Treatment depends on the size of the pseudocyst and whether it is causing symptoms. Many pseudocysts go away on their own. Those that remain for more than 6 weeks and are larger than 5 cm in diameter often need treatment.
Possible treatments include:
Drainage through the skin using a needle, usually guided by a CT scan
Endoscopic-assisted drainage using an endoscope (a tube containing a camera and a light that is passed down into the stomach)
Surgical drainage of the pseudocyst, which involves making a connection between the cyst and the stomach or small intestine. This may be done using a laparoscope.
The outcome is generally good with treatment. It is important to make sure that it is not a pancreatic cancer that starts in a cyst, which has a worse outcome.
