 Objective:This investigation aimed to determine the invasion depth of colorectal epithelial neoplasms using barium enema examination(BE), conventional endoscopy(CE), magnifying narrow-band imaging endoscopy(M-NBI), and magnifying chromoendoscopy(MC).

 Methods:We identified 95 patients with colorectal epithelial neoplasms at our institution. The radiographic and colonoscopic findings were retrospectively investigated.

 Results:The frequencies of smooth surfaces, irregularities in depression, and eccentric deformities under BE were higher in massively submucosal invasive(mSM)carcinomas as compared to those in adenomas, intramucosal carcinomas, and slightly submucosal invasive carcinomas. The accuracies of BE, CE, M-NBI, and MC findings for the diagnosis of mSM carcinomas were 78.9%, 78.9%, 89.5%, and 85.3%, respectively. The above-mentioned BE findings had the highest sensitivity, although their specificity was low.

 Conclusions:We consider the combination of endoscopic and radiographic procedures to be invaluable for the determination of invasion depth of colorectal epithelial neoplasms.
