Isolated Mediastinal Pseudocyst of the Pancreas

Background: Mediastinal pancreatic pseudocyst is a rare complication of pancreatitis.Case characteristics: An 8-year-old boy with chest pain and shortness of breath.Computed tomography of chest showed a cystic mass in the mediastinum. The cyst aspiraterevealed high amylase and lipase levels, suggestive of pancreatic pseudocyst. Outcome:The patient gradually recovered after Roux-en-Y cystojejunostomy. Message: Cystojejunostomy is a viable treatment option for mediastinal pancreatic pseudocyst, especiallywith failure of medical therapy.

Development of the Asian EUS Group consensus in pancreatic pseudocyst drainage

Drainage of pseudocyst and walled-off pancreatic necrosis has traditionally been achieved by surgical means. Recently, there has been a progressive shift in paradigm to performing endoscopic drainage for these conditions. Endoscopic ultrasound (EUS)-guided drainage is the preferred approach for drainage of pancreatic pseudocyst. However, many controversies still exist on the optimal management and wide variations in techniques exist. There is a pressing need for establishment of a consensus for safe practices in EUS-guided pseudocyst drainage.
