 The aim of this study is to clarify the factors that make ESD for gastric cancer with ulcer scar difficult.

 1,489cases of early gastric cancer were treated by ESD from January 2004 to March 2012, and 165cases of early gastric cancer had ulcer scar.

 The patients were divided into two groups, complete resected group(Enbloc without injure in the specimen, n=143)and incomplete resected group(piece meal or enbloc resection with injure in the specimen, n=22).

 The incomplete resection rate of lesser curvature lesions and the other site was 19%(17/91)and 9%(5/74), respectively(p=0.025). The incomplete resection rate of 31mm or more(contraindication)and 30mm or less lesions(expanding indication)was 29%(10/34)and 9%(12/131), respectively(p=0.020).

 R0 resection is necessary for the curative endoscopic treatment. And, the R0 resection rate of 30mm or less and with ulcer group was 91%. The improvement of R0 resection rate for this group is necessary.
