Pancreatic head cysts, this is generally to be considered as pseudocysts, mainly due to the complications of pancreatitis or after trauma. If the cyst is larger than six centimeters, with persistent epigastric pain, nausea and vomiting caused by pressure on the stomach, and difficulty in eating, this can be used for internal drainage: the surgical method is to use the cyst jejunum Roux-ne-Y anastomosis. If the cyst is located in the posterior wall of the stomach, the cyst can be directly anastomosed to the posterior wall of the stomach. With advances in medicine, internal drainage is now done laparoscopically or gastroscopically. If the cyst is relatively small and there are no obvious discomfort symptoms, there is no need for special treatment and therapy, and regular review is sufficient.
