Investigation of the Effect of Duodenoscopy on Sphincter of Oddi Manometry

1991

To investigate whether endoscopy affects sphincter of Oddi (SO) manometry, three patients who had undergone previous cholecystectomy and had a T-tube in situ for drainage were studied. Manometry was performed using a perfused triple lumen manometry catheter (diameter 1.7 mm), which was advanced into the SO lumen through the T-tube. SO motility, baseline pressure, common bile duct pressure and duodenal pressure were monitored before and during endoscopy while the tip of the endoscope was in the mouth, esophagus (upper third, precardial), stomach and duodenum. Endoscopy and even a moderate insufflation of air necessary to pass the pylorus and inspect the papilla of Vater did not affect the pa…

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…

Pharmacology of the Sphincter of Oddi

1988

The sphincter of Oddi is the smooth muscle connection between the bile duct and the duodenum. Its physiological function is associated with a regular motility characterized by phasic contractions superimposed on the sphincter of Oddi baseline pressure. Recently introduced ERCP-manometry permits further studies of sphincter of Oddi pharmacology. A number of drugs have so far been studied. Sedatives of the diazepam type had no effect on the sphincter, while butylscopolaminium bromide, a typical neurotropic agent, brings about cessation of the sphincter motility for 3-8 minutes. Hymecromon lowered the sphincter baseline pressure from 9.8 to 7.8 mmHg. A 1.2 mg sublingual dose of nitroglycerin, …

Sudden severe abdominal pain after a single low dose of paracetamol/codein in a cholecystectomized patient: learning from a case report.

2009

We report the case of an elderly patient with diastolic heart failure and renal insufficiency admitted to hospital as he complained of having a history of hypogastric pain and dysuria without fever due to renal lithiasis and urinary infection. Because the pain was persistence, and considering the presence of renal dysfunction, it was administered a single low dose of paracetamol/codein (500/30 mg). After about 1 hour of the administration, he suddenly complained of the onset of a lancinating epigastric pain radiating to the whole abdomen and retrosternum accompanied by nausea. The electrocardiogram (EKG) was negative for myocardial infarction and computed tomography excluded aortic dissecti…

Biliary Pancreatitis: Endoscopic Diagnostic and Therapeutic Techniques

1987

Acute pancreatitis constitutes one of the most hazardous emergencies in clinical gastroenterology. Although the diagnosis “biliary pancreatitis” is often used in clinical practice for patients presenting with concrements in the biliary tree or impacted in the papillary orifice [17, 32], the common phrase “biliary pancreatitis” has not so far been exactly defined. Patients with cholecystolithiasis may be included in this group, as well as patients with dysfunction of the sphincter of Oddi. Some authors have reported that juxtapapillary diverticula increase the risk for development of biliary pancreatitis [28].
