Manometric study of the sphincter of Oddi in patients with and without common bile duct stones.
Motor activity of the sphincter of Oddi has been evaluated in 34 patients who underwent ERCP examination. Manometric recordings from the common bile duct and the sphincter of Oddi were performed with a polyethylene triple lumen catheter. At ERCP 16 patients had undamaged biliary ducts; six had undergone cholecystectomy and six had gall bladder stones; 18 patients had common bile duct stones; ni...
متن کاملEUS and Common bile duct stones
Choledocholithiasis is a common disorder, especially in patients older than 60 years, as common bile duct stones may be present in 15% to 60% of cases in this special sample of population. Until recently, endoscopic retrograde cholangiography (ERC), which is a very reliable method for visualizing and extracting gallstones in the same session, was considered the gold-standard for suspected chole...
متن کاملEffects of trypsin, thrombin and proteinase-activated receptors on guinea pig common bile duct motility.
Trypsin and thrombin activate proteinase-activated receptors (PARs), which modulate gastrointestinal motility. The common bile duct is exposed to many proteinases that can activate PARs, especially during infection and stone obstruction. We investigated PAR effects on common bile duct motility in vitro. Contraction and relaxation of isolated guinea pig common bile duct strips caused by PAR(1), ...
متن کاملTransient increase in the common bile duct diameter after laparoscopic and open cholecystectomy
Introduction: Increase in the common bile duct diameter after cholecystectomy has been reported in animal model. However, similar studies in the human resulted in controversy. Methods: Between 2008 and 2012, fifty two patients with clinical as well as radiological signs and symptoms of gallbladder disease were enrolled in this study. The patients underwent laparoscopic and open cholecystectomy ...
متن کاملRisk tolerance and bile duct injury: surgeon characteristics, risk-taking preference, and common bile duct injuries.
BACKGROUND Little is known about surgeon characteristics associated with common bile duct injury (CBDI) during laparoscopic cholecystectomy (LC). Risk-taking preferences can influence physician behavior and practice. We evaluated self-reported differences in characteristics and risk-taking preference among surgeons with and without a reported history of CBDI. STUDY DESIGN A mailed survey was ...
