Dynamic Terminology It thus seems that while the RAC is a valiant attempt at categorizing AP, especially as it revised a 20 year old classification; it has thrown many new questions.

He commented that DBC appears to develop the scope of the RAC further by creating severity categories that are based on the primary determinants of mortality in AP that closely match the implied basis of RAC. Be sure it is not a pseudoaneurysm Think ahead – What is the plan: Pancreatjtis importance of infection of pancreatic necrosis as an adverse prognostic factor was first reported by Beger et al. The morphological category of acute peripancreatic fluid collections APFC is often a harmless accompaniment of interstitial pancreatitis of generally no consequence [ 4 ].

They may remain sterile or develop infection. Necrosis of peripancreatic tissue can be vary difficult to diagnose, but is suspected when the collection is inhomogeneous, i. The crterios of OF in terms of number of OF has also not been given due importance. The Revised Atlanta Classification discerns 4 types of peripancreatic fluid collections in acute pancreatitis depending on the content, degree of encapsulation and time.

Remarkably, a CT performed 6 months after surgery showed a normal pancreas.

The first CT underestimated the severity of the pancreatitis. Clin Gastroenterol Hepatol ; 9: Implications of culture positivity in acute pancreatitis: As the patient’s condition worsened, a second CT was performed on day 3. Role of ultrasonographically guided fine-needle aspiration cytology in the diagnosis of infected pancreatic necrosis.

No contamination with intestinal flora. A wall surrounds the collection. Thus the concept of a biphasic natural course of AP may be questionable [ 7 ]. Infection is rare during the first week.

Not transgastric route for diagnosis only. In a recent study by Rana et al.

The retroperitoneal approach has some advantages: Therefore, performing CT on day rciterios admission atlxnta for prediction purposes is not recommended. The images are of a patient with acute pancreatitis.

Pseudocyst This patient presented with a gastric outlet obstruction 2 months after an episode of acute pancreatitis. J Nucl Med ; Two weeks later there are gas bubbles in the peripancreatic collection consistent with an infected acute necrotic collection. Most collections that persist after 4 weeks are walled-of-necrosis. The final consensus was reviewed, and only statements based on published evidence were retained.

In a recent review, Nadkarni et al. Confusion in the imaging ranks: This patient underwent surgery. The optimal interventional strategy for patients with suspected or confirmed infected necrotizing pancreatitis is initial image-guided percutaneous retroperitoneal catheter drainage or endoscopic transluminal drainage, followed, if necessary, by endoscopic or surgical necrosectomy.

Am J Gastroenterol Revised Atlanta Classification for Acute Pancreatitis: Relationship of necrosis to organ failure in severe acute pancreatitis. Acute pancreatitis is a pathology that is produced by inflammation of pancreatic tissue and the subsequent release of pancreatic criteris.

While colonic necrosis has been considered in the RAC, necrosis and fistulization of other sites has not been given due recognition. Am J Gastroenterol ; In the early phase of the pancrsatitis, the classification of severity is to be based on the presence or absence of persistent OF and in the late phase, it is to be based on the different morphologic characteristics of local complications evaluated by radiologic imaging and the need for active intervention there of operative, endoscopic, laparoscopic, or percutaneous or other supportive measures such as need for respiratory ventilation or renal dialysisas well as on the presence or absence of persistent OF.


Moreover the emerging data on extrapancreatic necrosis needs to be considered in severity stratification. More Than Just 4 Categories of Severity. In this patient there is normal enhancement of the pancreas with surrounding septated heterogeneous acute necrotic collections with fluid- and fat densities.

As more data emerge and the complexities of the spectrum of acute pancreatitis unfold, key concepts are likely to get revised. Here we see a homogeneous pancreatic and peripancreatic collection, well demarcated with an enhancing wall, on day 25 of an episode of acute necrotizing pancreatitis.

Walled-off Necrosis – WON Based on CT alone it is sometimes impossible to determine whether a collection contains fluid only or a mixture of fluid criterois necrotic tissue. Clinical outcome Early severity stratification of acute pancreatitis is important to identify patients with the highest morbidity. The terms pancreatic atlantw and intrapancreatic pseudocyst are totally abandoned in this new classification.
