This study was conducted to investigate endoscopic features of superficial Barrett's esophageal adenocarcinoma (BEA) and elucidate differences between SSBE and LSBE.
MethodsFrom January 2006 to December 2016, 124 patients (131 lesions; SSBE: 101 patients, 101 lesions; LSBE [Barrett's esophagus with length of at least 3cm]: 23 patients, 30 lesions) who underwent endoscopic treatment or operation were enrolled, the endoscopic and histological findings were investigated.
Distribution of primary macroscopic types 0-I/0-IIa/0-IIb/0-IIc were: SSBE 14/49/4/34 and LSBE 5/10/9/6. In SSBE, 63/101 (67.2%) lesions were elevated, and 37/38 (97.4%) lesions of flat and depressed type were recognized as a reddish area and brownish area using NBI. In LSBE, 60.0% (9/15) were identified as a reddish area and 73.3% (11/15) were observed as a brownish area. The prevalence of complex macroscopic type (For example, IIa+IIb etc.) was: SSBE 33.7% and LSBE 46.7%, and of accompanied 0-IIb type was: SSBE 2.0% and LSBE 20.0%. SM invasion rate was: SSBE 19.4%, LSBE 18.8%in simple macroscopic type; SSBE 67.6%, LSBE 50.0% in complex macroscopic type. Histological mixed type was: SSBE 17.9%, LSBE 12.5% in simple macroscopic type; SSBE 44.1%, LSBE 42.3% in complex macroscopic type.
The almost BEA of SSBE could be distinguished by the elevated or reddish lesions. BEA of LSBE was associated with accompanied 0-IIb type, and complex macroscopic type with a focus on the high incidence of SM invasion rate and histological mixed type.
