Endoscopy is the first-line therapy for most post-liver transplantation anastomotic biliary strictures. Passage of a guidewire through the stricture is done under fluoroscopic guidance. Although anastomotic biliary strictures are usually short, they can be tight, fibrotic, and angulated, sometimes not allowing guidewire passage. Additional interventions (percutaneous transhepatic cholangiograph...

Background/Aim: Difficult urethral catheterization (DUC) is a frequent urological emergency in daily practice. Anticoagulant and antiaggregant drugs, included the treatment protocols for COVID-19, tend to increase risk of possible complications alternative interventions, such as cystoscopy suprapubic percutaneous cystostomy. Therefore, less invasive method needed patients with DUC. This study a...

Endoscopic ultrasound (EUS)-guided biliary drainage via either gastrohepatostomy or choledochoduodenostomy are accepted and widespread procedures when endoscopic retrograde cholangiopancreatography (ERCP) fails. EUS guidewire insertion through a 19-G needle into a dilated biliary system is usually a straightforward maneuver. The drainage difficulty begins when the enterobiliary tract has to be ...

Myocardial fractional flow reserve (FFR(myo)) and coronary flow reserve (CFR), measured with guidewire, and quantitative angiography (QA) are widely used in combination to distinguish ischemic from non-ischemic coronary stenoses. Recent studies have shown that simultaneous measurements of FFR(myo) and CFR are recommended to dissociate conduit epicardial coronary stenoses from distal resistance ...

A 75-year-old woman was admitted for the extraction of an esophageal fully covered metal stent (upper esophageal sphincter stent [80×20mm]; LeufenMedical, Berlin, Germany). The stent had been implanted 5 weeks earlier to treat an esophageal perforation sustained during bougienage of a benign proximal esophageal stenosis. The location of the stent was distal to the stricture, so that only a tran...

BACKGROUND Central venous catheters (CVC) removal and reinsertion of a new CVC in the setting of central line associated bloodstream infections (CLABSI) is not always possible in septic patients. The purpose of this study was to evaluate the outcome of patients with Staphylococcus aureus-CLABSI (SA-CLABSI) who had their CVCs exchanged over guidewire for minocycline/rifampin-coated (M/R)-CVC wit...

Endoscopic biliary stent placement is a well-established technique for various indications including biliary drainage. However, it has been shown that approximately 5% of plastic stents placed in the biliary tract migrate proximally [1]. Endoscopic retrieval of proximally migrated biliary stents is technically challenging and occasionally unsuccessful. Several techniques for retrieving proximal...

BACKGROUND The severity of epicardial coronary stenosis can be assessed by invasive measurements of trans-stenotic pressure drop and flow. A pressure or flow sensor-tipped guidewire inserted across the coronary stenosis causes an overestimation in true trans-stenotic pressure drop and reduction in coronary flow. This may mask the true severity of coronary stenosis. In order to unmask the true s...
