Ecografie — Abdomen țintit: vezică biliară (MCB)

ABDOMEN LIMITED (GALLBLADDER ONLY) US PROTOCOL

PURPOSE:

 To evaluate the gallbladder and extrahepatic bile duct for any abnormalities.

INDICATIONS:

 Upper abdominal, right upper quadrant or epigastric abdominal pain.  Known or suspected cholelithiasis or biliary obstruction.  Comments section must indicate Gallbladder (or GB) Only protocol.

EQUIPMENT:

 3-5 MHz linear or curved probe

PATIENT PREPARATION & ASSESSMENT:

 The patient should be NPO after midnight or 6-8 hours prior to examination.  Introduce yourself to the patient.
 Verify patient identity via two patient identifiers (name and date of birth) per hospital policy.  Explain the examination, its purpose and how long it will take.  Answer any questions the patient may have regarding the examination.  Obtain patient history including symptoms, signs, risk factors and other relevant history.

GENERAL GUIDELINES:

 Send the measurements screenshot page if your machine is capable.  For focal lesions (masses, cysts, nodules, lymph nodes, fibroids) obtain split-screen images of the lesion without calibers, with calibers and with Color Doppler.
 Any deviations from the standard protocol and any limitations to the examination should be documented on the technologist worksheet for future reference and for repeatability in follow-up studies.  Report preliminary critical findings to the referring clinician when appropriate (i.e. immediate medical attention may be warranted) and according to hospital policy.

 Body  Fundus
 Measure wall thickness (normal <3mm)  Document longitudinal images in left lateral decubitus position of the following:  Neck  Body  Fundus  Document transverse images in left lateral decubitus position of the following:  Neck  Body  Fundus  Assess for gallbladder distention (normal <10 cm in length), sonographic Murphy’s sign and pericholecystic fluid.  Measure the largest stone in one dimension.  If a stone does not shadow with an increased frequency transducer, use Color Doppler to demonstrate twinkling artifact sign.  For non-stone pathology (mass-like sludge, masses, nodules), document color and spectral Doppler images of the pathology. Sludge will not have blood flow. Masses will have blood flow.

Bile Ducts  Document images of the following:  Common bile at the porta hepatis without and with measurement (normal <6 mm up to 60 years then add 1 mm per decade of age up to 10 mm post cholecystectomy).  Document color Doppler image of common bile duct (at the hepatic artery and main portal vein)  Assess for dilatation of the intrahepatic bile ducts if there is dilatation of the common bile duct.
