Emergency Ultrasound of the Gallbladder

The purpose of this study is to determine whether fasting for 8 hours prior to ultrasonography for cholelithiasis (gallbladder pain) is needed.


Ultrasonography of the gallbladder is currently the diagnostic modality of choice in determining cholelithiasis and cholecystitis. Historically this test has been performed in the Radiology suites where the patient was expected to fast for times of six to ten hours. Patients presenting to emergency departments (ED) have also been required to wait to have their study performed in order to have better visualization of the gallbladder. However, few studies have examined whether a fasting time matters in determining gallbladder pathology. Furthermore, with the emphasis on through-times in the ED, most EDs cannot afford holding their patients in the ED to wait for a test. Finally, with the advent of emergency bedside ultrasonography and the greater level of comfort emergency physicians (EP) have in diagnosing gallbladder pathology, it is possible to now determine an answer within minutes. We will test to see if EPs trained in the use of emergency bedside ultrasound can effectively and efficiently determine gallbladder pathology and if fasting has an impact on their ability to perform a quality ultrasound.

Medical and Biotech [MESH] Definitions

Diseases of the GALLBLADDER. They generally involve the impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, neoplasms, or other diseases.

A process whereby bile is delivered from the gallbladder into the duodenum. The emptying is caused by both contraction of the gallbladder and relaxation of the sphincter mechanism at the choledochal terminus.

Tumors or cancer of the gallbladder.

The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.

Diseases in any part of the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.
