Background:
We assessed the role of mangafodipir-enhanced magnetic resonance (MR) cholangiography in the detection and location of bile duct leaks after laparoscopic cholecystectomy.
Methods:
In a prospective study, 34 patients with clinical suspicion of bile duct leak after laparoscopic cholecystectomy underwent MR imaging. Our protocol included conventional heavily T2-weighted MR cholangiography and three-dimensional T1-weighted MR cholangiography after an intravenous bolus injection of mangafodipir trisodium. All studies were performed on a 1.5-T or 1-T scanner. Contrast-enhanced MR cholangiograms were evaluated for the presence and location of bile duct leaks. Correlation was obtained in all cases with surgery (n=15), endoscopic retrograde cholangiography (n=5), percutaneous drainage (n=5), and clinical follow-up (n=9).
Results:
In 20 of 34 patients, bile duct leakage was proved by surgery, endoscopic retrograde cholangiography, or drainage. Contrast enhancement displayed the leakage in 19 of 20 patients and ruled out leaks in the other 14 patients (95% sensitivity, 100% specificity). The leak site was depicted in 14 patients and contrast-enhanced MR cholangiography successfully located the origin of the leak in 11 patients.
Conclusions:
Contrast-enhanced MR cholangiography with intravenous mangafodipir trisodium can accurately diagnose the presence and location of bile duct leaks in patients who have undergone laparoscopic cholecystectomy.
Insights
Mangafodipir-enhanced magnetic resonance cholangiography accurately detects bile duct leaks after laparoscopic cholecystectomy. This technique precisely locates the origin of leaks, improving diagnostic capabilities for post-surgical complications.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Imaging
Background:
- Laparoscopic cholecystectomy can lead to bile duct leaks.
- Accurate detection and localization of these leaks are crucial for patient management.
Purpose of the Study:
- To evaluate mangafodipir-enhanced magnetic resonance (MR) cholangiography for diagnosing bile duct leaks post-laparoscopic cholecystectomy.
- To assess the technique's accuracy in detecting and locating the origin of leaks.
Main Methods:
- Prospective study of 34 patients with suspected bile duct leaks.
- Utilized conventional and 3D T1-weighted MR cholangiography with mangafodipir trisodium.
- Correlated MR findings with surgical, endoscopic, drainage, and follow-up data.
Main Results:
- Diagnosed bile duct leaks in 20 of 34 patients.
- Mangafodipir-enhanced MR cholangiography showed 95% sensitivity and 100% specificity.
- Successfully depicted leak sites in 14 patients and located the origin in 11.
Conclusions:
- Contrast-enhanced MR cholangiography with mangafodipir trisodium is accurate for diagnosing bile duct leaks.
- The technique effectively identifies the presence and location of leaks after laparoscopic cholecystectomy.
