Secondary uncovered versus fully-covered metal stents for the management of occluded stent in unresectable distal malignant biliary obstruction.

Introduction: Self-expandable metallic stents (SEMS) have been widely placed for unresectable distal malignant biliary obstruction (UDMBO). However, the dysfunction rate is 19-40% and its treatment is controversial. We aimed asses the efficacy and safety of a secondary biliary stents (uncovered (UC) versus fully-covered (FC) stent) for the management of occluded SEMS.

Double-Blind Multicenter Randomized Clinical Trial Comparing Glucagon vs Placebo in the Resolution of Alimentary Esophageal Impaction.

Introduction: The aim of this study was to compare the effectiveness of glucagon vs placebo in resolving esophageal foreign body impaction (EFBI), as well as the length of the procedure and adverse events.

Methods: This was a multicenter, randomized, double-blind trial involving consecutive patients diagnosed with alimentary EFBI. Participants were randomized to receive either 1 mg of intravenous glucagon or placebo.

Obstructive jaundice secondary to a hepatic hydatid cyst.

The rupture of a hepatic hydatid cyst into the intrahepatic bile ducts is one the most common and serious complication of hepatic hydatidosis and occurs in 5-25% of cases. (1, 2, 3). Endoscopic retrograde cholangiopancreatography (ERCP) plays an indisputable role in the diagnosis and treatment of this condition.

Readmissions due to acute biliary edematous pancreatitis in patients without cholecystectomy.

Aims: Analyzing the readmission of patients with acute biliary edematous pancreatitis (ABEP) without cholecystectomy despite a previous episode of mild acute gallstone pancreatitis or lithiasic cholecystitis. Calculating the health costs associated with the non-performance of cholecystectomy.

Material And Methods: Prospective observational study conducted at a tertiary hospital from July to November 2014.
