median 277; 220; 239 U/L) levels between NoST, AST and ITBL. CONCLUSION:Our data confirm that indirect imaging methods to date cannot replace direct cholangiography for diagnosis of post transplant biliary stenoses. However MRI may have the potential to complement or precede imaging by cholangiography. Optimized MRCP-processing might further improve the diagnostic impact of this method.

“…The phenomenon of limited dilatation of donor ducts further underestimates the diagnosis of strictures on MRCP imaging. Specific criteria have been proposed for diagnosis on MRCP imaging [30] . The variables that need to be studied in MRCP include type of anastomosis, length of stricture, length of common stump proximal to the anastomosis and differential diameters of recipient and donor ducts, etc.…”

“…Other causes include retained stones within the graft or stones formed secondary to bile stasis from biliary strictures. Biliary stones are well depicted with US and MR imaging (Kok et al, 1996;Laghi et al, 1999;Linhares et al, 2004). Interventional procedures may be useful for obviating surgery in these patients .…”
