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.

Diagnostic efficiency of ultrasonic tomography (UST) with low-invasive manipulations (LIM) in differential diagnostics of various morphological forms of acute pancreatitis (AP) can be represented in the following table (one of the first examinations). LIM under ultrasonic guidance are specifying diagnostics, therefore, specificity is constant.

A combination of paracentetic treatments (diapeutic LIM) and drainage installation is the basis of the medical LIM in case of complicated acute pancreatitis. Manipulations are carried out in the certain sequence. There is a combination of aspirating needles and drainages of various diameter and type. As a matter of fact, frequency of a puncturation also changes. Medical programs are usually based on the results of organoleptic and analytical examination of the material.

Patients have various clinical forms of acute destructive pancreatitis (AP). Intensity and type of the clinical presentation depend on the phase of the pathological process. Thus, at early phases of acute destructive pancreatitis the signs of enzymatic toxemia prevail. Purulo-septic complications are typical of late phases of the desease.

The changes in blood properties during laboratory research (red blood colour, developed leukocytic formula, leucocytosis, increase in ESR) are auxiliary signs of the disease. The disfunction of the pancreas and liver at different phases of the desease is determined during biochemical investigation.

Ultasonic tomography (UST) is a fast, high-quality non-invasive method of direct diagnostics of acute pancreatitis. We’ve observed a number of sonographic variants of AP.

The enlargement of the pancreas proportionally to the edema is typical of the edematic form of AP. The visible contours of the pancreas are even and clear-cut. Echogenicity of the pancreas is educed diffusely and irregularly in different parts. The local decrease in echogenicity corresponding to the place of the maximum edema is typical of the segmental and local variants of affection. In most cases the echostructure of the parenchyma is homogeneous and the structure of stromal tissue elements was preserved. In case of diffusive affection we usually observe heterogeneity in all parts depending on the degree of the edema. When liquid gathers in the omental bursa we observe an echo-free area of different size as the distance between the back wall of the stomach and the forward surface of the pancreas increased.
