Pancreatic pseudocysts occur with pancreatitis. These are not truly cysts but are collections of pancreatic debris and fluid that may need to be treated with surgical drainage. The procedure involves opening the pancreatic cyst, cleaning out the cavity and sewing it to an opening in the small intestine, called cystjejunosotmy. This can be done laparoscopically or in an open fashion depending on the specifics of the case.
