Myocardial infarction without coronary artery obstruction (MINOCA) is a clinical syndrome characterized by clinical evidence of myocardial infarction with normal coronary arteries or with nonsignificant stenosis in coronary angiography equal to or less than 50%. MINOCA is a clinical syndrome with multiple etiologies that can affect both epicardial vessels and microcirculation, with a prevalence of 6%.

This study considered 412 patients who underwent ERCP, from January 2010 to December 2014. Unsuccessful ERCP were excluded and the remaining patients were divided into two age groups: <60 years (Group 1) and >60 years (Group 2). They were analyzed according to gender, indications of ERCP, radiologic findings, therapeutic success and occurrence of immediate adverse events.The main indication in both groups was choledocholithiasis. In group 2, the number of cases of acute cholangitis (p = 0.001), biliary stenosis (p = 0.002) and papillary cancer (p = 0.046) was increased. In this group the indication of urgency ERCP was higher (p = 0.042) as well as the diagnosis of dilatation of the bile duct (p < 0.001). In group 1, successful catheterization and the chance of getting the bile duct clear were significantly higher than in group 2 (p = 0.016, OR = 2.1).The main indications of ERCP were choledocholithiasis, acute cholangitis and biliary strictures. The most frequently performed procedure in both groups was the insertion of prostheses, but more frequently in group 2. On the other hand, in the group of young patients, the success of catheterization and the chance to achieve complete clearance of the biliary tract was significantly higher.

b)clear all the hydatid cysts remaining inside the main hepatic duct. c)disconnecting the biliary tract of the hydatid cavity. d)performing a procedure that avoids the biliary stricture and respecting the morphological integrity of the bile duct, when it's possible.
