ABSTRACT
Objective To evaluate the diagnosis and application values of endoscopic ultrasonography (EUS) with micro-probe in duodenal lesions.Methods Clinical data of 37 patients with duodenal lesions and underwent EUS with micro-probe were analyzed retrospectively.All lesions were treated with endoscopic mucosal resection or surgical resection to get the pathological diagnosis.The diagnostic accuracy of EUS with microprobe and endoscopic biopsy was analyzed respectively.Results The overall diagnosis accuracy of EUS with micro-probe on duodenal lesions was 78.38％ (29/37),with a higher diagnostic rate in duodenal lipoma 4/4and duodenal adenomas 10/12 than in early duodenal cancer 2/4 or inflammatory hyperplasia 3/8.The overall diagnostic accuracy of biopsy on duodenal lesions was 40.54％ (15/37),with a higher diagnosis rate on duodenal carcinoid 1/1 and adenoma 7/12 than on duodenal stromal tumor 1/10 and lipoma 1/4.Conclusion Pathological evaluation of endoscopic biopsy sample is not a golden standard for the diagnosis of duodenal lesions,while EUS with micro-probe has better diagnostic and application value.
