Assessment of lesions protruding from the duodenal wall is difficult. Upper gastrointestinal (GI) endoscopy and computed tomography (CT) are not able to completely distinguish between different tumors and guide their subsequent management. Endoscopic ultrasonography (EUS) has a significant diagnostic yield in this context. EUS is able to accurately diagnose duodenal lesions, perform a biopsy if considered useful, guide the approach for resection and provide appropriate follow-up. SETs reported during upper GI endoscopy are more commonly cysts, polyps, lipomas, Brunner’s gland adenoma, ectopic pancreas, gastrointestinal stromal tumors (GISTs) or neuroendocrine tumors (NETs). In addition, although more rarely, adenocarcinomas and lymphomas can be identified. EUS should be performed for any duodenal lesion larger than 1 cm that lacks the endoscopic characteristics of a cyst or a lipoma.","PeriodicalId":133344,"journal":{"name":"Endoscopy in Small Bowel Diseases","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125357493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of radiological imaging techniques, which do not significantly disturb patients’ comfort and safety, attempts to obtain an adequate diagnosis and valuable information. The aim is to determine the capabilities and potential of ultrasound, computed tomography (CT), diffusion-weighted imaging (DWI), and contrast-enhanced magnetic resonance (MR) enterography to establish the diagnosis and to evaluate the severity and activity of intestinal inflammation. Conventional ultrasound is a suitable orientation method in the initial evaluation of patients with Crohn’s disease. At the same time, contrast-enhanced MR enterography provides an excellent assessment of disease activity, as well as the complications that accompany it. Contrast-enhanced MR enterography, combined with DWI, allows for excellent evaluation of disease activity and problems or difficulties following it. The examination can be repeated, controlled and can monitor patients with this disease.","PeriodicalId":133344,"journal":{"name":"Endoscopy in Small Bowel Diseases","volume":"17 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114033921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
