Abstract:
ObjectiveTo investigate the value of endoscopic ultrasonography (EUS) in the diagnosis of pancreatic space-occupying diseases. MethodsA total of 85 patients with suspected pancreatic space-occupying diseases who were treated in The Second Affiliated Hospital of Jiaxing College from January 2015 to January 2017 were enrolled. Surgical pathological results or follow-up results were used as the gold standard for evaluating the value of EUS and EUS-guided fine needle aspiration (EUS-FNA) in the diagnosis of pancreatic space-occupying diseases. The chi-square test was used for comparison of categorical data between groups. ResultsEUS had an imaging detection rate of 96.7% (59/61), a specificity of 100% (24/24), and an accuracy rate of 97.6% (83/85) in the diagnosis of pancreatic space-occupying diseases; EUS had significantly higher detection rate and accuracy rate than abdominal ultrasound, computed tomography, and magnetic resonance imaging (detection rate: χ2=4.344, 3.873, and 15.445, all P＜0.05; accuracy rate: χ2=6.675, 8.685, and 17389, all P＜0.05). EUS-FNA had a detection rate of 81.8% (45/55) and an accuracy rate of 81.0% (47/58). Among the patients who underwent surgery to have pathological results, the overall coincidence rate of preoperative EUS-FNA was 84.2% (16/19). ConclusionCompared with conventional imaging examinations, EUS has a higher diagnostic accuracy for pancreatic space-occupying diseases, and EUS-FNA can further clarify the nature and pathological type of space-occupying lesions. EUS may help with the early diagnosis and treatment of pancreatic tumors.
