Secondarily,  we describe the prevalence and clinical significance of jejunal polyposis. Patients and methods  This is a single center, prospective study of 62 patients with familial adenomatous polyposis. Duodenal polyposis was classified according to Spigelman and ampullary adenomas were identified. Patients with Spi- gelman III and IV duodenal polyposis underwent balloon as- sisted enteroscopy.

Author information Abstract BACKGROUND AND STUDY AIMS: Several studies have evaluated the utility of double-balloon enteroscopy (DBE) and capsule endoscopy (CE) for patients with small-bowel disease showing inconsistent results. The aim of this study was to determine the sensitivity and specificity of overtube-assisted enteroscopy (OAE) as well as the diagnostic concordance between OAE and CE for small-bowel polyps and tumors. PATIENTS AND METHODS: We conducted a systematic review and meta-analysis of studies in which the results of OAE were...
