Résumé

【Objective】 To compare the diagnostic value of endoscopic ultrasonography (EUS) with conventional imaging in pancreatic occupying lesions so as to provide guidance for the diagnosis of pancreatic occupying lesions. 【Methods】 We selected patients who underwent EUS in the Digestive Endoscopy Room of The First Affiliated Hospital of Xi’an Jiaotong University from September 2012 to December 2019 and were strictly screened by ultrasound endoscopists and diagnosed as pancreatic space-occupying lesions as the study subjects, and collected routine imaging examination results and related information and data of the patients (age, gender, tumor markers, blood amylase, urine amylase, and serum lipase) at the same time. We compared the sensitivity, specificity and accuracy of EUS and conventional imaging methods in the diagnosis of pancreatic space-occupying lesions, and evaluated their diagnostic value. 【Results】 A total of 188 cases were included, with more male ones than female ones. The age of patients in the tumor group was higher than that in the non-tumor group, and the levels of tumor markers serum CA-199 and CEA were significantly higher than those in the non-tumor group. The diagnostic sensitivity of pancreatic space-occupying lesions supported EUS (95.5%), which was significantly better than that of transabdominal ultrasound (54.4%), plain CT (57.1%), enhanced CT (75%), MRI (66.7%), PET-CT (72.7%) and other conventional imaging examination methods. The diagnostic accuracy of pancreatic space-occupying lesions supported EUS (91.5%), better than transabdominal ultrasound (58.3%), plain CT (57.1%), enhanced CT (74.6%), MRI (62.5%), and PET-CT (66.7%). The negative predictive value of the diagnosis of pancreatic space-occupying lesions supported EUS (76.7%), better than transabdominal ultrasound (27.9%), plain CT (22.9%), and enhanced CT (38.1%). 【Conclusion】 In the diagnosis of pancreatic space-occupying lesions, EUS is significantly better than conventional imaging methods such as transabdominal ultrasound, plain CT, enhanced CT, MRI, and PET-CT, and the negative predictive value of EUS is significantly better than that of transabdominal ultrasound, plain CT and enhanced CT.
