BACKGROUND: In Japan, superficial Barrett's adenocarcinoma (SBA) still remains unclear in the endoscopic features and treatment outcome. PATIENTS&METHOD: We conducted a questionnaire survey to 10 Japanese expert endoscopists, collecting data of 168 patients with 175 SBA. RESULTS: Of 175 SBA, 157 (90%) were a reddish lesion, 133 (76%) were located on the right or anterior side, and 166 (95%) were detected by white light endoscopy (WLE). Magnified image enhanced endoscopy (IEE) was useful to diagnose lateral tumor extension accurately in 42 (60%) of 70 SBA being invisible by WLE. Of 144 SBA being adjacent to SCJ, 75 (52%) demonstrated subsquamous extension. Magnified IEE was useful to visualize subsquamous extension in ten (45%) of 22 SBA with the subsquamous extension being invisible by WLE. SBA removed by Endoscopic resection, ER (n=136, 78%). No patient died of SBC after ER for mucosal carcinomas during observation period longer than 2 years. CONCLUSION: Endoscopic characteristics of SBA were a reddish area located on the anterior to right side. IEE deemed useful for diagnosing the lateral tumor extension and subsquamous tumor extension. ER for mucosal carcinoma provided excellent prognosis. |
