The incidence of bile duct injuries has increased as a consequence of the increasing number of cholecystectomies. However, the results of biliodigestive derivation currently used for bile duct reconstruction are unsatisfactory. We report here the case of a patient with iatrogenic Bismuth II bile duct injury and propose a new technique that permits more anatomical and physiological reconstructio...
thyroglossal duct cyst is a well-known congenital entity, and its embryonic development and clinical presentation are well understood. very little can be added to the classic material found in the world literature. rare cases of unusual clinical presentation have also been reported. our case of endolaryngeal thyroglossal duct cyst is reported because of its unique endolaryngeal presentation, ha...
PURPOSE The segmental resection of constricted bile duct and end-to-end biliary anastomosis could be an attractive alternative in the treatment of benign biliary tract stricture. The aim of this study was to restore the anatomical integrity of the hepatic-common bile duct after an artificially produced defect while maintaining the large duodenal papilla, using microsurgical technique. MATERIA...
PURPOSE To identify the value of unilateral pedal lymphangiography (LAG) with non-contrast CT in the location and treatment decision of idiopathic chylothorax after failure of thoracic duct ligation. MATERIALS AND METHODS Twenty four patients aged 9-84 year old (median 44 yr) who had idiopathic chylothorax were involved, and unilateral pedal LAG with non-contrast CT was performed in every pat...
A 57-year-old man underwent endoscopic retrograde cholangiopancreatography (ERCP) for multiple bile duct and gallbladder stones. During the ERCP, we attempted to insert a prophylactic 5-Fr, single pigtail pancreatic stent (Cook Endoscopy, Winston-Salem, North Carolina, United States) because biliary cannulation is difficult and the pancreatic duct is frequently cannulated unintentionally; howev...
k This study investigated the Navier-Stokes L computations of the surface heat transfer coefficients of a transition duct flow. A transition duct from an axisymmetric n cross section to a nonaxisymmetric cross section, is usually used to connect the turbine exit to the nozzle. As the gas Pr turbine inlet temperature increases, the transition duct is subjected to the high temperature at the gas ...
The so-called "Postcholecystectomy Syndrome" may be due to various pathological biliary causes. The aim of this study was to evaluate the significance of the cystic duct stump syndrome and if so, how often a long (greater than 1.5 cm) cystic duct stump was an indication for reoperation on the bile ducts after cholecystectomy in our patients. Three hundred and twenty two patients underwent a sec...
BACKGROUND A report of multiple cases of bile duct cancer at a Japanese printing company raised concern about such cancers. We examined long-term trends in bile duct cancer in Japan. METHODS Data from 4 population-based cancer registries were used to calculate incidence between 1985 and 2007, and vital statistics were used to estimate mortality between 1985 and 2011. Age-standardized rates we...
In this study, aerodynamic and acoustic measurements were obtained in a dynamic mechanical model of the larynx and vocal tract. The model consisted of a uniform duct, intersected by a pair of sinusoidally oscillating shutters. A controlled airflow along the duct was periodically disturbed by the action of the shutters and pressure, and flow velocity measurements were obtained in the region down...
The occurrence of biliary stricutures in allografts following liver transplantation correlates with the duration of preservation time. The correlation between preservation time and biliary strictures suggests that anoxic or reperfusion injury of the bile duct epithelium causes stricture formation. However, the relative susceptibility of bile duct cells to anoxic or reoxygenation injury is unkno...
