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. Em , Balthazar et al. Critérios subjetivos foram utilizados para definir a diferenciação entre líquido coletado e líquido livre inflamatório, uma vez que. The BISAP Score for Pancreatitis Mortality predicts mortality risk in pancreatitis with fewer variables than Ranson’s.

Lesser sac Anterior and posterior pararenal space of the retroperitoneum. The diagnosis crjterios acute pancreatitis was established with 2 of the 3 following criteria: Central gland necrosis Central gland necrosis is a specific form of necrotizing pancreatitis, representing full thickness necrosis between the pancreatic head and tail and is nearly always associated with disruption of the pancreatic duct.

Most persistent fluid collections also contain some necrotic material. The tomographic evaluation was performed by Mexico’s General Hospital radiologists and was reported according to the A and E degree of the tomographic Balthazar criteria. Am J Gastroenterol ; Or create a new account it’s free.

There is a homogeneous well-demarcated peripancreatic collection in the pancreatitls sac, which abuts the stomach and the pancreas. When peripancreatic crkterios persist or increase, it is usually due to the presence of fat necrosis. Same compartment as the pancreas.

Enter your email address and we’ll send you a link to reset your password. Due to the seriousness that an AP condition implicates, different prognosis methods have been developed that can indicate us in a specific way the most likely outcome of each patient. Drain runs parallel to pancreatic crierios. The collection underwent successful percutaneous drainage, which showed clear fluid with high amylase and subsequently resolved along with the patient’s symptoms.

Here a patient with several homogeneous peripancreatic collections on CT. Important remarks concerning FNA: Pseudocysts are uncommon in acute pancreatitis. To save favorites, you must log in. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. A modified CT severity index for evaluating acute pancreatitis: These collections are the result of the release of activated pancreatic enzymes which pancreaitis cause necrosis of the surrounding tissues.


Although the imaging characteristics in this case are similar to the patient with the pseudocyst, this proved to be infected walled-off-necrosis. 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 and necrotic tissue.

Allow for demarcation of collections, which takes about 4 weeks. Balthazar E Case 1: These cases illustrate that at times CT cannot reliably differentiate between collections that consist of fluid only and those that contain fluid and solid necrotic debris with or without infection. Late – after the first week Morphologic criteria based on CT findings combined with clinical parameters determine the care of the patient.

The objective of this study was to correlate the severity degree of the acute pancreatitis according to the Ranson, APACHE-II criteria, and the determination of the serous hematocrit at the moment of admission, with the local pancreatic complications according to the tomographic Balthazar criteria, in order to give a better prognosis value to the tomographic finds in relation with the AP severity. Diagnosis of Acute Pancreatitis The diagnosis of acute pancreatitis requires two of the following three features: It was not possible on bakthazar second study to measure it on all of the patients, but in xriterios posterior study it would be of great importance to correlate these parameters in order to look for a better indicator to make the decision of performing or not a tomographic study in patients with slight AP.

The measurement of observer agreement for categorical data.

An early CT may be misleading regarding the morphologic severity of the pancreatitis, because it may underestimate the presence and amount of necrosis. Let us hope that in a future we can ve out our finds in a more concrete way. There is normal enhancement of the entire pancreatic gland with only mild surrounding fatty infiltration. Todos os exames foram avaliados analisando-se inicialmente as imagens da fase sem contraste venoso e, posteriormente, as imagens das fases sem e com contraste venoso, conjuntamente.

Corelation among clinical, biochemical and tomographic criteria in order to evaluate the severity in acute pancreatitis. Balthazar C Case 3: Pseudocyst This patient presented with a gastric outlet obstruction 2 months after an episode of acute pancreatitis. Remarkably, a CT performed 6 months after surgery showed a normal criteruos. Many of these patients however will have necrotizing pancreatitis and the mortality increases when the necrosis becomes infected.


balthasar Ninety-two point nine per cent of the patients had less than 3 Ranson criteria of which The number of patients of this study does not allow us to conclude in a categorical way the absence of correlation between the tomographic Balthazar finds and the clinical and biochemical scales previously mentioned, how-ever it encourages us to carry on with this research. Discussion On this study we found that in our hospital service we have a low frequency of the disease.

Infected necrosis Infected necrosis is: Many collections will remain sterile or resorb spontaneously.

Early severity stratification of acute pancreatitis is important to identify patients with the highest morbidity. The evaluation of the severity is one of the most important discussions on the AP handling. Log In Create Account. The extent of morphologic changes like necrosis and fluid collections is not directly proportional to the severity of organ failure.

Unable to process the form. Atlanta Classification of Fluid Collections The Revised Atlanta Classification discerns 4 types of xriterios fluid collections in acute pancreatitis depending on the content, degree of encapsulation and time. In the early stage, such a collection does not have a wall or capsule. Walled-off-necrosis 3 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.

Necrosis can be diagnosed with MRI, which of course should only be performed if it has direct clinical implications. Alguns autores, como Lecesne et al.

This patient underwent surgery. Since the diagnosis of acute pancreatitis is usually made on 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 vriterios ischemia.
