Figure 1. (A) Endoscopic white light image showing adenoma, 2nd portion, 0-IIa, 6 mm; (B) endoscopic narrow band imaging; (C)
endoscopic image with indigo carmine spraying; (D) snaring with 10 mm snare; (E) mucosal defect after CSP with a procedure time of 1
min; (F) complete prophylactic clipping with three clips; (G) resected specimen shown as a white light image; (H) resected specimen
shown by narrow band imaging; and (I) histopathological image with hematoxylin and eosin stain. The histopathological diagnosis was
tubular adenoma, pHM0, pVM0.

observed in 2 of 49 lesions (4.1%), which could be treated by cold forceps polypectomy or UEMR.
