“In the Guideline, “Modifications in endoscopic practice for the elderly,” which was published in the July issue of Gastrointestinal Endoscopy (Gastrointest Endosc 2013;78:1-7), the author list was presented incorrectly. The correct list appears below. Prepared by: ASGE STANDARDS OF PRACTICE COMMITTEE “

Role of endoscopy in the staging and management of colorectal cancer. Gastrointest Endosc 2013;78:8-12), the second Recommendation on page 11 is incorrect. It should state “We recommend EUS in the preoperative locoregional staging of rectal cancer to guide therapy.” The online version of this article has been replaced with the correct version.

“In the article, “Serrated lesions and hyperplastic this website (serrated) polyposis relationship with colorectal cancer: classification and surveillance recommendations,” by Orlowska (Gastrointest Endosc 2013;77:858-71), Figure 2 was presented incorrectly, Figure 3 contained an error, and Table 2 was incorrectly aligned. The corrected Figures and Table appear below. Figure 2.  Serrated lesions histological classification. A, Hyperplastic polyp comprising glands with serrations limited mostly to the upper one half of the crypts. Nonbranching narrow crypts at the bases are similar in diameter and shape to those of normal colon (Fig. 1A). B, C, Sessile serrated lesions. Serrated architecture at all

levels of the crypts with broadened and irregular shape of their bottom parts. The basal portions of the crypts are branched, horizontal, and appear flask or T shaped (C); they are lined with a mixture of mature and dystrophic goblet cells. D, Sessile serrated lesion with focal dysplasia composed of nondysplastic sessile serrated component in the central part and dysplastic epithelial component at the right and left margins of the lesion. E, F, Traditional serrated adenoma. Serrated architecture with dysplastic hypereosinophilic Teicoplanin cytoplasm and confluent nuclear stratification is visible. Premature tiny crypts (F) perpendicular to the longitudinal axis of the villi, called an ectopic crypt formation, are distinctive. G, H, Two examples of serrated lesions with focal dysplasia (mixed polyps). G, Nondysplastic hyperplastic upper left part and dysplastic component with morphology resembling traditional serrated adenoma on the right-hand side of the lesion. H, There are two dysplastic elements characteristic of traditional serrated adenoma on the lower right and conventional adenoma on the upper left. “
“In the article from the ASGE Standards of Practice Committee, “Endoscopic mucosal tissue sampling” (Gastrointest Endosc 2013;78:216-24), the references included in the notes of Table 2 are inaccurate and should be ignored.
