 Usefulness of NBI for the early detection of superficial esophageal SCC has been reported. However, the detection sensitivity for small esophageal SCC by WL,NBI and iodine staining has never been reported.

 Patients and Methods : 32 lesions of small SCC(29 lesions of EP and 3 lesions of LPM, tumor median size : 3mm)treated by EMRC or ESD from May, 2005 to December, 2008 were enrolled in this study. The endoscopic pictures of WL, NBI and iodine were investigated retrospectively. The SCC was detected from the endoscopic findings such as protuberant, depression or color change by WL, well demarcated brown area by NBI and irregular unstained area by iodine, respectively. Small SCC was defined as a lesion 10mm or less in size.

 Results : Sensitivity of WL, NBI and iodine was 66%, 84% and 100%, respectively.

 Conclusion : NBI was useful for the detection of small esophageal SCC, however the sensitivity of NBI was lower than that of iodine staining. Therefore, iodine staining is still necessary for the surveillance in the high risk group for esophageal SCC.
