The COlorectal NEoplasia Endoscopic Classification to Choose the Treatment classification for identification of large laterally spreading lesions lacking submucosal carcinomas: A prospective study of 663 lesions.

Introduction: Optical diagnosis is necessary when selecting the resection modality for large superficial colorectal lesions. The COlorectal NEoplasia Endoscopic Classification to Choose the Treatment (CONECCT) encompasses overt (irregular pit or vascular pattern) and covert (macroscopic features) signs of carcinoma in an all-in-one classification using validated criteria. The CONECCT IIC subtype corresponds to adenomas with a high risk of superficial carcinoma that should be resected en bloc with free margins.

EUS-guided biliary drainage with electrocautery-enhanced lumen-apposing metal stent placement should replace PTBD after ERCP failure in patients with distal tumoral biliary obstruction: a large real-life study.

Aims: In cases of malignant distal biliary obstruction, ERCP is the preferred technique for bile duct drainage. In case of failure, the alternative techniques are percutaneous transhepatic biliary drainage (PTBD) and more recently endoscopic ultrasound-guided biliary drainage. A new type of stent called the electrocautery-enhanced lumen-apposing metal stent (EC-LAMS) has been developed to enable the performance of biliary-enteric anastomosis under EUS-guidance in a single step, without prior bile duct puncture or the need for a guidewire.

Video clips compared with high-definition still images for characterization of colorectal neoplastic lesions: a randomized comparative prospective study.

 Accurate real-time characterization of colorectal neoplastic lesions (CNLs) during colonoscopy is important for deciding appropriate treatment. No studies have evaluated whether still images or video clips are better for characterization. We compared histological predictions and size estimations of CNLs between two groups of gastroenterologists: one viewing still images and the other viewing video clips.

Double-clip traction for colonic endoscopic submucosal dissection: a multicenter study of 599 consecutive cases (with video).

Background And Aims: Colonic endoscopic submucosal dissection (ESD) is particularly challenging and limited to a few expert centers. We recently conducted a pilot study on improvement of colonic ESD with systematic use of a countertraction device (double-clip traction with rubber band [DCT-ESD]).

Methods: A French prospective multicenter study was conducted between March 2017 and September 2019, including all consecutive cases of naive colonic ESD.

Effect of implementing a regional referral network on surgical referral rate of benign polyps found during a colorectal cancer screening program: A population-based study.

Introduction: Surgical management is too often performed as the first-line treatment for large, benign colorectal polyps. We report the management of benign lesions detected by organised colorectal cancer (CRC) screening.

Methods: Population-based study in 2012, 2016, and 2017, analyzing the evolution of surgical management of benign polyps of≥2cm diameter discovered in the context of organised CRC screening after the implementation of a regional referral network for the management of superficial colorectal lesions.
