Pancreatic cysts have different indications for surgery depending on the nature of the cyst. When non-neoplastic pancreatic cysts are complicated with compression symptoms, surgical treatment should be considered. If the cysts are pseudocysts and larger than 6cm or are neoplastic cysts, surgical treatment is required. 1. Non-tumor pancreatic cysts: If the patient has non-tumor pancreatic cysts, there is no need for treatment when there are no obvious symptoms, and observation is the main concern. If pancreatic cyst occurs compression symptoms, such as compression of pancreatic head, bile duct causing jaundice symptoms, or repeated complication of pancreatitis, it should be treated with surgery. 2. Pseudopancreatic cysts: most of the patients’ pseudocysts can be absorbed by themselves with time, if the patients’ pseudopancreatic cysts are larger than 6cm in diameter and have mature and thicker cyst wall, and the cysts do not decrease in size after 4~6 weeks of observation and instead show progressive enlargement, then they need to be operated in time. 3. Tumorous pancreatic cysts: Because of the possibility of malignant transformation of tumorous pancreatic cysts such as mucinous cystadenoma, once diagnosed, surgical resection is required. Pancreatic cysts need to be treated surgically according to the nature and size of the cysts and the individual’s condition, and it is recommended that patients should determine the treatment method under the doctor’s diagnosis.
