1. Manometria biliar em pacientes submetidos à colangiopancreatografia retrógrada endoscópica / Biliary manometry in patientes referred to ERCP
Introdução: A manometria do esfíncter de Oddi (MEO) é o padrão ouro para diagnóstico de disfunção do esfíncter de Oddi (DEO). A prevalência desta alteração em pacientes encaminhados à colangiopancreatografia retrógrada endoscópica (CPRE) e a sua importância clínica são desconhecidas no meio acadêmico brasileiro. Objetivos: Avaliar a preval

2. Prospective comparison of secretin‐stimulated MRCP with manometry in the diagnosis of sphincter of Oddi dysfunction types II and III
Is the role of secretin in causing a choleresis clinically significant enough to be a “stress test” for biliary SOD?

3. Congenital choledochal dilatation with emphasis on pathophysiology of the biliary tract.
Of 37 patients with congenital choledochal dilatation, aged 8 days to 12 years, who had undergone excision with Roux-en-Y hepaticojejunostomy, 26 patients could be analyzed for morphologic abnormalities and pathophysiology of the biliary tract. Of the 26 patients with congenital choledochal dilatation, 25 (96.2%) had an abnormal choledochopancreaticoductal j

4. Manometric diagnosis of sphincter of Oddi spasm as a cause of postcholecystectomy pain and the treatment by endoscopic sphincterotomy.
Seventeen patients with postcholecystectomy pain and nine controls were studied by nonoperative biliary manometry with stimulation of sphincter of Oddi spasm by morphine. The controls remained asymptomatic despite an elevation of bile duct pressure after morphine. In 13 patients with postcholecystectomy pain, morphine induced pain paralleling a pressure rise

5. Topical glyceryl trinitrate relaxes the sphincter of Oddi.
BACKGROUND/AIM: Nitric oxide (NO) may be involved in non-adrenergic non-cholinergic (NANC) inhibitory innervation of the sphincter of Oddi (SO). The effects of topical application of glyceryl trinitrate (GTN), a NO donor, upon SO motility were examined. METHODS: Nineteen patients undergoing routine SO manometry for investigation of abdominal pain were studie

6. Inhibition of sphincter of Oddi function by the nitric oxide carrier S-nitroso-N-acetylcysteine in rabbits and humans.
Nitric oxide (NO) is an inhibitor of gastrointestinal smooth muscle. Model systems of the gut predict the NO will complex with biological thiol (SH) groups, yielding S-nitrosothiols (RS-NO), which may limit the propensity to form mutagenic nitrosamines. The inhibitory effects of NO and its biologically relevant adducts on sphincter of Oddi (SO) motility have
