Abstract    Objective    To investigate the diagnosis and treatment of serous cystadenoma of the pancreas.  Methods The clinical data of 20 patients with serous cystadenoma of the pancreas which were admitted into the First Hospital of China Medical University from April 2006 to April 2012 were retrospectively analyzed. Results    There were 6 males (30%) and 14 females(70%).Tumors were present in the pancreatic body and tail in 15 cases,in the pancreatic head in 5 cases.The mean diameter of the tumor was 5.7cm. The clinical manifestations of upper abdominal discomfort 15 cases,abdominal pain and bloating 8 cases, including mild nausea 2 cases, jaundice 1 case. Ultrasound and CT lesion detection rate was 100%, the ultrasound localization rate 83.3%, CT 100%. All 20 patients received surgical resection. Duodenum-preserving pancreatic head resection in 1 case,pancreaticoduodenectomy was performed in 4 cases, central pancreatectomy in 2 case, distal pancreatectomy with splean in 7 cases, and spleen preserving distal pancreatectomy in 6 cases. Postoperative pancreatic fistula and intra-abdominal infections developed in 5 cases,Fistula was healed by conservative therapy in all these 5 cases. No perioperative deaths, postoperative followed up from 12 to 79 months,The median survival time 39.5 months.Found no recurrence. Conclusions    Ultrasound and CT was main imaging examination for serous cystadenoma of the pancreas,and Accurate early detection and positioning lesions,Surgical resection should be adopted for serous cystadenoma of the pancreas with uncertain malignancy. Surgery should be benign surgical principles, try to retain the organs, reduce surgical trauma, serous cystadenoma prognosis is good.
