BACKGROUND/AIM: We aimed to examine the effect of plastic biliary stenting in the treatment of common bile duct (CBD) stones. MATERIALS AND METHODS: The data of 13,034 patients in our unit who had endoscopic retrograde cholangiopancreatography (ERCP) between 2008 and 2015 were scanned retrospectively. RESULTS: A biliary stent was placed in 61 of 74 patients. While the plastic biliary stent was placed in patients, the mean stone size after the 1st ERCP was 20 mm and the bile duct size was 13 mm...

Background: Models for endoscopic retrograde cholangiopancreatography training allow practice with an expert feedback and without risks. A method to rapidly exchange the papilla can be time saving and accelerate the learning curve. Aim: To demonstrate a newly method of rapid exchange papilla in ex-vivo models to teach retrograde cholangiopancreatography advanced procedures. Methods: A new model of ex-vivo papilla was developed in order to resemble live conditions of procedures as cannulation, papilotomy or fistula-papilotomy, papiloplasty, biliary dilatation, plastic and metallic stentings...

BACKGROUND: Acute cholangitis (AC) requires the immediate initiation of antibiotic therapy in addition to treatment for biliary obstruction. Against a background of an increasing prevalence of multi-drug resistant (MDR) bacteria, the risk factors for the failure of empiric therapy must be defined. METHODS: Using a pathogen-based approach, 1764 isolates from positive bile duct cultures were retrospectively analyzed to characterize the respective pathogen spectra in two German tertiary centers...

BACKGROUND: Benign biliary stricture is a rare condition and the majority of the cases are caused by operative trauma or chronic inflammation based on various etiology. Although the initial results of endoscopic, percutaneous and surgical treatment are impressive, no comparison about long term stricture resolution is available. AIMS: The goal of this study was to compare the long term disease free survival in benign biliary strictures with various etiology after surgery, percutaneous transhepatic-and endoscopic treatment...

BACKGROUND AND AIMS: Endoscopic retrograde cholangiography (ERCP) with biliary stenting for the treatment of unresectable malignant biliary obstruction (MBO) is challenging among patients with surgically altered anatomy. Endoscopic ultrasound-guided antegrade biliary stenting (EUS-ABS) was introduced as an alternative biliary drainage method, although it has not been well studied yet. In this single-center prospective pilot study, we aimed to evaluate the feasibility and safety of EUS-ABS for MBO in patients with surgically altered anatomy...

Photodynamic therapy (PDT) is a promising therapeutic modality that involves the administration of a photosensitizer followed by local illumination with a specific wavelength of light in the presence of oxygen. PDT is minimally invasive, has high selectivity for cancer, and has good patient compliance due to the simplicity of the procedure; therefore, PDT is widely used as a palliative and salvage treatment in patients with various gastrointestinal malignancies. When used as a salvage treatment for locoregional failures after definitive chemoradiotherapy for esophageal cancer, favorable results have been reported...

PURPOSE: Biliary stents may cause artifacts in MR-images. These artifacts are caused by differences in susceptibility (artifact-1), eddy currents during read-out (artifact-2) and eddy currents due to the excitation pulse (artifact-3), which all are MRI sequence-dependent. In this study, we investigated and quantified the magnitude of these artifacts as a function of the distance from biliary stents, using a sequence-independent approach where possible. METHODS: Eight phantoms were made containing different commercial biliary stents made of nitinol, platinol, stainless steel or polyethylene...

BACKGROUND: Obstructive jaundice is a common presenting symptom among patients with pancreatic cancer. While benefits of preoperative biliary drainage have been suggested by previous studies, recent evidence has shown no significant improvements of preoperative biliary drainage on the postoperative outcome but rather an increase of complications. There is no clear consensus on whether to treat malignant obstructive jaundice with preoperative biliary drainage prior to operative intervention or to proceed directly to resection...

BACKGROUND: Fully covered self-expandable metal stents (FCSEMS) have been used successfully in the treatment of malignant and benign biliary strictures. However, stent migration is a major complication. We investigated the efficacy of anchoring FCSEMS with a 10-Fr double-pigtail plastic stent to prevent migration in patients with biliary strictures. METHODS: Between January 2012 and May 2013, 10 patients with malignant biliary strictures and one patient with a suprapapillary benign biliary stenosis were enrolled in the study...

BACKGROUND: Surgically altered gastrointestinal anatomy poses challenges for deep enteroscopy. Current overtube-assisted methods have long procedure times and utilize endoscopes with smaller working channels that preclude use of standard accessories. A through-the-scope balloon-assisted enteroscopy (TTS-BAE) device uses standard endoscopes with a large working channel to allow metallic and plastic stent insertion. We aim to determine the efficacy and safety of TTS-BAE in patients with altered surgical anatomy...

OBJECTIVES: In recent years, knowledge concerning the mechanical properties of self-expandable metallic stents (SEMS) has increased. In a previous study, we defined traction force and traction momentum and reported that these characteristics are important for optimal stent deployment. However, traction force and traction momentum were represented as relative values and were not evaluated in various conditions. The purpose of this study was to measure traction force in various situations assumed during SEMS placement...

BACKGROUND: ASGE and ESGE guidelines recommend endoscopic metal stent placement for pancreatic carcinoma patients with biliary obstruction, and whose estimated life expectancy is greater than 6 months. Because median overall survival (OS) of metastatic pancreatic adenocarcinoma until recently has been less than 6 months, plastic biliary stents were preferentially placed rather than metal due to the greater upfront cost of the latter. Recent advances in the treatment of metastatic pancreatic cancer have extended median OS beyond the 6-month range...

Portal biliopathy (PB) is defined as the presence of biliary abnormalities in patients with non-cirrhotic/non-neoplastic extrahepatic portal vein obstruction (EHPVO) and portal cavernoma (PC). The pathogenesis of PB is due to ab extrinseco compression of bile ducts by PC and/or to ischemic damage secondary to an altered biliary vascularization in EHPVO and PC. Although asymptomatic biliary abnormalities can be frequently seen by magnetic resonance cholangiopancreatography in patients with PC (77%-100%), only a part of these (5%-38%) are symptomatic...

Background. Most common bile duct (CBD) stones can be removed with standard techniques using endoscopic retrograde cholangiopancreatography (ERCP), but in some cases additional methods are needed. In this study we aimed to investigate the management of patients with difficult stones and the factors that affect the outcome of patients that have undergone periodic endobiliary stenting. Materials and Methods. Data of 1529 patients with naive papilla who had undergone ERCP with an indication of CBD stones was evaluated retrospectively...

Methods: The clinical data of 273 patients who received biliary stent drainage in Beijing Chaoyang Hospital from January 2015 to March 2016 were analyzed retrospectively. Among them, 22 patients who underwent surgical treatment were divided into two groups: 9 cases of AGC group and 13 cases of non-AGC group. The risk factors of AGC and surgical approach were analyzed...

Background and study aims Difficult cannulation is a risk factor for pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP). The double-guidewire technique (DGT) may improve cannulation success and reduce the risk of post-ERCP pancreatitis (PEP) in patients with difficult cannulation. This systematic review compared the DGT with persistent conventional cannulation or other advanced techniques in patients with difficult cannulation. Patients and Methods CENTRAL, MEDLINE, EMBASE, and CINAHL databases and DDW and UEGW abstracts up to March 2016 were searched for randomized controlled trials (RCTs) comparing DGT with persistent conventional cannulation or other advanced techniques (precut, pancreatic duct [PD] stenting)...
