Suitable lesions for endoscopic treatment include not only early colorectal carcinomas but also several types of precarcinomatous adenomas. It is important to establish practical guidelines wherein preoperative diagnosis of colorectal neoplasia and selection of endoscopic treatment procedures are appropriately outlined and to ensure that actual endoscopic treatment is useful and safe in general hospitals when carried out in accordance with guidelines. In cooperation with the Japanese Society for Cancer of the Colon and Rectum, the Japanese Society of Coloproctology, and the Japanese Society of Gastroenterology, the Japan Gastroenterological Endoscopy Society compiled colorectal endoscopic submucosal dissection/endoscopic mucosal resection guidelines by using evidence‐based methods in 2014. The first edition of these guidelines was published 5 years ago. Accordingly, we have published the second edition of these guidelines based on recent new knowledge and evidence.

Superficial neoplastic lesions of the digestive tract are usually asymptomatic, and often represent incidental findings on endoscopy. The Paris Classification was developed for the systematic evaluation of superficial lesions of the oesophagus, stomach and colon. The significance of this classification in clinical practice is that it allows the depth of invasion to be estimated. Chromoendoscopy is used to improve the visualization of gastrointestinal lesions. There are 2 types of chromoendoscopy: dye and virtual chromoendoscopy. In addition to chromoendoscopy, advanced endoscopy techniques have great importance in the detection of early gastrointestinal lesions. Although the depth of invasion can be estimated by endoscopy, the final decision regarding therapeutic approach is made on the basis of histopathological examination, as obtained by biopsy or endoscopic resection (ER). Polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection may be considered ER. For early gastrointestinal lesions with or without limited submucosal infiltration, ER can serve as therapy. In patients with neoplastic lesions localized deeper than the submucosa, or if the location of the lesion carries a high risk of perforation, a full-thickness resection can be performed. Guidelines for assessment and therapy of early oesophageal, gastric and colorectal lesions are currently available.

Cold versus hot polypectomy/endoscopic mucosal resection–A review of current evidence

et al. 2021

View full text Add to dashboard Cite

Background: Colonoscopy with polypectomy substantially reduces the risk of colorectal cancer (CRC) but interval cancers still account for 9% of all CRCs, some of which are due to incomplete resection. Aim:The aim of this review is to compare the outcomes of cold and hot endoscopic resection and provide technical tips and tricks for optimizing cold snare polypectomy.Results: Cold snare polypectomy (CSP) is the standard technique for small (≤10 mm) colorectal polyps. For large colonic polyps (>10 mm), hot resection techniques with use of electrocautery (polypectomy or endoscopic mucosal resection) were recommended until recently. However, the use of electrocoagulation brings serious adverse effects in up to 9% of the patients, such as delayed bleeding, post-polypectomy syndrome and perforation. In recent years, efforts have been made to improve the polypectomy with cold snare in order to avoid these adverse effects of electrocoagulation without compromising the efficacy of the resection. Several authors have recently shown that the complication rates of CSP of polyps >10 mm is close to zero and recurrence rates varies between 5-18%. Lower recurrence rates are found in serrated lesions (<8%).
