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.

Interstitial pancreatitis Morphologically there are 2 types of acute pancreatitis – interstitial or oedematous pancreatitis and necrotizing pancreatitis. This patient died on day 5 due to severe SIRS and multiple organ failure.

Rarely only the pancreatic parenchyma. In these cases MRI can be of additional value. Med Intensiva ; The patient became septic and a percutaneous drainage was performed. The extent of morphologic changes like necrosis and fluid collections is not directly proportional to the severity of organ failure. The Sperman coefficients of correlation were calculated in order to associate the different scales.

EmBalthazar et al. Therefore, to have or not an advanced Balthazar does not necessarily represent a serious pancreatic disease or a systemic inflammatory response, and on the other hand to have a slight disease by means of clinical and biochemical criteria does not mean a lower degree on the tomographic Balthazar classification. On day 18 an incomplete wall is present, but we can assume that in a couple of days this will be a walled-of-necrosis with a complete wall. Notice how the greater part of the pancreatic body and tail no longer enhances indicating necrotizing pancreatitis arrows.

Fifty per cent of the patients had acute severe pancreatitis according to the Atlanta criteria. On day 5 this collection can be diagnosed as probable acute necrotic collection.

Reproducibility in the assessment of acute pancreatitis with computed tomography

UK guidelines for the management of acute pancreatitis. A critical evaluation of laboratory tests in acute pancreatitis. The BISAP is a more-recent score than the older Ranson’s Criteria, and does not require data points from 48 hours into a patient’s hospital admission.


Or create a new account it’s free. Rev Esp Enferm Dig ; 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.

Necrosis of peripancreatic tissue can be vary difficult to diagnose, but is suspected when the collection is inhomogeneous, i. Log in Sign up. To all the Gastroenterology medical staff of Mexico’s General Hospital for their invaluable support.

Pancreas – Acute Pancreatitis 2.0

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. There were no complications and the diagnosis of mild pancreatitis was made. Alguns autores, como Lecesne et al.

Based on CT alone it is sometimes impossible to determine whether a collection contains fluid only or a mixture of fluid and necrotic tissue.

This patient had no fever or signs of sepsis. It was not possible on our second study to measure it on all of the patients, but in a 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 pancreatitie not a tomographic study in patients with slight AP.

Scroll through the images. It must be pointed out that the optimal time to perform the tomographic study is 48 to 72 hours after the symptomatology has begun. Morphologically there are 2 types of acute pancreatitis – interstitial or oedematous pancreatitis and necrotizing pancreatitis.

A Pseudocyst is a collection of pancreatic juice or fluid enclosed by a complete wall of fibrous tissue It occurs in interstitial pancreatitis and balthwzar absence of necrotic panreatitis is imperative for its diagnosis. The characteristics of the patients that were included on the study are shown on table I.


An important consideration was the impossibility to correlate the tomographic finds with the serum concentration of reactive C proteins, which is considered until the present moment the best prognosis indicator of AP. Ao compararmos os dados obtidos pelos observadores 1 e 2, respectivamente em momentos diferentes reprodutibilidade intra-observadornotamos: Check for errors and try again.

There are 3 subtypes of necrotizing pancreatitis: Morphologic severity of acute pancreatitis d pancreatic parenchymal necrosis can only be reliably assessed by imaging 72 hours after onset of symptoms. The necrosis also involves the peripancreatic tissue.

Pseudocyst After 4 weeks in interstitial pancreatitis. On day 3 there is no enhancement of the pancreas, consistent with necrosis. Here another case of interstitial pancreatitis without necrosis.

On this study we found that in our hospital service we have a low frequency of the disease. The patient underwent surgery and the collection was found to consist of necrotic debris, which was not appreciated on CT, hence this was a walled-off-necrosis and not a pseudocyst.

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. The body and tail of the pancreas do not enhance. On a follow-up scan the collection in the right anterior pararenal space increased in size. Normal enhancement of the entire pancreas. The AP diagnosis was performed to the patients that had at least 2 of the 3 following criteria: Indications for intervention in necrotizing pancreatitis are: 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.
