conclusions (1)
largest series
1st in a population-based setting
in the real world 1 / 5 patients with a benign large polyp is operated on 2 / 5 with a benign giant polyp
![Page 20: Treatment of large and giant colorectal polyps in the real world Stéphanie HUSSON, Guy VENTRE, Frédéric VAGNE, Jean François VIES, Marjorie MUSSO, Jean](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c815503460f94939d7c/html5/thumbnails/20.jpg)
B. Denis - DDW 2007 – Washington DC
conclusions (2)
referral to surgery related to sessile or flat shape size, proximal or rectal location, malignancy and lack of referral to an expert endoscopist
EMR performed by a minority (41.2%)
referral to an expert is rare (4.6%)
![Page 21: Treatment of large and giant colorectal polyps in the real world Stéphanie HUSSON, Guy VENTRE, Frédéric VAGNE, Jean François VIES, Marjorie MUSSO, Jean](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c815503460f94939d7c/html5/thumbnails/21.jpg)
B. Denis - DDW 2007 – Washington DC
future
need for
teaching (spreading) endoscopic techniques
for the management of large polyps
promoting referral of difficult large polyps to expert endoscopists to avoid unnecessary surgery
