Biliary-enteric anastomoses: spectrum of findings on Gd-EOB-DTPA-enhanced MR cholangiography.
Biliary-enteric anastomosis is a common surgical procedure performed for the management of a variety of benign and malignant diseases. This procedure presents a high risk of developing complications such as anastomotic leak, hemorrhage, cholangitis, stones, stricture formation, that have been reported as ranging from 3 % to 43 %. Because the endoscopic approach of the biliary tract is generally precluded in this setting, there is clearly a role for a non-invasive imaging technique to follow up these patients and to detect the possible complications. T2-weighted MR cholangiography has been shown to be effective in the evaluation of patients with biliary-enteric anastomosis. Some of these patients may have mild duct dilatation in spite of a patent anastomosis, and stenosis should be considered only when duct dilatation is associated with narrowing of the anastomotic site. T2-weighted MRC depicts the site of biliary-enteric anastomosis, the cause of obstruction, and the status of the biliary ducts upstream. However, the disadvantages of conventional MRC are that it lacks functional information and so, differentiation between obstructive and non-obstructive dilatation of the bile ducts is often extremely difficult. T1-weighted contrast-enhanced MR cholangiography using Gd-EOB-DTPA is a recently emerging technique that is useful for delineating the anatomy of biliary-enteric anastomoses and detecting complications such as strictures, intraductal stones, and biliary leaks; besides, this technique can provide functional information that are extremely promising in the grading of biliary obstruction. We present the spectrum of findings of biliary-enteric anastomoses on Gd-EOB-DTPA-enhanced MR cholangiography focusing on the main clinical applications.

Non-invasive detection of biliary leaks using Gd-EOB-DTPA-enhanced MR cholangiography: comparison with T2-weighted MR cholangiography.
To evaluate the added role of T1-weighted (T1w) gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance cholangiography (MRC) compared with T2-weighted MRC (T2w-MRC) in the detection of biliary leaks.. Ninety-nine patients with suspected biliary complications underwent routine T2w-MRC and T1w contrast-enhanced (CE) MRC using Gd-EOB-DTPA to identify biliary leaks. Two observers reviewed the image sets separately and together. MRC findings were compared with those of surgery and percutaneous transhepatic cholangiopancreatography. The sensitivity, specificity and accuracy of the techniques in identifying biliary leaks were calculated.. Accuracy of locating biliary leaks was superior with the combination of Gd-EOB-DTPA-enhanced MRC and T2w-MRC (P < 0.05).The mean sensitivities were 79 % vs 59 %, and the mean accuracy rates were 84 % vs 58 % for combined CE-MRC and T2w-MRC vs sole T2w-MRC. Nineteen out of 21 patients with biliary-cyst communication, 90.4 %, and 12/15 patients with post-traumatic biliary extravasations, 80 %, were detected by the combination of Gd-EOB-DTPA-enhanced MRC and T2w-MRC images, P < 0.05.. Gd-EOB-DTPA-enhanced MRC yields information that complements T2w-MRC findings and improves the identification and localisation of the bile extravasations (84 % accuracy, 100 % specificity, P < 0.05). We recommend Gd-EOB-DTPA-enhanced MRC in addition to T2w-MRC to increase the preoperative accuracy of identifying and locating extravasations of bile.. • Magnetic resonance cholangiography (MRC) does not always detect bile leakage and cysto-biliary communications. • Gd-EOB-DTPA-enhanced MRC helps by demonstrating extravasation of contrast material into fluid collections. • Gd-EOB-DTPA-enhanced MRC also demonstrates the leakage site and bile duct injury type. • Combined Gd-EOB-DTPA-enhanced and T2w-MRC can provide comprehensive information about biliary system. • Gd-EOB-DTPA-enhanced MRC is non-invasive and does not use ionising radiation.

Detection of active bile leak with Gd-EOB-DTPA enhanced MR cholangiography: comparison of 20-25 min delayed and 60-180 min delayed images.
The purpose of this study was to assess the value of contrast-enhanced magnetic resonance cholangiography (MRC) performed in different time delays after injection of gadoxetic acid disodium (Gd-EOB-DTPA) for the diagnosis of active bile leak.. This retrospective analysis included Gd-EOB-DTPA enhanced MR images of 34 patients suspected of bile leak. Images were acquired 20-25 min after Gd-EOB-DTPA injection. If there was inadequate contrast in the bile ducts then delayed images after 60-90 min and 150-180 min were obtained. Results were correlated with intraoperative findings, ERCP results, clinical data, laboratory tests, and follow-up examinations.. Gd-EOB-DTPA enhanced MRC yielded an overall sensitivity of 96.4%, specificity of 100% and accuracy of 97.1% for the diagnosis of an active bile leak. The sensitivity of 20-25 min delayed MR images was 42.9%, of combined 20-25 min and 60-90 min delayed images was 92.9% and of combined 20-25 min, 60-90 min and 150-180 min delayed images was 96.4%.. Gd-EOB-DTPA enhanced MRC utilizing delayed phase images was effective for detecting the presence and location of active bile leaks. The images acquired 60-180 min post-injection enabled identification of bile leaks even in patients with a dilated biliary system or moderate liver dysfunction.
