Overview
Acute pancreatitis may be classified according to the severity of disease into 2 subtypes: mild (interstitial or edematous) and severe (necrotizing or organ failure) pancreatitis.
Classification
The definitions of severity in acute pancreatitis according to the revised Atlanta classification are as follows.[1]
| Atlanta criteria (1993) | Atlanta Revision (2013) |
|---|---|
| Mild acute pancreatitis | Mild acute pancreatitis |
| Absence of organ failure | Absence of organ failure |
| Absence of local complications | Absence of local complications |
| Severe acute pancreatitis | Moderately severe acute pancreatitis |
| 1. Local complications AND/OR | 1. Local complications AND/OR |
| 2. Organ failure | 2. Transient organ failure (< 48 h) |
| GI bleeding (> 500 cc/24 hr) | Severe acute pancreatitis |
| Shock – SBP ≤ 90 mm Hg | Persistent organ failure > 48 h |
| PaO2 ≤ 60% | |
| Creatinine ≥ 2 mg/dl |
The revised Atlanta classification for acute pancreatitis classifies it as:[2][3][4][5][6][7][8][9]
- Mild pancreatitis (interstitial or edematous): inflammation of parenchyma of pancreas without local or systemic complications.
- Severe pancreatitis (necrotizing or organ failure): severe pancreatitis causing local and systemic manifestations.[10]
Acute pancreatitis is further distinguished clinically into:
- Early phase (1st week).
- Late phase (after the 1st week).
Subtypes of Acute Pancreatitis:
- Interstitial Edematous Pancreatitis
- ▸ Acute inflammation of the pancreatic parenchyma and peripancreatic tissues, but without recognizable tissue necrosis
- CECT criteria
- ▸ Pancreatic parenchyma enhancement by intravenous contrast agent.
- ▸ No findings of peripancreatic necrosis.
- Necrotizing Pancreatitis
- ▸ Inflammation associated with pancreatic parenchymal necrosis and/or peripancreatic necrosis
- CECT criteria
- ▸ Lack of pancreatic parenchymal enhancement by intravenous contrast agent
- ▸ Presence of findings of peripancreatic necrosis.
- Infected Pancreatic Necrosis:
- ▸ It should be considered in patients with necrotizing pancreatitis who deteriorate or fail to improve after 7–10 days of hospitalization.[1]
- ▸ It may be presumed by the presence of extraluminal gas on CECT or when fine-needle aspiration is positive for bacteria and/or fungi on Gram stain and culture.[11]
- ▸ Antibiotics are able to penetrate pancreatic necrosis (such as carbapenems, quinolones, and metronidazole) and may be useful in delaying or sometimes totally avoiding intervention.[12][13]
