Abstract

Purpose: Pancreaticobiliary maljunction (PBM) is routinely assessed by intraoperative cholangiography (IOC), whereas accompanying abnormalities in the hepatic artery are assessed by preoperative contrast multi-slice computed tomography (MSCT). We evaluated the efficiency of performing one-stop preoperative magnetic resonance imaging (MRI) for delineating the anatomy of the pancreaticobiliary junction and the hepatic artery.

Methods: The subjects of this prospective analysis were children who underwent Roux-en-Y surgery for PBM in our institution during a recent 3-year period. Preoperative one-stop MRI was conducted using 3.0-T MRI. The efficiency of one-stop MRI was compared with that of IOC for assessing the bile duct, and with contrast MSCT for assessing the blood vessels.

Results: Sixty-five children underwent one-stop preoperative MRI, which had a 100% concordance rate, versus IOC for assessing the bile duct type. Protein plugs or cholelithiasis were identified by IOC in 8 children and by one-stop MRI in 45 children (P = 0.0233). Cholangitis was not identified by IOC in any children but it was identified by one-stop MRI in 29 children. MSCT was also performed in 46 children and revealed a variant hepatic artery in 9 and cholangitis in 21. One-stop MRI had a 100% concordance rate versus MSCT.

Conclusion: Preoperative one-stop MRI accurately delineates the bile duct anatomy as well as the hepatic artery, cholangitis, and protein plugs in children with PBM.
