Is ERCP manometry useful in the choice of treatment of stones of the common bile duct?
1988
To verify the appropriateness of sphincterotomy as the treatment of choice of choledocholithiasis, since 1980 we have been using endoscopic retrograde cholangiopancreatographic (ERCP) manometry of the sphincter of Oddi (SO). This method allows direct investigation of SO motor activity and provides useful information regarding the presence of benign papillary stenosis (BPS). Thirty-four patients were investigated because the radiological examination indicated BPS might be present. Of these, 20 had common bile duct (CBD) stones, while the remaining 14 presented with biliarylike pain and one or more of the following: CBD dilation (larger than 12 mm); emptying of the ERCP contrast medium took l…
Percutaneous antegrade electropapillotomy. Study in dogs.
1984
Antegrade electropapillotomy using the percutaneous transcystic approach was successfully performed in 11 of 16 dogs. When the intervention was effective, the pressure gradient between common bile duct and duodenum decreased from 6 to 1.3 mm Hg on average and returned to gradients slightly below the initial values after 4 weeks, owing to reactivation of the sphincter mechanism. Ineffective cutting, however, resulted in a temporary pressure rise. In one dog a papillary stenosis developed and was relieved by antegrade electrocutting. Irrespective of the success of the papillotomy, rises in levels of serum glutamine oxaloacetic and pyruvic transaminase, alkaline phosphatase, serum amylase and …
