“…For pit pattern analyses, indigo carmine (0.4%) was sprayed directly on the mucosal surface after washing with proteinase to remove any overlying mucous. The mucosal crypt patterns observed with chromoendoscopy were assessed using Kudo's classification 16–18 . In the case of NBI, four different microvascular architecture patterns were identified according to Sano's classification 1,5,6,19 …”

Both NBI and chromoendoscopy can be useful for distinguishing between neoplastic and non-neoplastic lesions. In the diagnosis of submucosal cancer, pit pattern diagnosis was slightly superior to vascular pattern diagnosis. It is desirable to perform chromoendoscopy in addition to NBI for distinguishing between slightly and massively invasive submucosal cancer lesions and determining the treatment.

“…Colorectal adenomas and early carcinomas can be grossly divided into three groups; protruded or polypoid, flatelevated, and depressed. 7 The depressed-type colorectal cancers can be absolutely depressed or can be accompanied by a slightly elevated margin. Some flat-elevated adenomas spread extensively and circumferentially along the colonic wall although they are very short in height.…”

In colorectal cancers, although flat and depressed-type lesions are found by regular endoscopic view, magnification and pit-pattern observation are vital parts of the precise diagnosis of the lesion. The depressed-type lesions appear to have a prominent tendency to show malignant characteristics, and the recognition and timely treatment of such lesions is important for improving the morbidity and mortality of colorectal cancer. Chromoscopy is mandatory for an accurate diagnosis of these lesions. The pit-pattern classification correlates well with actual histological findings and can provide important additional information prior to endoscopic treatment of the lesion.
