21Cases Islet Cell Tumor Clinical Analysis

Objective: To summarize the diagnosis and surgical treatment of islet cell tumor.Methods: To collect21cases of islet cell tumor from Jan,2005to Dec,2010admitted inthe first affiliated hospital of Xinjiang Medical University. To analyze the clinicalmanifestations, inspection methods and treatment effects retrospectively. Results: Of the21patients,20patients were insulinomas and the remaining1patient was nonfunctionalislet cell tumor. All the patients of insulinoma had Whipple’s triad, The patients ofnonfunctional islet cell tumor had no specific symptoms at the time of diagnosis. Thepositive rates of B-ultrasound, CT, MRI and ASVS were83.3%,64.7%,66.7%and100%respectively.21cases received operation,20cases (95.2%)were single, l case (0.5%)were multiple,3case was located in the head of the pancreas,5cases in the neck,10casesin the body,6cases in the tail. The main surgical procedures includes intraoperative B toexceed the islet cell tumor accurate guide enucleation in14cases, pure islet cell tumorenucleation in3, spleen and pancreatic tail resection body in1, pancreatic islet cell tumorresection and bowel anastomosis in1, laparoscopic pancreatic islet cell tumor resection in1, pancreticoduedenectomy in1. Conclusions：Islet cell tumor mainly includes functionalislet cell tumor and nonfunctional islet cell tumor, exact diagnosis is islet cell tumorpositioning the key for successful operation. For islet cell tumor, the surgical treatmentmainly depends on the tumor location, size and benign or malignant.
