First colonoscopy at our hospital. a. Conventional (white light) image revealed an altered shape of the lesion. The lesion appeared smaller and more indistinct compared with that seen during the previous colonoscopy and it resembles a scar. b. Chromoendoscopic view with indigo carmine (0.4%) shows fold convergence but no apparent lesion. c. Narrow-band imaging with magnification revealed a faintly visible honeycomb pattern around the normal gland. This pattern was judged as Sano’s type I capillary pattern. d. Magnifying chromoendoscopy with crystal violet (0.05%) revealed a Kudo’s type IIIL or elongated type I pit pattern.
