AIM To investigate the relationship between pathological oropharyngeal (OP) acid exposure and esophageal motility in patients with extra-esophageal syndromes. METHODS In this prospective study we enrolled consecutive outpatients with extra-esophageal symptoms suspected to be related to gastroesophageal reflux disease (GERD). We enrolled only patients with(More)
BACKGROUND The guidewire biliary cannulation (GWC) technique may increase the cannulation rate and decrease the risk for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The aim of our multicenter prospective randomized controlled trial was to determine if the use of an atraumatic loop-tip guidewire reduces the rate of post-ERCP(More)
INTRODUCTION Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely used to diagnose pancreatic malignancies. Different EUS-FNA techniques have been described to improve sample quality. Recently, a new technique, using capillarity, has been proposed. AIM To assess the quality of cytological samples, comparing two different FNA techniques,(More)
BACKGROUND 24-hour esophageal pH-impedance (pH-MII) is not totally reliable for laryngopharyngeal reflux (LPR). Oropharyngeal (OP) pH-monitoring with the Dx-pH probe may detect LPR better. The correlation between these two techniques is not thoroughly established. Aim of this study is to examine the correlation between OP pH-metry and esophageal pH-MII(More)
Esophageal manometry (EM) and ambulatory 24-hour esophageal pH-metry (EP) are techniques employed in the management of patients with gastroesophageal reflux disease (GERD). For these examinations, two consecutive probes must be placed nasally. To evaluate the introduction-time (IT) and patient tolerance (PT) during introduction of the EP probe after EM with(More)
56 patients with large CBD or intrahepatic stones underwent endoscopic and/or percutaneous treatment followed by extracorporeal shock wave lithotripsy. Percutaneous access to the biliary tract was chosen when an endoscopic approach was not possible (hepaticojejunostomy in 5 patients, 1 juxtapapillary diverticulum and 1 inflammatory bile duct stricture).(More)
