Simultaneous dilation of both the common bile duct and the pancreatic duct (double-duct sign) is usually because of ampullary or pancreatic tumours. Here we report an unusual cause of double-duct dilation; we describe the case of a 49-year-old female who developed afferent loop syndrome after pylorus-preserving pancreaticoduodenectomy: cross-sectional imaging of the abdomen revealed a double-du...

BACKGROUND We performed duct-to-mucosa pancreaticojejunostomy with resection of jejunal serosa in 55 patients, and here compare the clinical results between duct-to-mucosa pancreaticojejunostomies with a non-dilated pancreatic duct and those with a dilated duct. PATIENTS AND METHODS In the period 1999 to 2005, 55 patients (27 F, 28 M; mean age 63.4 years) underwent duct-to-mucosa pancreaticoj...

 Abstract Background: Thyroglossal duct cysts (TDC) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. About 7% of the population have thyroglossal duct remnants. Clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. Thyroglossal duct cysts may r...

Atmospheric duct parameters inversion is an important aspect of microwave-band radar and communication system performance evaluation. AIS (Automatic Identification System) one the signal sources used for atmospheric inversion. Before parameters, determining type plays role in results, but current methods ignore this point. We outlined a classifying-inversion method using signals combined with a...

In this article, a theoretical mathematical model of gas flow through duct in the case local mass and momentum sources sinks is presented. The continuity equation motion with one-dimensional, density-stable flows were used to create model. size their locations have an effect on stream duct, energy losses, parameters mechanical source that causing flow. traditional approach describing concept re...

abstract autoimmune pancreatitis (aip) is a rare disorder that may be present as common bile duct stricture. the patient was a seventy-year-old man with presentations as recurrent abdominal pain and jaundice, elevated billirobin (bil) and elevated alkaline phosphatase (alkp) in association with the presence of hetrogenesity of the pancreatic head and dilated intra and extra hepatic bile ducts i...

A 70-year-old man was referred to our hospital because of elevated hepatobiliary enzymes. He admitted for endoscopic retrograde cholangiopancreatography (ERCP) abdominal echography showed dilatation the intrahepatic bile duct and common duct, contrast-enhanced CT thickening wall lower duct. The large papilla located near inferior border diverticulum could be imaged from front. However, supporti...

BACKGROUND The "classical" biliary injury usually involves misidentification of the common bile duct as the cystic duct. The purpose of this study was to determine if the method of cholecystectomy, specifically the "infundibular technique," might be a contributing factor in this injury. STUDY DESIGN Twenty-one operative notes of patients who were referred with injury to the common bile duct w...
