Acute Pancreatitis Diagnosis Summary
Depending on the phase acute pancreatitis (AP) has a polymorphic sonographic picture. Diagnostic accuracy of non-invasive ultrasonic tomography (UST) in verification of the stage of development of AP and character of its complications usually does not exceed 80 % that makes puncture biopsy necesssary.
The basic method to choose the zone to intake the material and make fine-needle biopsy is to reveal necrosis zones with the help of estimation of the blood flow in the pancreatic area in a regimen of color doppler mapping and make comparative estimation of the amount of doppler signals in the thickness of the pancreas and its surface. A 50 % decrease in number of doppler signals serves as a precise marker of necrosis and the destructive process in the pancreas.
Diagnostic fine-needle puncture biopsy (PB) with microbiological and cytologic examination of the aspirate is necessary with patients suspected of the destructive form of AP. Results of PB allow to use LIM under utrasonic guidance differentially and to choose the proper medical treatment in case of various forms of pancreatitis.
When diagnostic fine-needle puncture is used efficiency of the traditional ultrasonic investigation of various forms acute pancreatitis is increased.
