PANCREATIC TUMORS - COMPARISON OF DUAL-PHASE HELICAL CT AND ENDOSCOPIC SONOGRAPHY

OBJECTIVE, The purpose of this study was to compare dual-phase helical CT and endosonography for the diagnosis and staging of pancreatic tum ors. SUBJECTS RND METHODS. Thirty patients with suspected pancreatic t umors underwent endosonography and dual-phase helical CT. A pathologic diagnosis was obtained in all cases with surgery (n = 23) or biopsy ( n = 7), resulting in 7,7 neoplasms. Dual-phase helical CT and endosono graphic findings were correlated with surgical and pathologic findings to determine diagnosis and resectability of pancreatic tumors. RESULT S. Overall diagnostic sensitivity was 92% for dual-phase helical CT an d 100% for endosonography (p = .45). Overall accuracy for staging of p ancreatic tumors was 93% for both dual-phase helical CT and endosonogr aphy. Overall accuracy for predicting resectability was 90% for both d ual-phase helical CT and endosonography. Accuracy of predicting unrese ctability was 100% for dual-phase helical CT and 86% for endosonograph y (p > .80). Differences were not considered statistically significant . CONCLUSION. Dual-phase helical CT and endoscopic sonography do not d iffer significantly for diagnosis and assessment of resectability of p ancreatic tumors.
