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...

Two-ship acoustic propagation experiments were conducted in deep waters of the Arabian Sea between 22-25 July and 7-8 August 2002 from onboard INS Sagardhwani ORV Sagarkanya during ARMEX-I phase. The aim this experiment was to understand spatial (up 30 km) temporal 24 hr) fluctuations intensities within surface duct. transmissions made 15m depth at 2.4 KHz 620 Hz frequencies one ship signals re...

Carcinoid tumors of the extrahepatic bile duct are rare and account for only 0.2-2% of all gastrointestinal carcinoids 1, CASE REPORT A 30 yr old man presented with obstructive jaundice while on holiday in Australia. Physical examination was otherwise normal. Abdominal ultrasound, CT scan and MRI scan confirmed marked dilatation of the intrahepatic biliary system. ERCP revealed a stricture in t...

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior seg...
