PURPOSE: To investigate whether the 2-devices-in-1-channel method is useful for selective biliary cannulation in patients with parapapillary diverticulum or intradiverticular papilla, where the papilla cannot be seen from the front. MATERIALS AND METHODS: Biliary cannulation using the 2-devices-in-1-channel method was performed in 28 patients who presented difficulty due to parapapillary diverticulum or intradiverticular papilla. There were 15 men and 13 women whose mean age was 68...

BACKGROUND: Chronic pancreatitis (CP) is a chronic inflammatory disease of the pancreas. This study aimed to compare the natural course of alcoholic chronic pancreatitis (ACP) and idiopathic chronic pancreatitis (ICP). METHODS: CP patients admitted to our center from January 2000 to December 2013 were enrolled. Characteristics were compared between ACP and ICP patients. Cumulative rates of diabetes mellitus (DM), steatorrhea, pancreatic stone, pancreatic pseudocyst, biliary stricture, and pancreatic cancer after the onset and the diagnosis of CP were calculated, respectively...

OBJECTIVE: Introduction: Information on chemical and phase composition of pancreoliths is limited and discrepant. There are reports, that pancreoliths are composed by calcium, phosphate, calcium carbonate or combination of calcium with fatty acids The aim of the work is studying of structural characteristics of pancreatoliths in 5 clinical cases. PATIENTS AND METHODS: Materials and methods: Morphological and crystal-chemical study of five cases of pathological biomineralization in the pancreas were conducted in the work...

Background and study aims:  Simulation-based training has become an important pillar in competence-based medicine. However, limited data are available on use of simulators in training for endoscopic retrograde cholangiopancreatography (ERCP). We aimed to determine the face and construct validity of the Boškoski-Costamagna mechanical ERCP Trainer, and to assess its didactic value, as judged by experts. Methods:  Participants were divided into four groups based on ERCP lifetime experience: novices, intermediate, experienced, and experts...

Background and study aims : Endoscopic retrograde cholangiopancreatography (ERCP) is an effective treatment for pancreaticolithiasis, including use of pancreatoscopy for intraductal electrohydraulic lithotripsy (IEHL). Pancreatoscopy is often limited by a small-caliber downstream pancreatic duct as well as an unstable pancreatoscope position within the pancreatic head. Endoscopic ultrasound-guided pancreaticogastrostomy (EUS-PG) has been developed as a method to relieve ductal obstruction when retrograde access fails...

BACKGROUND: Pancreatic ductal obstruction leading to ductal dilation and recurrent pancreatitis is uncommon in children. Treatment is dependent upon etiology but consists of decompression of the pancreatic duct (PD) proximally, if possible, by endoscopic retrograde cholangiopancreatography (ERCP) intervention or surgical decompression with pancreaticojejunal anastomosis. METHODS: After institutional review board approval, we retrospectively reviewed the records for 2 children who underwent lateral pancreaticojejunostomy for pancreatic ductal dilation...

INTRODUCTION: The significance of pancreas divisum (PD) as a risk factor for pancreatitis is controversial. We analyzed the characteristics of children with PD associated with acute recurrent or chronic pancreatitis to better understand its impact. PATIENTS AND METHODS: We compared children with or without PD in the well-phenotyped INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) cohort. Differences were analyzed using 2-sample t test or Wilcoxon rank sum test for continuous variables, Pearson χ or Fisher exact test for categorical variables...

BACKGROUND: The antigenic trigger that drives the expansion of circulating plasmablasts and CD4+ cytotoxic T cells (CD4+ CTLs) in patients with IgG4-Related Disease (IgG4-RD) is presently unknown. OBJECTIVE: We sought to sequence Ig genes from single cell clones of dominantly-expanded plasmablasts and generate recombinant human monoclonal antibodies to identify relevant antigens in IgG4-RD using mass spectrometry. METHODS: Paired heavy and light chain cDNAs from dominant plasmablast clones were expressed as monoclonal antibodies (mAbs) and used to purify antigens using immunoaffinity chromatography...

Importance: Several techniques are used for surgical treatment of gallstone disease with biliary duct calculi, but the safety and efficacy of these approaches have not been compared. Objectives: To compare the efficacy and safety of 4 surgical approaches to gallstone disease with biliary duct calculi. Data Sources: MEDLINE, Scopus, and ISI-Web of Science databases, articles published between 1950 and 2017 and searched from August 12, 2017, to September 14, 2017...

PURPOSE OF REVIEW: To provide an overview of the field of pancreatoscopy and to summarize the data informing its clinical utility. RECENT FINDINGS: Regarding the technological advance of pancreatoscopy, recent studies are the first to report the use of digital, single-operator pancreatoscopy (SpyGlass DS; Boston Scientific, Natick, MA). New data on the use of preoperative pancreatoscopy offer promising results for the potential to optimize treatment of intraductal papillary mucinous neoplasms and to differentiate between benign and malignant pancreatic strictures...

Common bile duct (CBD) stone is a relatively frequent disorder with a prevalence of 10-20% in patients with gallstones. This is also associated with serious complications, including obstructive jaundice, acute suppurative cholangitis, and acute pancreatitis. Early diagnosis and prompt treatment is the most important for managing CBD stones. According to a recent meta-analysis, endoscopic ultrasonography and magnetic resonance cholangiopancreatography have high sensitivity, specificity, and accuracy for the diagnosis of CBD stones...

BACKGROUND: Ceramide synthesis and metabolism is a promising target in cancer drug development. γ-tocotrienol (GT3), a member of the vitamin E family, orchestrates multiple effects that ensure the induction of apoptosis in both, wild-type and RAS-mutated pancreatic cancer cells. Here, we investigated whether these effects involve changes in ceramide synthesis and transport. METHODS: The effects of GT3 on the synthesis of ceramide via the de novo pathway, and the hydrolysis of sphingomyelin were analyzed by the expression levels of the enzymes serine palmitoyl transferase, ceramide synthase-6, and dihydroceramide desaturase, and acid sphingomyelinase in wild-type RAS BxPC3, and RAS-mutated MIA PaCa-2 and Panc 1 pancreatic cancer cells...

PURPOSE: To assess the usefulness of factors unique to NCCT for the prediction of ESWL outcomes in patients with pancreatic duct stones. MATERIALS AND METHODS: We retrospectively evaluated 148 patients with multiple PDS who had undergone ESWL therapy. All patients received an examination for NCCT both before and after ESWL. The following parameters were measured and recorded: patient characteristics including sex and age; NCCT parameters including mean stone length, mean stone volumes before and after ESWL, mean value of CT attenuation, standard deviation of CT attenuation, variation coefficient of CT attenuation, skin-to-stone distance, and pancreatic duct diameter; ESWL outcome indexes including stone clearance rate calculated using the formula [Formula: see text], and the number of ESWL sessions...

Background: Laparoscopic-assisted transgastric endoscopic retrograde cholangiopancreatography (LAERCP) is used for treatment in patients after Roux-en-Y gastric bypass (RYGB), where transoral access to the biliary tree is not possible. We describe our technique and experience with this procedure. Methods: Electronic medical record search was performed from September 2012 to January 2016, identifying patients who underwent LAERCP per operative records. Charts were reviewed for demographic, clinical, and outcomes data...
