NORMAL VALUES OF ESOPHAGEAL 24-HOUR IMPEDANCE-PH AMBULATORY IN AN ARGENTINE COHORT OF HEALTHY VOLUNTEERS.

Background: There are no data of reference values on 24-hour multichannel intraluminal impedance and pH (pH-MII) monitoring in Argentinian populations.

Objective: Our aim was to obtain the normal values of pH-MII variables among healthy asymptomatic volunteers in a metropolitan Health Care Center of Argentina, and to compare them with data already published from other regions around the world.

Methods: A cross-sectional study was undertaken in a tertiary referral center in Buenos Aires.

Insertion of fully covered self-expanding metal stents in benign biliary diseases.

Introduction: Benign biliary diseases are traditionally treated using plastic stents. However, fully covered self-expanding metal stents are currently gaining acceptance for the treatment of these pathologies.

Objective: To assess the effectiveness and complications associated with the placement of temporary endoscopic fully covered self-expanding metal stents for the treatment of benign biliary diseases.

Post-ERCP pancreatitis: early precut or pancreatic duct stent? A multicenter, randomized-controlled trial and cost-effectiveness analysis.

Background: Pancreatitis is the most frequent complication due to ERCP. Pancreatic duct stent placement has been described as a preventive measure. There is also evidence pointing towards the preventive effect that early precut may provide.

Early precut is as efficient as pancreatic stent in preventing post-ERCP pancreatitis in high-risk subjects - A randomized study.

Background: The most common adverse event of endoscopic retrograde cholangiopancreatography is pancreatitis. Precut sphincterotomy has been regarded as a risk factor. Some authors have stated that early precut may actually reduce post-ERCP pancreatitis risk.

[Endoscopic ultrasound-guided choledocho-duodenostomy in advanced pancreatic cancer with duodenal obstruction].

Endoscopic retrograde cholangiopancreatography (ERCP) is considered the first-approach for biliary drainage. In cases of ERCP failure, patients are usually referred for percutaneous transhepatic biliary drainage or surgical biliary bypass. In the last decade, the indications of endoscopic ultrasound (EUS) in the management of patients with pancreatic cancer have increased, and numerous cases of EUS-guided biliary drainage have been reported in patients with failures during the ERCP.

[Hilar bile duct tumors: Endoscopic or percutaneous drainage? A prospective analysis].

Background And Objective: Both the endoscopic and the percutaneous approach are widely accepted for the drainage of hilar tumors. Our primary objective was to report on the effectiveness and complications of these procedures.

Methods: Prospective observational analysis of the endoscopic and/or percutaneous management of all hilar tumors treated at a referral hospital from October 2011 until October 2014.

[Sphincterotomy plus large balloon dilation versus sphincterotomy alone for the extraction of complex lithiasis: A prospective analysis].

Background And Purpose: Mid-size sphincterotomy associated with large balloon dilation is an alternative to wide sphincterotomy to remove complex lithiases. However, which of the two techniques is most effective remains unclear. Hence, we conducted this study to compare both methods prospectively.

[Quality and competence in endoscopic cholangiography. Towards certainty].

Introduction: The American Society of Gastroenterology (ASGE) and the American College of Gastroenterolog (ACG) have established indicators to recognize high-quality studies in endoscopic retrograde cholagiopancreatography (ERCP). The indicators were: a) Pre-procedure: adequate indication, informed consent, assessment of the degree of difficulty of the procedure and antibiotic prophylaxis. b) Intraprocedure: cannulation, choledocholithiasis extraction and stents placement rates.
