Abstract:
Objective To analyse the negative predictive value of endoscopic ultrasonography (EUS)for detecting pancreatic cancer and to evaluate its clinical value of ruling out malignant cancer. Methods The medical records of patients who were referred to pancreatic EUS with suspected pancreatic cancer and normal EUS findings from January 2005 to December 2013 were reviewed. Moreover,the follow-up data were reviewed to evaluate whether the patient developed pancreatic cancer or other malignancy that could cause the abnormality mentioned above. The follow-up data were obtained by examining the inpatient/outpatient records as well as conducting brief telephone interviews. Results A total of 122 patients were in-cluded in our study. The follow-up data of 108 were accessible,and the mean follow-up period was 52. 4 months. One patient was histopathologically diagnosed as having pancreatic cancer 6 years after the proce-dure,and 107 other patients with a normal pancreatic EUS were free of pancreatic cancer as well as other malignancy during the follow-up period. The negative predictive value of pancreatic EUS was 99. 1%(107/108). Conclusion For patients with suspected pancreatic cancer but normal EUS findings,there is no need for further exploratory surgery. However,if there is a high suspicion of malignancy in the pancreas,a repeat-ed EUS is necessary in case of a false negative EUS result.
