Pancreatic pseudocysts. When and how should drainage be performed?

Area of Science:

• Gastroenterology
• Interventional Radiology
• Surgical Oncology

Background:

• Pancreatic pseudocysts require careful management, with traditional criteria for drainage no longer universally applicable.
• Advances in imaging and understanding of pseudocyst natural history necessitate updated management strategies.

Purpose of the Study:

• To review current concepts in pancreatic pseudocyst management.
• To outline indications for drainage and compare available therapeutic modalities.

Main Methods:

• Review of literature on pancreatic pseudocyst diagnosis and treatment.
• Analysis of factors influencing the choice between percutaneous drainage, endoscopic drainage, and surgery.

Main Results:

• Drainage indications now include symptoms, enlargement, complications (infection, hemorrhage, rupture, obstruction), and suspected malignancy.
• Percutaneous drainage is suitable for high-risk patients, immature, or infected pseudocysts.
• Endoscopic drainage is preferred for mature cysts in skilled hands, offering less invasiveness.
• Surgery remains the preferred option for complex cases like multiple, giant, or infected pseudocysts, and suspected malignancy.

Conclusions:

• The choice of pseudocyst management depends on patient condition, cyst characteristics, and available expertise.
• Percutaneous and endoscopic approaches are valuable alternatives to surgery, but further randomized trials are needed to establish optimal initial therapy.
