title: Value of contrast-enhanced magnetic resonance cholangiography in patients undergoing laparoscopic cholecystectomy.
abstract: Laparoscopic cholecystectomy (LC) is the preferred treatment of symptomatic gallstone disease. Biliary injury during LC is still a serious problem. Knowledge of anatomic detail is important for not encountering the injury. Magnetic resonance cholangiography (MRC) is a noninvasive method for imaging the biliary ducts. However, MRC has many drawbacks such as not showing anatomic structures in detail and respiratory motion. In this study, contrast-enhanced MRC is used to show cystic ducts that are not seen by MRC. Reasons for patient referral for MRC and contrast-enhanced MRC included suspicion of cholecystolithiasis, adenomyomatosis, and gallbladder polyp. Our results show that routine MRC revealed cystic ducts in 38 patients (77.5%) and contrast-enhanced MRC in 46 patients (93.8%). Intraoperative cholangiography (IOC) was taken as gold standard for all patients. We found that contrast-enhanced MRC can provide a useful supplement to MRC in patients with nonvisualized cystic ducts by MRC. To our knowledge, this is the first study of visualization of cystic duct in patients undergoing LC depicted by both MRC and contrast-enhanced MRC.
