Revised Atlanta Classification of Acute Pancreatitis The table summarizes the CT criteria for pancreatic and peripancreatic fluid The CT severity index (CTSI) combines the Balthazar grade ( points) with the extent. The Ranson’s Criteria for Pancreatitis Mortality Estimates mortality of patients with pancreatitis, based on initial and hour lab values. A search of MEDLINE via the OVID interface using the MeSH term “acute pancreatitis” limited to clinical trials, reviews, guidelines, and meta-analysis for the.

However the amylase level was within normal levels. Cytokine cascades result in a systemic inflammatory response syndrome SIRSwhich increases the risk of organ failure. The acute pancreatitis AP keeps on being one of the gastrointestinal pathologies with more incidence and that can unchain a significative mortality. 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.

Balthazar E Case 2: Consequently it is sometimes better to describe these as ‘indeterminate peripancreatic collections’. These images are of a patient who presented with acute severe epigastric pain very suggestive of acute pancreatitis.

Drain runs parallel to pancreatic bed. Allow for demarcation of collections, which takes about 4 weeks. There were no complications and the diagnosis of mild pancreatitis was made.

Same compartment as the pancreas. This patient presented with a gastric outlet obstruction 2 months after an episode of acute pancreatitis. Morphologic severity of acute pancreatitis including pancreatic parenchymal necrosis can only be reliably assessed by imaging 72 hours after onset of symptoms.

Calc Function Calcs that help predict probability of a disease Diagnosis. As it is pointed in some studies, the APACHE-II scale at the moment of admission is not to be trusted to neither diagnose pancreatic necrosis nor severe pancreatitis Services on Demand Journal. Preferred locations of fluid collections are: Prognostic indicators in acute pancreatitis: Early – first week Only clinical parameters are important for treatment planning and are determined by the systemic inflammatory response syndrome – SIRS, which can lead to organ failure.


These collections develop early in the course of acute pancreatitis.

Pancreas – Acute Pancreatitis 2.0

Necrosis of only extrapancreatic tissue without necrosis of pancreatic parenchyma less common. Take home messages Be familiar with the terminology in acute pancreatitis using the Revised Atlanta Classification.

Am Fam Physician ; Not transgastric route for diagnosis only. There were included patients of any gender above the age of 18, with diagnosis of acute pancreatitis of any etiology, who had performed an abdominal tomography 72 hours after the beginning of the clinical condition in order to stage the pancreatic damage. Unable to process the form. 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.

EmBalthazar et al. Since the diagnosis of acute pancreatitis is usually made abltazar clinical and laboratory findings, an early CT is only recommended when the diagnosis is uncertain, or in case of suspected early complications such as bowel perforation or ischemia.

This patient had no fever or signs lara sepsis. Until the present day there are few studies in literature that try to correlate these differences, this is why we have focused on the performance of a study in our hospital, trying to observe how frequent is the discrepancy between the severity degree and the tomographic finds according to the Balthazar classification. Temporallytwo phases of acute pancreatitis are identified in the Revised Atlanta Classification: Morphologically there are 2 types of acute pancreatitis – interstitial or oedematous pancreatitis and necrotizing pancreatitis.

In terms of organ failure and development of pancreatic necrosis, the most severe pzra pancreatitis happen at the E Balthazar degree 1,2. Here a patient with several homogeneous peripancreatic collections on CT. If the CT is performed before this period, the results abltazar be lower Balthazar degrees. The radiologic image is used to confirm or exclude the clinical diagnosis, establish the cause, evaluate the severity, detect complications and provide a guide for therapy 9.


Log in Sign up. The most frequent etiology was due to alcohol FNA and Drainage Once the clinical condition of the patient deteriorates and the patient is febrile, fine needle aspiration FNA can be used to differentiate between sterile and infected collections. Communication with the pancreatic duct may be present.

Approximately half of the deaths happen during the first week due to multi-organ systemic failure A critical evaluation of laboratory tests in acute pancreatitis. The CT shows a similar collection of fluid density to that of the patient with the pseudocyst, except for its pancreatic location.

Serum lipase or amylase activity at least three times greater than the upper limit of normal.

Usually the necrosis pancreatitls both the pancreas and the peripancreatic tissues. Complete encapsulation in pseudocyst and WON. Important remarks concerning Drainage: This patient died on day 5 due to severe SIRS and multiple organ failure.

Reproducibility in the assessment of acute pancreatitis with computed tomography

When peripancreatic collections persist or increase, it is usually due to the presence of fat necrosis. Preferred locations of fluid collections are:. There are 3 subtypes of necrotizing pancreatitis: Endoscopic or percutaneous drainage would have little or no effect on its size, but increases the risk of infection.

Interstitial pancreatitis Morphologically there are 2 types of acute pancreatitis – interstitial or oedematous pancreatitis and necrotizing pancreatitis.
