title: [The application of intraoperative ultrasonography in the diagnosis and therapy of insulinoma].
abstract: OBJECTIVE
  To analyze the value of intraoperative ultrasonography (IOUS) in the diagnosis and therapy of insulinoma.
  
  
  METHODS
  From January 2000 to December 2007, the application of intraoperative ultrasonography used in 44 cases with insulinoma who came from department of general surgery, First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 19 males and 25 females in the group. Every case accepted operation and examination of IOUS.
  
  
  RESULTS
  Tumor was accurately located and its adjacent structure was also clear by IOUS in 43 cases, the other one was islet cell hyperplasia, the detection rate of tumor was 100%. The complications: one case occurred pancreatic fistula, one occurred pancreatitis, and there was no biliary fistula and hemorrhage.
  
  
  CONCLUSIONS
  Presently, IOUS is one simple and effective method to local insulinoma, and it could improve the success rate of operation and reduce complications.
