Common benign tumors of the pancreas include cystic tumors of the pancreas (plasmacytoma, mucinous cystic tumor and intraductal papillary mucinous tumor), solid pseudopapillary tumors and non-functional islet cell tumors. These tumors have insidious onset, atypical symptoms, and lack of specific diagnostic methods, which can easily lead to misdiagnosis and delay in treatment. The most common cystic tumor of the pancreas is plasma cystadenoma (SCN), which occurs in the caudal part of the pancreas and is more common in females, with no malignancy and no obvious symptoms. Mucinous cystadenoma (MCN): accounts for 2.0-2.5% of pancreatic exocrine tumors, mostly occurring in the tail of the pancreatic body, more common in women, with a prevalence age of 49-63 yrs. MCN is characterized by large cysts, and the cut surface is mostly large unicompartmental or multicompartmental cysts filled with mucus. Intraductal papillary mucinous neoplasm of the pancreas (IPMN)): It accounts for 1-2% of pancreatic exocrine tumors. It is a mucus-secreting papillary tumor originating from the main pancreatic duct or its main branches, and has the potential for malignancy. Solid-pseudopapillary tumor of the pancreas (SPT): accounts for 0.17-2.17% of pancreatic exocrine tumors. It is mostly seen in young women and consists of both parenchymal and cystic tumor components. Non-functioning islet cell tumor: It accounts for about 15% of pancreatic endocrine tumors and is found in the head and tail of the pancreas. Diagnostic methods: Ultrasound is commonly used for screening examinations of pancreatic diseases, and it is difficult to make an accurate diagnosis because of the influence of gastrointestinal gas. Ultrasound endoscopy (EUS) can help distinguish pancreatic pseudocysts from solid tumors and improve the accuracy of diagnosis, while EUS-guided fine needle aspiration is a good method for differential diagnosis and interventional treatment of pancreatic diseases. CT and MRI are the most common and effective examination methods for pancreatic diseases. The advantages of thin layer multi-row spiral CT are: less invasive, accurate localization, not affected by the gastrointestinal tract, and more helpful to determine the nature of the tumor; MRI can not only clarify the location of the lesion, but also has good diagnostic value for cystic lesions of the pancreas connected with the main pancreatic duct. The relationship between pancreatic tumor and surrounding blood vessels, bile ducts and pancreatic ducts can be shown, which can provide guidance for surgical resection. Treatment: Currently, it is recommended that benign pancreatic tumors should be treated with surgery as early as possible. The reason is that all benign pancreatic tumors, except SCN, have the potential to become malignant. For SCN, if a pathological diagnosis can be obtained preoperatively, and the tumor diameter is <3 cm and there are no clinical symptoms, close follow-up observation can be adopted and surgery can be temporarily withheld. Other tumors, once diagnosed or highly suspected preoperatively, should be surgically explored combined with intraoperative frozen pathology to determine the extent of resection. Surgical procedures include tumor removal, pancreatic segmental resection, pancreatic head resection with preservation of duodenum, pancreaticoduodenectomy and tail resection of pancreatic body. The efficacy of laparoscopic tumor removal and distal pancreatic resection is significantly better than that of traditional open surgery. Laparoscopic pancreatic tumor removal is mainly suitable for benign lesions with a diameter of 2 cm or less and distant from the main pancreatic duct and important blood vessels. Laparoscopic distal pancreatic resection is mainly applicable to benign lesions in the tail of the pancreatic body, and distal pancreatic resection with preservation of the spleen is advocated under the premise of ensuring negative incision margins. At present, laparoscopic surgery cannot completely replace traditional open surgery, and reluctantly performing laparoscopic surgery will increase the risk of surgery and affect the outcome. In our department, a 27-year-old female patient was admitted to the hospital with a mass in the tail of the pancreatic body found by ultrasound during physical examination. Enhanced CT of the abdomen revealed a 3 cm diameter cystic solid mass in the tail of the pancreatic body, with moderate enhancement of the solid part in the arterial phase. Tumor markers were not significantly abnormal. Laparoscopic resection of the tail of the pancreatic body with preservation of the spleen was performed. The postoperative pathology was diagnosed as SPT, and the patient recovered well after surgery and was discharged 8 days later.
