TL;DR: ESD performed by experienced endoscopists is an effective alternative treatment to surgery, providing high en bloc and curative resection rates for large superficial colorectal tumors.
Journal ArticleDOI

TL;DR: The Japan NBI Expert Team was constituted with the aim of establishing a universal NBI magnifying endoscopic classification for colorectal tumors (JNET classification) in 2011, and consensus was reached on this classification using the modified Delphi method in June 2014.
Journal ArticleDOI
Efficacy of the invasive/non-invasive pattern by magnifying chromoendoscopy to estimate the depth of invasion of early colorectal neoplasms.

TL;DR: The determination of invasive or non-invasive pattern by MCE is a highly effective in vivo method to predict the depth of invasion of colorectal neoplasms.
Journal ArticleDOI
Long-term Outcomes After Resection for Submucosal Invasive Colorectal Cancers

TL;DR: The risk for local recurrence was significantly higher in high-risk patients with submucosal rectal cancer than in patients with SUBMucosal colon cancer when treated with only endoscopic resection, and the addition of surgery is recommended for patients with deep vein thrombosis with pathologic features indicating a high risk of tumor progression.
Journal ArticleDOI
Systematic review and meta-analysis of endoscopic submucosal dissection versus transanal endoscopic microsurgery for large noninvasive rectal lesions
Alberto Arezzo,Roberto Passera,Yutaka Saito,Taku Sakamoto,Nozomu Kobayashi,Naoto Sakamoto,Naohisa Yoshida,Yuji Naito,Mitsuhiro Fujishiro,Keiko Niimi,Tomohiko R.

TL;DR: The ESD procedure appears to be a safe technique, but TEM achieves a higher R0 resection rate when performed in full-thickness fashion, significantly reducing the need for further abdominal treatment.
