Pancreatic pseudocysts that are 4cm in size and asymptomatic can be observed; cystic tumors that are asymptomatic can also be observed, and only if they are symptomatic will they require surgical treatment. Pancreatic pseudocysts are formed by the leakage and accumulation of pancreatic fluid. It is generally believed that pancreatic pseudocysts under 6cm in size and without symptoms can continue to be observed without treatment. If the pseudocyst develops complications such as bleeding and infection, or has symptoms such as abdominal pain and jaundice, or if the cyst continues to increase in size and multiple cysts are present, surgery may be an option. Cystic tumors of the pancreas usually grow slowly and most of them have no obvious symptoms. If there is abdominal pain, nausea and vomiting or touching the swelling in the abdomen, and the type of tumor is with the risk of malignant transformation, surgical treatment is needed. If you are not feeling well, please consult a doctor and complete the relevant examinations to make a clear diagnosis.
