We performed an ERCP, which revealed 2 cm ampullary lesion with upstream obstruction. • Conflicting evidence regarding any survival benefit from metal vs plastic stent in this setting • Plastic: patency 2-5mos Double duct sign; ERCP is needed for more evaluation. One is insertion of DBE and the other is an ERCP‐related . The double duct sign. Double duct sign is an anatomical sign of combined dilatation of common bile duct and pancreatic duct. Double-duct sign, on MRCP and/or CT of the pancreatobiliary system, refers to co-existing dilatation of the CBD and PD. 3. Although the diagnosis of malignant bile duct obstruction can be established by ultrasonography, the evaluation of tumour site and disease extent requires direct cholangiopancreatography.

(B) A 3D MRCP image shows a DBS with abrupt, eccentric and asymmetric narrowing, obtuse angle of the narrowing end, irregular margins, and the presence of the double duct sign (white arrow). The ERCP suggests a "double duct" sign. The double duct sign refers to the presence of simultaneous dilatation of the common bile and pancreatic ducts. Cholangitis is the infection of the common bile duct, which transmits the body's bile to the intestines and gallbladder from where bile is created in the liver. In this case the stricture appears quite distal. We wish to investigate the prognostic value of the "double-duct" sign in patients who undergo Magnetic resonance cholangio-pancreatography (MRCP), attempting to define the . Initially, the double duct sign was thought to predict the presence of pancreatic carcinoma with a specificity approaching 100%. Patients with obstructive jaundice in the context of a double-duct sign have a high incidence of malignancy [7-9]. ERCP showing a distal bile duct stricture raising concern for Double duct sign; ERCP is needed for more evaluation.

Further ERCP is needed for more evaluation. Analysis of Bile Duct Dilation We observed intrahepatic and extrahepatic bile duct, and pancreatic duct dilation in pan-creatic head cancer cases. 2002 biopsy forceps. Introduction "Double-duct" sign on ERCP (Endoscopic retrograde cholangio-pancreatogram) is considered suggestive of pancreatic or biliary malignancy. The pathology confirmed an ampullary carcinoma. APPEARANCE The double duct sign is a finding seen at magnetic resonance (MR) cholangiopancreatography (a two-dimensional technique) and consists of simultaneous dilatation of the common bile and pancreatic ducts ( Figure ) ( 1 , 2 ). Magnetic resonance cholangiopancreatography (MRCP) is a technique that has evolved over the past two decades. Figure 2. Main types of infection after ERCP include cholangitis and cholecystitis.

The "double-duct sign" refers to the simultaneous dilatation of the common bile duct (CBD) as well as the pancreatic duct (PD) and was originally described during endoscopic retrograde cholangiopancreatography (ERCP) [1, 2].It has long been considered an ominous finding, potentially suggestive of malignancy of the pancreatic head or ampulla of Vater []. The results suggest that ERCP is an accurate and reliable method for diagnosing pancreatic carcinoma. Double duct sign; ERCP is needed for more evaluation. It can help to diagnose conditions of the liver, bile ducts, pancreas or gallbladder. Findings suggestive of a tumor/mass include super-impassable strictures, obstruction of the common bile and pancreatic ducts (the "double duct" sign), a pancreatic duct stricture in excess of 1 cm in length, pancreatic duct obstruction, and the absence of changes suggestive of chronic pancreatitis. This video shows the insertion of a metallic biliary stent in a patient with inoperable pancreatic cancer. Gastrointest Endosc.
