Factors predictive of the healing of pancreatic pseudocysts treated by percutaneous evacuation

Pseudocyst formation is a well-known complication of pancreatitiswhich develops over 1 to 4 weeks in approximately 15% of patients. Nearly one-third of pancreatic pseudocystsresolve spontaneously ; however, if there is no resolution within six weeks, evacuation must be performed.The aim of this study was to prospectively assess the reliability of the following: etiology ; location ; amount of pseudocyst liquid ; and concentrations of certain biochemical parameters (LDH, glucose, proteins, sodium, potassium, bilirubin, lipase and amylase) in the pseudocyst content and patients' serum, in termsof the efficacy of ultrasound-guided percutaneous evacuation as a therapeutic approach. METHODOLOGY:Pseudocyst fluid was obtained by ultrasound-guided percutaneous evacuation in 67 patients, with a historyof pancreatitis and pancreatic pseudocysts larger than five centimeters in diameter, with a matured membraneouswall that persisted for more than six weeks. RESULTS: There is a prognostic value associated with thelocation of the pseudocyst, the amount of pseudocyst liquid and the concentration of proteins, potassium, lipase and amylase in the evacuated material. CONCLUSION: Analysis of the aforementioned parameters providesan early forecast of the outcome of percutaneous evacuation.
