COMPARISON OF ENDOSCOPIC ULTRASOUND AND COMPUTED TOMOGRAPHY FOR EVALUATION OF PANCREATIC MASS LESIONS ASSUMING HISTOPATHOLOGY AS GOLD STANDARD

Abstract

Background-Diagnostic imaging is an important tool to evaluate pancreatic neoplasms. Accurate detection and staging are essential for ensuring appropriate selection of patients who will benefit from surgery and for preventing unnecessary surgeries in patients with unresectable disease. Ultrasound (US), multidetector computed tomography (MDCT) with multiplanar reconstruction and magnetic resonance imaging (MRI) can help to do a correct diagnosis.

Methods- Hospital based cross-sectional and quantitative study. Patients with suspected pancreatic mass lesions referred to Department of Radiodiagnosis and Modern Imaging and to Department of Gastroenterology for MDCT and EUS respectively.

Results- EUS sensitivity was 98.00%, specificity was 75.00% and by CT scan sensitivity was 93.00%, specificity was 88.00% for mass detection. EUS sensitivity was 88.00%, specificity was 72.00% and of CT scan sensitivity was 76.00%, specificity was 100.00% in detection of vascular involvement. EUS sensitivity was 86.00%, specificity was 74.00% and by CT scan sensitivity was 92.00%, specificity was 100.00% for detection of lymphadenopathy.

Conclusion- In conclusion, our results showed that CT with pancreas protocoland EUS correlate moderatelywell in terms of mass detection, masssize, vascular involvement and lymphadenopathy.
