Background and aims:To evaluate the advantages of endoscopic ultrasound (EUS) in the
assessment of detailed structures of pancreatic cystic lesions (PCLs) compared to computed
tomography (CT) and magnetic resonance imaging (MRI).
Methods: This prospective cohort study was conducted in Tropical medicine department,
Zagazig university hospitals and in Internal medicine department at Kasr Al Aini Hospitals,
Cairo University, in the period between March 2018 and March 2020. The study included 72
patients with PCLs, 29 were males and 43 were females, there ages ranged from 25 to 75 years.
All cases were subjected to the following careful history taking, thorough clinical examination,
laboratory investigations (CBC, LFTs, KFTs, Coagulation profile, serum amylase, serum CA
19.9), imaging (CT and/or MRI abdomen), endoscopic ultrasound examination and EUS-FNA
biopsies using the 22G or 19G needle.
Results:Validity of abdominal CT/MRI imaging, EUS, cytopathology and EUS with
cytopathology was calculated using diagnostic performance depend on sample 2x2 contingency
tables generation. Sensitivity, specificity, PPV, NPV and accuracy and their corresponding 95%
CI were calculated. P-value < 0.05 was considered statistically significant, p-value < 0.001 was
considered highly statistically significant, and p-value ≥ 0.05 was considered statistically
