OBJECTIVES: An increasing number of children are being diagnosed with pancreatitis and other pancreatic abnormalities. Dissemination of the information regarding existing imaging techniques and endoscopic modalities to diagnose and manage pancreatic disorders in children is sorely needed. METHODS: We conducted a review of the medical literature on the use of the following imaging and procedural modalities in pediatric pancreatology: transabdominal ultrasonography (TUS), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and endoscopic retrograde cholangiopancreatography (ERCP)...

Movement Related Cortical Potentials (MRCP) have been the subject of numerous studies. They accompany many self-initiated movements and this makes them a good candidate for incorporation in BCI paradigms. In this work we propose a novel experimental protocol involving natural controlling of a computer mouse and based on EEG recordings from 5 subjects, show that it elicits MRCP. We also show the feasibility of online detection of MRCP by implementing a classification based detection framework. Additionally, we discuss the adverse effects of causality restriction on detection performance by implementing an additional offline approach relaxing those restrictions and comparing the results...

Movement related cortical potential (MRCP), a slow cortical potential from scalp electroencephalogram (EEG), has been the used in real-time brain-computer-interface (BCI) systems designed for neurorehabilitation applications. Detecting MPCPs in real time with high accuracy is essential for a reliable BCI system in these applications. In this study, we investigated the effect of four spatial filters on MRCP detection during executed and imagined dorsiflexion of healthy participants. Our analysis indicated that, in both executed and imagined movement datasets, none of the methods investigated significantly improved trial-to-trial consistency of MRCP...

Isolated agenesis of the gallbladder is usually a rare asymptomatic anatomical variation, with an estimated incidence of 10-65 per 100,000. Females are more commonly affected (ratio 3: 1), with the disease typically presenting in the second or third decade of their life. Despite an absent gallbladder, half of the patients present with symptoms similar to biliary colic, which is poorly understood. The rarity of this condition combined with its clinical and radiological features often lead to a wrong preoperative diagnosis so that many patients undergo unnecessary operative intervention...

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is recommended for patients considered high-risk for choledocholithiasis after biochemical testing and abdominal ultrasound. Our aim was to determine whether American Society for Gastrointestinal Endoscopy (ASGE) guidelines accurately select patients where the risk of ERCP is justified. METHODS: Consecutive patients hospitalized with suspected choledocholithiasis at Sir Run Run Shaw Hospital who received biochemical testing, abdominal ultrasound, and definitive testing for choledocholithiasis (magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS), ERCP, intraoperative cholangiogram (IOC), common bile duct (CBD) exploration) were identified...

Pancreatic adenosquamous carcinoma coexisting with intraductal papillary mucinous neoplasm(IPMN)is extremely rare. We report a rare case of pancreatic adenosquamous carcinoma that developed after resection of intraductal papillary mucinous adenoma(IPMA). A 67-year-old man was suspected of having a pancreatic cystic lesion. MRCP demonstrated a cystic lesion measuring 25mm in the pancreatic tail, which had an enhanced nodule. We therefore diagnosed branch duct type IPMN of the pancreas. Although pancreatic juice cytology did not indicate malignancy, we performed laparoscope-assisted distal pancreatectomy...

INTRO: Common duct stones can be diagnosed by magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound/endoscopic retrograde cholangiopancreatography (EUS/ERCP), and intra-operative cholangiogram (IOC). In 2015, our group adopted a standard approach of preoperative EUS/ERCP followed by laparoscopic cholecystectomy for patients with an admission bilirubin over 4.0 (mg/dL). For bilirubin less than 4.0, laparoscopic cholecystectomy with IOC was the initial procedure. Post-operative EUS/ERCP with endoscopic sphincterotomy was pursued for positive IOC...

Inspissated bile syndrome (IBS) is a rare condition in which thick intraluminal bile, including bile plugs, sludge, or stones, blocks the extrahepatic bile ducts in an infant. A 5-week-old female infant was admitted for evaluation of jaundice and acholic stool. Diagnostic tests, including ultrasound sonography, magnetic resonance cholangiopancreatography, and a hepatobiliary scan, were not conclusive. Although the diagnosis was unclear, the clinical and laboratory findings improved gradually on administration of urodeoxycholic acid and lipid emulsion containing omega-3 polyunsaturated fatty acids (PUFAs) for 3 weeks...
