Endoscopic Tactile Capsule for Non-Polypoid Colorectal Tumour Detection

[Narrow band imaging for detection of non-polypoid colorectal neoplasms].

Non-polypoid (flat and depressed) colorectal neoplasms (NP-CRNs) are more difficult to detect by conventional white light colonoscopy (WLC) or computed tomography colonography, because the subtle findings can be difficult to distinguish from those of normal mucosa. Narrow band imaging (NBI) has been reported to highlight the mucosal capillaries of neoplastic lesions, and thus increase the detec...

Tumour-associated and non-tumour-associated microbiota in colorectal cancer

OBJECTIVE A signature that unifies the colorectal cancer (CRC) microbiota across multiple studies has not been identified. In addition to methodological variance, heterogeneity may be caused by both microbial and host response differences, which was addressed in this study. DESIGN We prospectively studied the colonic microbiota and the expression of specific host response genes using faecal a...

Preinvasive colorectal lesion transcriptomes correlate with endoscopic morphology (polypoid vs. nonpolypoid)

Improved colonoscopy is revealing precancerous lesions that were frequently missed in the past, and ∼30% of those detected today have nonpolypoid morphologies ranging from slightly raised to depressed. To characterize these lesions molecularly, we assessed transcription of 23,768 genes in 42 precancerous lesions (25 slightly elevated nonpolypoid and 17 pedunculated polypoid), each with correspo...
