A study to evaluate the usefulness of traction-assisted endoscopic submucosal dissection using a newly developed all-in-one device used to resect colorectal polyps: a Multicenter Randomized Controlled Trial

Project description:Interventions: Procedure/Surgery : 1) onestep knife conventional ESD (control) ? Insert the colonoscope with the transparent cap attached. ? After puncturing the submucosal layer immediately around the lesion with a puncture needle for submucosal solution injection, inject the saline-based submucosal solution. ? When the lesion is sufficiently raised, submucosal dissection is performed using a dual knife. ? Retrieve the resected specimen, fix it on a styrofoam fixing plate, and ask the pathology department for tissue analysis. (2) onestep knife + Traction ESD (intermediate group) ? Insert the colonoscope with the transparent cap attached. ? After puncturing the submucosal layer immediately around the lesion with a puncture needle for submucosal solution injection, inject the saline-based submucosal solution. ? When the lesion is sufficiently raised, submucosal dissection is performed using a dual knife. ? When performing ESD, make an incision around the lesion. After fixing the rubber band to the endoscope clip from the outside of the patient, insert it into the channel of the colonoscope and fix the clip at the end of the pre-incision lesion using the clip. Using the second clip, hold the rubber band secured to the pre-fastened first clip and secure the clip in a position that will provide adequate traction. ? Implement additional ESD. ? Retrieve the resected specimen and fix it on a styrofoam fixing plate, and then ask the pathology department for tissue analysis Primary outcome(s): procedure time; resection speed Primary Purpose : Treatment, Intervention Model : Parallel, Blinding/Masking : Single, Blinding Target : Subject, Allocation : RCT

Efficacy and Safety of Multi Loop Traction Device-assisted Colorectal Endoscopic Submucosal Dissection: A Multicenter, Randomized Clinical Trial

Project description:Interventions: 1) MLTD-ESD group Colorectal endoscopic submucosal dissection (ESD) is performed using the Multi Loop Traction Device (MLTD). The number of MLTD used in a single session is not limited. The conversion of the allocated therapeutic method is permitted. If the MLTD is ineffective for more than 10 minutes, the MLTD can be removed. 2) Conventional ESD group ESD is completed using a standard therapeutic strategy that does not involve the use of traction devices. The conversion of the allocated therapeutic method is permitted. The MLTD can be used if the endoscopist determines that the traction device has been required for more than 10 minutes. Primary outcome(s): Dissection speed (area resected [mm^2]/duration in minutes) Study Design: Parallel Randomized

Traction-assisted colonic endoscopic submucosal dissection using clip and line: a feasibility study.

Project description:Colonic endoscopic submucosal dissection (ESD) is a challenging procedure because it is often difficult to maintain good visualization of the submucosal layer. To facilitate colonic ESD, we designed a novel traction method, namely traction-assisted colonic ESD using clip and line (TAC), and investigated its feasibility.We retrospectively analyzed 23 patients with large colonic superficial lesions who had undergone TAC. The main outcome was the procedural success rate of TAC, which we defined as successful, sustained application of clip and line to the lesion until the end of the procedure.The procedural success rate of TAC was 87 % (20/23). In all three unsuccessful cases, the lesions were in the proximal colon and the procedure times over 100 minutes. The overall mean procedure time was 61 min (95 % confidence interval, 18 - 172 min). We achieved en bloc resections of all lesions. There were no perforations or fatal adverse events.TAC is feasible and safe for colonic ESD and may improve the ease of performing this procedure.
