The effect of transcutaneous nerve stimulation on intraductal biliary pressure in post-cholecystectomy patients with T-drainage.

Objective: To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) on intraductal biliary pressure (IDP) in basal conditions and after intravenous morphine and oral meal stimulation.

Design And Methods: Fifteen patients (5 male, 10 female) aged 31-83 years (mean 61.5 +/- 13.

Immediate effects of endoscopic sphincterotomy on sphincter of Oddi motility.

The evidence exists that incomplete sphincterotomy in patients with biliary tract diseases may result in early symptoms reoccurrence or lack of improvement. Sphincter of Oddi manometry (SOM) can be used to verify the completeness of the procedure. The purpose of the study was to investigate the immediate effects of biliary endoscopic sphincterotomy (BES) and common bile duct stones (CBDS) clearance on biliary sphincter of Oddi (SO) motility.

[Sphincter of Oddi motility disturbances--etiologic factor or the consequence of choledocholithiasis].

Unlabelled: Choledocholithiasis is often found in patients after cholecystectomy done previously for cholelithiasis.

Aim: To evaluate the effects of cholecystectomy and common bile stones' presence on sphincter of Oddi (SO) motility.

Material: 13 patients with common bile duct stones (2 men and 11 women, age 54 to 85 yrs) were studied.

Endoscopic sphincterotomy as a therapeutic measure in cholangitis and as prophylaxis against recurrent biliary tract stones.

Our purpose was to analyse the results of endoscopic sphincterotomy in patients with advanced cholangitis, and to assess the potential of this method in the prevention of recurrent biliary tract stones. Advanced cholangitis certainly predisposes to microlith formation, and we believe that the increased biliary drainage produced by sphincterotomy counteracts this process. Our grading of cholangitis was an intraoperative cholangioscopic assessment corresponding to Nishimura grades III and IV (erosions in the duct walls, patchy stone ulceration, biliary gravel, fibro-purulent plaques densely adherent to the biliary walls etc.
