Overview
A pancreatic pseudocyst is a circumscribed collection of fluid rich in amylase and other pancreatic enzymes, blood and necrotic tissue typically located in the lesser sac. It has a non-epithelialised lining made of granulation tissue and hence the name pseudocyst (pseudo - false). By contrast, true cysts have an epithelial lining. This is typically a complication due to increased pressure in the pancreatic duct (e.g. stenosis, calculus, protein plugs) or pancreatic necrosis following an episode of acute pancreatitis, but may also occur following abdominal trauma. [1] Pancreatic pseudocyst generally complicates the course of chronic pancreatitis in around 30-40% of the patients.[2]
Historical Perspective
Classification
| TYPE | DESCRIPTION |
|---|---|
| I | <5cm, without symptoms, complication and neoplasia |
| II | Suspected cystic neoplasia |
| III | Location is Uncinate process
IIIa- Pseudocyst communicates with the pancreatic duct. IIIb- Pseudocyst does not communicate with pancreatic duct. |
| IV | Location of Pancreatic Pseudocyst is Head, Neck and Body.
IVa- Communication exist between pseudocyst and pancreatic duct (1) IVb- Distance from the cyst to the gastrointestinal wall is <1cm (2) IVc- Neither 1 nor 2 |
| V | Location of Pancreatic Pseudocyst is Tail.
Va- Splenic vein involvement or upper gastrointestinal bleeding Vb- Distance from the cyst to the gastrointestinal wall is <1cm without splenic vein involvement or upper gastrointestinal bleeding[3] |
