- Abstract: Objective To analyze the value of endoscopic ultrasonography(EUS)combined with abdominal computed tomography(CT)in differentiating diagnosis of benign and malignant pancreatic space occupying lesions.Methods From May 2020 to May 2023,among of 120 patients with pancreatic space occupying lesions were selected,41 benign cases were included in the benign group and 79 malignant cases were included in the malignant group.The results of EUS,abdominal CT,combined detection and pathological detection were compared,the differentiating value of EUS,abdominal CT and combined detection in benign and malignant pancreatic space occupying lesions was investigated on the basis of receiver operator characteristic curve(ROC curve).Results Compared with the benign group,the proportion of lesion diameter＞2 cm was higher in the malignant group(P＜0.05).In the benign group,including 7 cases of mucinous cystadenoma,15 cases of neuroendocrine tumors,8 cases of serous cystadenoma,5 cases of papillary mucinous neoplasm,6 cases of solid pseudopapilloma of the pancreas;In the malignant group,including 60 cases of pancreatic cancer,11 cases of pancreatic ductal adenocarcinoma,and 8 cases of adenocarcinoma of the bile duct.EUS,abdominal CT and combined detection were used to accurately diagnose malignant pancreatic space occupying diseases in 68,53 and 75 cases.Malignant was included as positive,benign as negative,and ROC curve was drawn to analyze the differentiating value of EUS,abdominal CT and combined detection in pancreatic space occupying diseases,area under the curve(AUC)was 0.833,0.653,0.913 respectively,and sensitivity was 86.08%,67.09%,94.94%respectively,the specificity was 80.49%,63.41%,87.80%respectively,and the combined detection was the highest.Conclusion The proportion of malignant pancreatic space occupying lesions with diameter＞2 cm is higher,and EUS combined with abdominal CT has a good value in differentiating benign and malignant pancreatic space occupying lesions,which can provide a good foundation for early diagnosis and treatment of the disease.
