Comparison of Endoscopic Ultrasonography and Computed Tomography for Staging of Pancreatic Cancer


This research proposal aims to compare the accuracy of Endoscopic Ultrasound (EUS) Computed Tomography (CT) in pre-operative staging of pancreatic cancer. Quantitative research design will be employed with a sample of 120 subjects to determine the accuracy of both the methods. Numerous studies and researches show that a combination of multiple imaging modalities is often used in the staging and diagnosis of pancreatic cancer. However, the techniques that are most widely and commonly used in this regard include computed tomography (CT), and endoscopic ultrasound (EUS). Many researchers have also proved the accuracy percentage of all these imaging modalities. Thus, this research proposal primarily focuses on finding out which imaging is accurate of all, and which one has the greatest diagnostic accuracy. After analyzing and studying the results provided by numerous researches in this regard, it has been proved that trans-abdominal ultrasound is able to provide a diagnostic accuracy of 82 to 86% and a sensitivity of 86 to 89% for diagnosing malignant pancreatic head tumours. Moreover, the diagnostic yield cannot be improved by combining the two modalities in equivocal cases. In addition, the comparison of these modalities proves that EUS or Endoscopic Ultrasound is superior to CT (Computed Tomography) when it comes to the detection of small tumours.

Comparison of Endoscopic Ultrasonography and Computed Tomography for Staging of Pancreatic Cancer


The main rational behind this study is that with an increasing issue about the accuracy of the methods used for staging of pancreatic cancer, it is needed to find out and examine that what is the most accurate method among Endoscopic Ultrasonography and Computed Tomography. Moreover, a large number of recent researches have examined that Computed Tomography itself results in causing cancer, and the technique is less accurate than Endoscopic Ultrasonography. So, this research's main rational is to analyze the related studies, and to draw conclusions accordingly. The primary aim of this study is to compare the accuracy of Endoscopic Ultrasound (EUS) and Computed Tomography (CT) for the staging, detection, and resectability of pre-operative pancreatic cancer.

Rational, Aims and Objectives

The aim of this research is to determine the best methods of detecting pancreatic tumour by comparing Endoscopic Ultrasound and Computed Tomography. The research will evaluate the diagnostic yield of the two methods under different stages to determine the most accurate ...
