Pancreas – Acute Pancreatitis 2.0

Which patient is most at risk? Acute oedematous or interstitial pancreatitis. For patients with proven or suspected infected necrotizing pancreatitis, invasive intervention should be preferably delayed until at least 4 weeks after initial presentation to allow collections to become ‘walled-off’.

While most of the older studies had reported that fistulization in patients pancreatiyis AP generally occurred after surgical or radiological intervention [ 505154 ]; recent data suggest that it can occur spontaneously as well [ 5253 ]. Severity stratification, therefore must factor infection of the pancreatic necrosis.

Revised Atlanta Classification for Acute Pancreatitis: A Pictorial Essay.

While a majority of the extra pancreatic complications have been included in RAC [ dd ], a few that may have important bearing on the outcome of AP have not been considered. Incidence and reversibility of organ failure in the course of sterile or infected necrotizing pancreatitis. This case is a typical example of infected pancreatic atlqnta. Mild – No organ failure and no local or systemic complications.

In this review, critegios authors present a practical image-rich guide to the revised Atlanta classification system, with the goal of fostering implementation of the revised system into radiology practice, thereby facilitating accurate communication among clinicians and qtlanta the radiologist’s role as a key member of a multidisciplinary team in treating patients with acute pancreatitis. Route can be used to guide minimally invasive surgery.


The CT shows an acute necrotizing pancreatitis. 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.

A Pseudocyst is a collection of pancreatic juice or fluid enclosed by a complete wall of fibrous tissue It occurs in interstitial pancreatitis and the absence of necrotic tissue is imperative for its diagnosis.

What are the findings? It takes about 4 weeks for a capsule to form. While the need to include the category of MSAP was rightly based critedios data provided by studies from Mayo Clinic [ 6768 ]; the inclusion of fluid collection s as a local complication in categorizing MSAP has been criticized [ 65 ].

In view of the difference in outcomes of those with single OF and those with MOF; categorizing them into a separate severity category may be useful. Other studies have also supported the contention that IN affects survival and occurrence of OF [ 20 – 23 ]. Unable to process the form. Similar observations were made by Buchler et al.

Pseudocysts are uncommon in acute pancreatitis. Jensen, Gene Bakis, Akram M.

Revised Atlanta Classification for Acute Pancreatitis: A Pictorial Essay.

Normal enhancement of the entire pancreas. The Revised Atlanta Classification discerns 4 types of peripancreatic fluid collections in acute pancreatitis depending on the content, degree of encapsulation and time. The RAC has not given due consideration to infected necrosis IN while classifying severity into mild, moderate and severe.


CT CT is the imaging modality of choice for the diagnosis and staging of acute pancreatitis and its complications. It needs to be determined how this can be included in RAC. In our study of patients we identified 12 patients with fistulae none had undergone surgery prior to detection of fistula ; duodenum was the most common site, followed by stomach and colon crigerios 52 ].

The Radiology Assistant : Pancreas – Acute Pancreatitis

A prospective longitudinal study of observation versus surgical intervention in the management of necrotizing pancreatitis. This leads to persistent collections as the viable pancreatic tail continues to secrete pancreatic juices. The terms pancreatic abscess and intrapancreatic pseudocyst are totally abandoned in this new classification. Peripancreatic collections can be approached through the transhepatic red arrowtransgastric green arrow or transabdominal blue arrows route, but the preferred approach is to stay in the retroperitoneal compartment yellow arrows.

These include fistulization [ 50 – 57 ] and vascular complications other than splanchnic thrombosis [ 58 – 64 ]. The revised Atlanta classification for acute pancreatitis: True pseudocysts are uncommon, since most acute peripancreatic fluid collections resolve within 4 weeks. The differential diagnosis includes walled-off necrosis and sometimes a pseudoaneurysm or even a cystic tumor.
