Pancreatic plasma cysts are surgical diseases, some pancreatic cysts can subside on their own and can be treated conservatively, while most of the pancreatic cysts that cannot subside are treated by surgery. 1. Conservative treatment: pancreatic cysts without obvious symptoms can be treated conservatively first. 6cm and below cysts can be absorbed by themselves, so the size of cysts can be followed up by regular ultrasound. 2. Surgery: Partial resection of cyst and pancreas is usually applied to cystadenoma and some true cysts, while cystadenocarcinoma requires major resection of pancreas, such as pancreaticoduodenectomy or pancreatic coccygectomy. For example, intracystic drainage is usually applied to pseudocysts with thicker cyst wall, which is usually performed 2-3 months after the onset of the disease, when the cyst wall has matured and fibrosis, which is favorable for suturing. In addition, pancreatic plasma cysts can also be treated by percutaneous puncture replacement and drainage. If the patient has pancreatic plasma cysts, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease and standardize the treatment.
