  • Biliary Dyspepsia: Functional Gallbladder and Sphincter of Oddi Disorders
    Chapter 7 Biliary Dyspepsia: Functional Gallbladder and Sphincter of Oddi Disorders Meena Mathivanan, Liisa Meddings and Eldon A. Shaffer Additional information is available at the end of the chapter http://dx.doi.org/10.5772/56779 1. Introduction Biliary-type abdominal pain is common and often presents a clinical challenge for physicians. True biliary colic consists of episodes of steady pain across the right upper quadrant and epigastric regions, lasting from 30 minutes to 6 hours [1]. Such abdominal pain, when it lasts longer than 6 hours, is likely due to complications of gallstone disease such as acute cholecys‐ titis or acute pancreatitis, or represents a non-biliary source of pain [1]. 1.1. Cholelithiasis, biliary pain and atypical dyspepsia Classical biliary pain that occurs in the setting of gallstones represents symptomatic choleli‐ thiasis. The symptoms associated with gallstones however are frequently confusing. In fact, only 13% of people with gallstones ever develop biliary pain when followed for 15–20 years [2], meaning that most (70-90%) patients with gallstones never experience biliary symptoms. Vague dyspeptic complaints like belching, bloating, flatulence, heartburn and nausea are not characteristic for biliary disease [3, 4]. Therefore, it is not surprising that cholecystectomy often fails to relieve such ambiguous symptoms in those with documented gallstones. In fact, cholecystectomy fails to relieve symptoms in 10-33% of patients with documented gallstones [5]. If the abdominal pain is misdiagnosed and instead due to functional gut disorders like irritable bowel syndrome, cholecystectomy would not provide a favorable outcome [4, 5, 6]. 1.2. Functional gallbladder disease Biliary-type abdominal pain (also termed biliary colic) in the context of a structurally normal gallbladder has been referred to as “biliary dyspepsia”.

  • Sphincter of Oddi Dysfunction, Manometry, Oddi Disorder
    Journal of Medicine and Life Vol. 1, No.2, April-June 2008 The functional sphincter of Oddi disorder Corina Pop, Adina Purcăreanu, Monica Purcărea, Dan Andronescu Department Of Gastroenterology And Internal Medicine University Hospital Bucharest Correspondence to: Dan Andronescu, M.D., Ph.D., Emergency Universitary Hospital Bucharest, Splaiul Independentei 169, Bucharest 050098, Romania Abstract The sphincter of Oddi disorder (SOD) has been a controversial subject for many years, about which a lot has been written. However, new findings mainly using Endoscopic Retrograde Cholangiopancreatography (ERCP) and sphincter of Oddi manometry (SOM) demonstrate the fact of this diagnostic. SOD is just a part of a larger pathology, the functional gastrointestinal disorders, which have been reconsidered as an important part of gastrointestinal diseases. For a better understanding, the American Gastroenterology Association Institute created a new classification of The Functional Gastrointestinal Disorders in 2006, Rome III Classification, in which the SOD is grouped in the functional biliary disorders (category E). The term SOD is used to define manometric abnormalities in patients who have signs and symptoms consistent with a biliary or pancreatic ductal origin. Based on the pathogenic mechanism and manometry findings, the SOD is separated into two groups: a group characterized by a stenotic pattern (anatomical abnormality) and a second group with a dyskinetic pattern (functional abnormality). The purpose of this article is to construct a short presentation of the main aspects regarding functional SOD (E2 and E3 after Rome III Classification). Keywords: sphincter of Oddi, functional disorder, sphincter of Oddi dysfunction, manometry, Oddi disorder Introduction Functional biliary disorders are common gastrointestinal diseases seen in general practice and by the gastroenterologist.
