 Objective:This study aimed to evaluate the association between profile views during BE(barium enema)and depth of SM(submucosal)invasion in early CRC(colorectal cancer)in T1 stage.

 Methods:We retrospectively enrolled patients with endoscopically or surgically resected CRCs with SM invasion, evaluated using BE in the past 10 years. We measured the horizontal and vertical widths of the deformity under profile view of BE at the site of the CRC and calculated the most appropriate cutoff values for discriminating SM invasion depth of ≥1,800μm from that of <1,800μm.

 Results:In 133 T1 CRCs, the horizontal deformity width(r=0.6657, p<0.01)and vertical deformity width(r=0.5197, p<0.01)showed moderate correlations with the depth of SM invasion. In order to predict the SM invasion depth of >1,800μm, the most appropriate cutoff value of the horizontal deformity width was 4.5mm with an accuracy of 82.0%, whereas that of the vertical deformity width was 0.5mm with an accuracy of 79.7%. Lymphovascular invasion was more common in CRCs with a horizontal width deformity of >4.5mm than in those with a deformity of <4.5mm(p<0.05).

 Conclusions:The horizontal and vertical widths of the deformity on profile view during BE may be useful for predicting the SM invasion depth.
