Biliary and pancreatic duct pressures measured by ERCP manometry in patients with suspected papillary stenosis

Abstract

Papillary stenosis is an imprecisely defined clinical syndrome which eludes definitive diagnosis. In this study we evaluated 26 patients with suspected papillary stenosis by manometric examination of the sphincter of Oddi done during ERCP examination. Basal pressure in the sphincter of Oddi was elevated in 14 of the patients. Of these 14 patients, 10 underwent sphincterotomy and all experienced improvement in clinical symptoms after their surgery. We suggest that ERCP manometry is a useful procedure for identifying patients with papillary stenosis who may benefit from sphincterotomy.
