Most patients with pancreatic cysts are not seriously ill, but they need to be analyzed in conjunction with relevant examination and laboratory results and reviewed regularly. Pancreatic cysts are broadly defined and are mainly divided into tumor cysts and non-tumor cysts. Non-neoplastic cysts are also divided into true cysts and pseudocysts. Pseudocysts are more common in clinical practice. Patients mostly suffer from pancreatic trauma, pancreatitis or surgery, resulting in the exudation of pancreatic fluid and then wrapping and accumulation, finally forming a tissue shaped like a cyst, but not a real tumor. If the patient has no physical discomfort and is not accompanied by abnormal blood and urine amylase, blood and urine lipase, liver enzymes, bilirubin and other indicators, only regular review of abdominal ultrasound and other related examinations are needed for observation. However, if it is accompanied by nausea, vomiting, abdominal discomfort and other abnormal laboratory indicators, it is necessary to promptly visit the hospital’s gastroenterology department to assess the severity of the condition and provide treatment. If the pancreatic cyst is large and presses on the neighboring organs, causing compression symptoms, surgery is required, although there is no short term risk of life.
