AI Article Synopsis
- The study compares MRI with MRCP to ERCP for diagnosing pancreatic cancer in 52 patients.
- The results indicate that MRCP was of good quality in 88% of cases, with a combined MRI/MRCP accuracy of 88%, outperforming MRCP alone (80%) and ERCP (85%).
- The conclusion suggests that MRI with MRCP is a preferable option for suspected pancreatic cancer detection, while ERCP remains suitable for patients who can't undergo MRI or need therapeutic interventions.
Article Abstract
Purpose: To prospectively evaluate the role of MRI including MR cholangiopancreatography (MRCP) compared to endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of pancreatic cancer.
Material And Methods: ERCP and MRI including MRCP were performed in 52 patients with suspected pancreatic cancer. MRCP was obtained using a single-shot RARE technique. The results of axial images and MRCP were compared to concurrently performed ERCP examinations. The standards of reference were the surgical and pathological findings, respectively. Image quality of MRCP was assessed using a three-step-score (1 = good, 2 = fair, 3 = nondiagnostic).
Results: In 88% of the cases the MRCP was of good quality. Only in 4% was MRCP non-diagnostic. The combination of MRI and MRCP showed an overall accuracy of 88%, whereas the overall accuracies of MRCP alone and ERCP were 80%, and 85%, respectively. The positive predictive values of MRI/MRCP, MRCP alone, and ERCP were 91%, 85%, and 88%, respectively.
Conclusion: For the detection of pancreatic cancer MRI including MRCP is comparable to ERCP and can be regarded as the method of choice in patients with suspected pancreatic cancer. ERCP is the procedure of choice in patients with contraindications to MRI and in patients in whom additional therapeutic procedures are performed.

From the Department of Diagnostic Radiology, Graduate School of Medical Sciences, Kumamoto University, Kumamoto, Japan.
Objective: This preliminary study aims to assess the image quality of enhanced-resolution deep learning reconstruction (ER-DLR) in magnetic resonance cholangiopancreatography (MRCP) and compare it with non-ER-DLR MRCP images.
Methods: Our retrospective study incorporated 34 patients diagnosed with biliary and pancreatic disorders. We obtained MRCP images using a single breath-hold MRCP on a 3T MRI system.

Sump syndrome is a rare complication of biliary surgery that is now rarely seen in the era of Endoscopic Retrograde Cholangiopancreatography (ERCP). It occurs when the distal common bile duct becomes obstructed between an anastomosis from a choledochoduodenostomy (CDD) and the ampulla of Vater, forming a sump that accumulates debris. Sump syndrome should be considered as a diagnosis in patients who present with cholangitis or pancreatitis and any history of biliary diversion, regardless of the time of presentation.

This retrospective study evaluated adult patients with suspected choledocholithiasis based on labs and imaging at a single institution between 2017 and 2022 and characterized them into 1 of 3 groups based on their management pathway: (1) ERCP-first, (2) MRCP-first, or (3) surgery-first with possible intraoperative cholangiogram pending laboratory trend. Our primary outcome was hospital length of stay.

Post-surgical biliary complications increase morbidity, mortality, and healthcare utilization. Early detection and management of biliary complications is thus of great clinical importance. Even though the overall risk for biliary complications is low after laparoscopic cholecystectomy, post-cholecystectomy biliary complications are frequently encountered in clinical practice as laparoscopic cholecystectomy is the most common surgical procedure performed in the United States.
