(A) Endoscopic view of small polypoid lesions with scar formation near the diverticulum. (B) Endoscopic view of the polyp after indigo carmine dye spraying. The colonic polyp exhibiting a type IIIL pit pattern extended into the diverticulum. (C) A band-ligator device was attached to the tip of endoscope. (D) Endoscopic view of the everted diverticulum after EBL. (E) The banded diverticulum resolved, and scar formation at the site was observed on follow-up colonoscopy. (F) Residual small polypoid lesions were resected using EMR, and additional electrocautery was performed at the site.

Colonoscopy revealed small polypoid lesions near a diverticulum in the ascending colon (Figure 1A). Indigo carmine dye spray during colonoscopy revealed a type IIIL (large or long) pit pattern on the polyp surface, and the lesion was classified as a tubular adenoma (Figure 1B). Tokyo, Japan) to the tip of the endoscope (Figure 1C). The diverticulum was everted after EBL (Figure 1D). The banded diverticulum resolved, and scar formation was observed on follow-up colonoscopy performed 2 months after EBL (Figure 1E). Residual small polypoid lesions were resected using EMR, and additional electrocautery was performed at the site (Figure 1F), without perforation or bleeding complications.
