Superficial esophageal cancer observed with the PillCam ESO 2 in combination with the flexible spectral imaging color enhancement system.

摘要

PillCam ESO2 (Given Imaging, Yoqneam, Israel), a second-generation esophageal capsule endoscope, is expected to provide an excellent visualization and consequently a higher rate of detection of esophageal lesions.1 However, the diagnostic yield of capsule endoscopy for esophageal neoplastic lesions against a high-quality charge coupled device (CCD) endoscope with the Hi-Vision system (Olympus Medical Systems, Tokyo, Japan) is still controversial.2 The flexible spectral imaging color enhancement (FICE) system is a new dye-less imaging technique that enhances mucosal and vascular patterns, and this computed virtual chromoendoscopy is superior to the images obtained with conventional endoscope.3 FICE has also been available for capsule endoscopy of the small intestine and this system possibly improves the detection of the lesion.4 We encountered the impressive case of a 63-year-old man with superficial cancer of the lower esophagus that was examined with the combined use of PillCam ESO2 and FICE.
