Pancreatic serous cystic tumor: A clinical analysis of 43 cases

Objective To summarize the diagnosis and treatment of pancreatic serous tumor. Methods Imaging and laboratory test data, surgical procedures, complications and prognosis of 43 patients with pancreatic serous tumor admitted to our hospital from January 2008 to October 2012 were retrospectively analyzed. Results Of the 43 patients, some underwent abdominal B ultrasound, pancreatic enhancement CT and peripheral blood tumor marker examination, some underwent MRI, ERCP and EUS. The tumor was located in pancreatic head, body and tail in 14 patients (32.6%), 21 patients (48.9%) and 8 patients (27.6%), respectively. Of the 43 patients, 40 (93%) underwent surgical operation and 3 (7%) diagnosed by image examination received regular reexamination, 6 (15%) underwent pancreaticoduodenectomy, 18 (45%) underwent pancreatic body and tail resection, 6 (15%) underwent pancreatic middle resection. 10 (25%) underwent local resection. The operation time was 60-400 min with an intra-operative blood loss of 20-400 ml. Pancreatic fi stula was found in 8 patients (20%) after operation, 1 patient (2.5%) died in perioperative period due to massive bleeding in abdominal cavity, wound infection occurred in 1 patient(2.5%). No complications occurred such as abdominal infection and delayed gastric emptying. The patients were followed up for 3-16 months, during which no recurrence and metastasis were observed. Conclusion Pancreatic serous cystic tumor is a rare and benign lesion. Abdominal B ultrasound, CT and MRI can differentiate it from mucinous tumors. Rational treatment modalities should be selected according to the lesion situation.
