Pancreatic stent insertion after an unintentional guidewire cannulation of the pancreatic duct during ERCP.

Introduction: the guidewire (GW) may enter the pancreatic duct during common bile duct (CBD) cannulation attempts in endoscopic retrograde cholangiopancreatography (ERCP). After GW passage into the pancreas, the most effective maneuver for CBD cannulation and pancreatitis prevention has not been determined.

Aim: to study CBD cannulation and post-ERCP pancreatitis rates when a pancreatic stent is inserted after an unintentional GW cannulation of the pancreatic duct.

Influence of baseline MELD score in the efficacy of treatment of hepatitis C with simeprevir and sofosbuvir.

Introduction: There are few published studies on predictors of response to treatment with sofosbuvir and simeprevir in HCV patients.

Objective: The objective of the study was to analyse possible predictors of response to simeprevir (SMV) and sofosbuvir (SOF) in patients infected with hepatitis C genotypes 1 or 4.

Patients And Methods: Prospective observational cohort study in 12 hospitals.

Fully covered self-expanding metal stents in the management of difficult common bile duct stones.

Background And Objectives: plastic biliary stents are often used after an ERCP session without complete common bile duct stones (CBDS) extraction. Sometimes, the volume of biliary drainage with these stents may be insufficient. We present our experience with the use of fully covered self-expanding metal stents (FCSEMS) in the setting of incomplete CBDS extraction.

Standard criteria versus Rosemont classification for EUS-diagnosis of chronic pancreatitis.

Aim: to study the possible differences in the final diagnosis of chronic pancreatitis by using standard classification described by Wiersema et al. and the new classification proposed recently by Rosemont.

Material And Methods: forty-seven patients with the diagnosis of chronic pancreatitis were included in this study.

Stenting of strictures close to the upper esophageal sphincter with the Polyflex stent.

Stent insertion in strictures in the upper cervical esophagus present special difficulties, such as patient discomfort and worry due to continuous neck globus sensation and a metallic taste. Additionally, the endoscopist needs to have great skill to properly adjust the proximal stent end. We present the experience of stenting high cervical esophageal strictures with a self-expanding plastic stent (Polyflex), in three tumoral and one postoperative benign stenosis.
