Newest firstBackground/objectives Post-cholecystectomy syndrome (PCS) remains diagnostically challenging due to overlapping biliary and non-biliary causes. This study aimed to evaluate whether common bile duct (CBD) diameter measured by MRCP can serve as a practical triage parameter in symptomatic PCS patients and to define a data-supported threshold for predicting clinically relevant biliary pathology. Secondary objectives i…
Open article record in new tab ↗Purpose This study aims to detect common bile duct (CBD) dilatation using deep learning methods from artificial intelligence algorithms. Methods To create a convolutional neural network (CNN) model, 77 magnetic resonance cholangiopancreatography (MRCP) images without CBD dilatation and 70 MRCP images with CBD dilatation were used. The system was developed using coronal maximum intensity projection reformatted 3D-M…
Introduction The American Society for Gastrointestinal Endoscopy (ASGE) guidelines for common bile duct (CBD) stone management were created to risk stratify patients into low, intermediate, and high-risk groups to optimize interventions. Low-risk patients typically proceed to cholecystectomy with or without Intra-operative cholangiogram (IOC) whereas high-risk patients typically proceed to common duct clearance. T…
Open article record in new tab ↗Objectives PSC strictures are routinely diagnosed on T2-MRCP as dominant- (DS) or high-grade stricture (HGS). However, high inter-observer variability limits their utility. We introduce the "potential functional stricture" (PFS) on T1-weighted hepatobiliary-phase images of gadoxetic acid-enhanced MR cholangiography (T1-MRC) to assess inter-reader agreement on diagnosis, location, and prognostic value of PFS on T1-…
Background Duplication of the extrahepatic bile duct (DCBD) is an extremely rare congenital anomaly of the biliary system. There are five types of DCBD according to the latest classification. Among them, Type V is characterized by single drainage of the extrahepatic bile ducts. Reports on DCBD Type V are scarce. Case summary A 77-year-old woman presented with recurrent epigastric pain but without fever or chills.…
Open article record in new tab ↗Background Biliary intraepithelial neoplasia (BilIN) is often distinguished by what it is not: the precancerous lesions are not mass-forming, are not the cause of bile duct obstruction, and are small enough (less than 5 mm long) to evade detection by the naked eye. Here, we describe an atypical case of BilIN resembling cholangiocarcinoma (CC) that was large enough to be identified by diagnostic imaging and present…
Background Common bile duct (CBD) stones are common. However, they are known to pass spontaneously, which obviates the need for ERCP. Aim The aim of this study is to identify specific predictors for spontaneous passage of CBD stones. Methods Data was retrospectively collected for all patients who were hospitalized with clinical, laboratory, or ultrasonographic evidence of choledocholithiasis and who underwent magn…
Background The genesis of the "complex type" classification of pancreaticobiliary maljunction (PBM) is unclear, and the pancreaticobiliary anatomy is also varied according to each case. We encountered a patient with PBM and incomplete pancreatic divisum (PD). We herein discussed about the embryological etiology of pancreaticobiliary system predicted from PBM with incomplete PD. Case presentation A 67-year-old man…
Open article record in new tab ↗Background Laparoscopic cholecystectomy (LC) is the standard treatment for gallbladder diseases. Intraoperative cholangiography (IOC) can reduce biliary complications of LC; however, with the emergence of magnetic resonance cholangiopancreatography (MRCP), IOC nowadays is faced with unprecedented challenge. The purpose of this study is to evaluate whether preoperative MRCP can safely replace IOC during elective LC…
Background The diagnosis of associated choledocholithiasis prior to cholecystectomy for patients with gallstones is important for the surgical decision and treatment efficacy. However, whether ultrasound is sufficient for preoperative diagnosis of choledocholithiasis remains controversial, with different opinions on whether routine magnetic resonance cholangiopancreatography (MRCP) is needed to detect the possible…
Open article record in new tab ↗Rationale Obstructive jaundice can raise problems to diagnostic imaging. The radiologist must choose the most appropriate examination that delivers the most important diagnostic information because the differences between a lithiasic obstruction and a tumoral one are vital. This information helps the surgeon speed up the process of decision-making, because the treatment may be very different in relation to the nat…
Fascioliasis is a zoonotic infection caused by Fasciola hepatica or Fasciola gigantica. We report an 87-year-old Korean male patient with postprandial abdominal pain and discomfort due to F. hepatica infection who was diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP) with extraction of 2 worms. At his first visit to the hospital, a gallbladder stone was suspected. CT and magnetic retro…
Duodenal diverticula are detected in up to 27% of patients undergoing upper gastrointestinal tract evaluation with periampullary diverticula (PAD) being the most common type. Although PAD usually do not cause symptoms, it can serve as a source of obstructive jaundice even when choledocholithiasis or tumor is not present. This duodenal diverticulum obstructive jaundice syndrome is called Lemmel's syndrome. An 81-yr…
Purpose There are risks of common bile duct (CBD) stones in acute cholecystitis, and there is a move among surgeons to identify choledocholithiasis before surgery. Magnetic resonance cholangiopancreaticography (MRCP) has the potential to accurately detect choledocholithiasis in patients with acute cholecystitis. The aim of this study was to evaluate the predictive values of MRCP and elevated biochemical predictors…
Open article record in new tab ↗The diagnostic accuracy of percutaneous transhepatic cholangioscopy (PTCS) was compared to that of three radiologic modalities in distal common bile duct (CBD) strictures for the evaluation of clinical application. Ninety-five patients who underwent PTCS for the evaluation of distal CBD strictures (35 malignant and 60 benign) whose masses were not obvious from radiologic imagings were included. Confirmative diagno…
