Early Endoscopic Ultrasound (EUS) - Based Sphincterotomy or Conservative Treatment in Severe Biliary Pancreatitis

2014-07-24 14:11:21 | BioPortfolio


The primary purpose of this trial is to determine whether an early EUS immediately followed by an endoscopic sphincterotomy (ES) in case of bile duct stones may improve outcomes in patients with predicted severe acute biliary pancreatitis (ABP).


The management of Acute biliary pancreatitis (ABP) remains controversial. Although early decompression of the bile duct is deemed potentially beneficial, previous randomised studies failed to show the benefit of early endoscopic sphincterotomy (ES) except in selected cases. However, those studies did not use recent non invasive diagnostic methods such as EUS.

Methodology: Patients in the study group undergo EUS followed by ES in case of common bile duct stones within 48 hours of the onset pf symptoms; The control group includes patients with predicted severe ABP undergoing conservative treatment or endoscopic sphincterotomy (without EUS) within 72 hours of the onset of symptoms in case of cholangitis or biliary obstruction.

Medical and Biotech [MESH] Definitions

Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.

A clinical syndrome with acute abdominal pain that is severe, localized, and rapid onset. Acute abdomen may be caused by a variety of disorders, injuries, or diseases.

Acute form of MALNUTRITION which usually affects children, characterized by a very low weight for height (below -3z scores of the median World Health Organization standards), visible severe wasting, or occurrence of nutritional EDEMA. It can be a direct or indirect cause of fatality in children suffering from DIARRHEA and PNEUMONIA. Do not confuse with starvation, a condition in which the body is not getting enough food, usually for extended periods of time.
