Schwannomas are benign tumors originating from Schwann cells, which the main component of neural sheath. Biliary schwannomas extremely rare. We report case a 78-year-old man who presented with no abdominal symptoms or jaundice. CT imaging showed hyperdense mass extending along extrahepatic bile duct, and upstream ducts were dilated. performed duct resection under preoperative diagnosis cancer. ...

Sheep antibodies raised against three isoenzymes of glutathione S-transferase (EC 2.5.1.18), transferases B, C, and E, which were isolated and purified to apparent homogeneity from rat liver, have been employed to localize these enzymes at the light microscopic level within livers of untreated rats. Using these antibodies in an unlabeled antibody peroxidase-antiperoxidase staining technique, ea...

BACKGROUND From the 1990's onward, it has been possible to assess changes in the lacrimal duct by direct, minimally invasive diagnostic inspection with the aid of miniaturized endoscopes originally used in gastroduodenal surgery. It has been shown in this way that mechanical lacrimal duct stenosis often develops gradually as the result of recurrent chronic inflammation. Absolute stenoses are of...

Modern narcotic analgesic drugs, such as tramadol, pentazocine, and buprenorphine share similarities of molecular structure with morphine which is widely believed to cause spasm of the bile duct sphincter and so impede bile flow. This study assessed the effects of intravenously administered analgesics on bile duct sphincter motor activity measured by ERCP manometry. Ten minutes after pentazocin...

thoracic duct is a duct that drains the lymph from the cisterna chily into the venous angle of the cranial vena vava. thoracic duct in the horse is situated on the right side, but in rare cases the left thoracic duct has been reported. in this report the course and left position of the thoracic duct in an embalmed donkey is described. regarding many anatomical similarities between horse and don...

Anatomic variations in forensic extrahepatic bile ducts is common. Knowledge of extrahepatic bile duct variations is important for surgeons in order to prevent iatrogenic damage during surgery. This study aims to determine the variations in extrahepatic bile ducts among 150 cadavers located at the Kerman Medicine Organization. We performed autopsies on 150 cadavers. Bile ducts were exposed an...
