In a prospective study, similar numbers of FDRs of patients with CRC assigned to undergo CCE or colonoscopy agreed to participate, but most preferred to undergo colonoscopy. CCE was as effective as colonoscopy in detecting significant lesions; it could be a valid rescue strategy for subjects who reject screening colonoscopy. ClinicalTrials.gov number: NCT01557101.

Endoscopic ultrasonography-guided fine-needle aspiration cytology (EUS-FNA) may provide full-thickness biopsies, adequate for cytology and histology. In the present case report, we describe the first cases of a rare well-differentiated squamous esophageal carcinoma (verrucous esophageal cancer), finally diagnosed by EUS-FNA using a large FNA needle after several upper endoscopies with biopsies negative for malignancy. In this report, we highlight the usefulness of this procedure and EUS features in the diagnosis of suspicious esophageal lesions with negative endoscopic biopsies for malignancy.
