Pancreatic cysts do not necessarily require spleen removal. There are pseudocysts and true cysts. Most pseudocysts can be self-absorbed without special treatment. Surgical treatments such as internal drainage or external drainage are performed only when the pseudocysts are too large and pressure symptoms occur or complications such as bleeding and infection occur, but the surgical treatment of pancreatic pseudocysts generally does not require spleen removal. True cysts include congenital true cysts, retention cysts and pancreatic cystic tumors. Among them, when the cysts are located in the tail of the pancreas and the splenic blood vessels are closely adhered and cannot be separated, or when malignant pancreatic cystic tumors invade the spleen, splenectomy is required, but not all pancreatic cysts need to be treated with splenectomy. Patients with pancreatic cysts should go to the hospital in time and choose the appropriate treatment under the guidance of the doctor.
