Flexible endoscopy techniques allow today different alternatives consisting of endoscopic mucosal resection or endoscopic submucosal dissection. The first is a straightforward and relatively easy technique, but it prevents a correct pathological staging of the lesion due to fragmentation and the verification of disease-free margins. The second relies on operators' audacity depending on their increasing experience due to the limited progress in technology. What is the preferable technique today is questionable. All the methods have pros and cons. The future certainly will see the use of ideal systems, allowing the possibility of precision surgery for partial- or full-thickness excision, depending on intraoperative findings, and the extension above the rectosigmoid junction. Miniaturized flexible robotic devices may represent the solution for both issues.<\/jats:p>","DOI":"10.1055\/s-0042-1744356","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T23:36:57Z","timestamp":1646091417000},"page":"106-112","source":"Crossref","is-referenced-by-count":4,"title":["Transanal Local Excision or Endoscopic Dissection for Benign and Large Lesions of the Rectum"],"prefix":"10.1055","volume":"35","author":[{"given":"Mario","family":"Morino","sequence":"additional","affiliation":[{"name":"Department of Surgical Sciences, University of Torino, Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Arezzo","sequence":"additional","affiliation":[{"name":"Department of Surgical Sciences, University of Torino, Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"issue":"02","key":"ref1","first-page":"73","article-title":"Transanal endoscopic surgery of the rectum - testing a new method in animal experiments [in German]","volume":"13","author":"G Buess","year":"1983","journal-title":"Leber Magen Darm"},{"issue":"10","key":"ref2","first-page":"677","article-title":"A system for a transanal endoscopic rectum operation [in German]","volume":"55","author":"G Buess","year":"1984","journal-title":"Chirurg"},{"issue":"05","key":"ref3","first-page":"247","article-title":"TEM results of the Tuebingen group","volume":"2","author":"B Mentges","year":"1994","journal-title":"Endosc Surg Allied Technol"},{"issue":"02","key":"ref4","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1007\/BF01648411","article-title":"Early (microinvasive) colorectal carcinoma.
