About this study
Official title: Underwater Endoscopic Mucosal Resection a Learning Curve Study
The global aim of this multi-centric study is to assess the learning curve of U-EMR by an endoscopist skilled in C-EMR aiming to assess the application in real world and check the rate of complete EMR and adverse events related to the procedure.
Read the detailed description
Conventional Endoscopic mucosal resection (C-EMR) is currently the standard therapy for the removal of large colon polyps. The procedure consists on the injection of fluids into the submucosa layer below the lesion with the intention to create a cushion to separate it from the muscular layer and avoid its damage and consequently perforation and thermal injury. There are some drawbacks about this technique such us fibrotic polyps, difficult location (areas behind the fold and appendicular orifice) and recurrence rate which without ablation techniques could reach 30%.
Underwater endoscopic mucosal resection (U-EMR) has been first described in 2012 by Binmoeller et al [10] and the main difference to C-EMR was the absence of need the submucosal injection. This would be possible because when the lumen is filled with water, the mucosal and the submucosal layer tend to float while the muscularis propria maintains its circular shape even in the presence of peristalsis. Recent data as shown not only a lower rate of recurrence but also a lower procedure time and R0 resections with no difference in adverse events.
Therefore, the global aim of this multi-centric study is to assess the learning curve of U-EMR by an endoscopist skilled in C-EMR aiming to assess the application in real world and check the rate of complete EMR and adverse events related to the procedure.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
learning curve of Underwater mucosectomyOther
Patients will be submitted to underwater mucosectomy (U-EMR)
| Study group | Role | What they receive |
|---|---|---|
| Underwater mucosectomy | Experimental | Every colonoscopy should be performed with a high definition colonoscope, such as Olympus series Q185 or Q190 with virtual chromoendoscopy by NBI (Olympus Inc., Tokyo, Japan) or Fujifilm EC-760R-V/L or EC-760Z-V/L with virtual chromoendoscopy by LBI (Fujifilm Group, Japan).
A study investigator or a senior endoscopy fellow under their direct supervision should perform all procedures.
The U-EMR procedure should include the following steps: CO2 should be completely removed, and the bowel lumen filled with normal saline using a water jet pump (OFP-2, Olympus Medical System or similar) until the lesion is totally immersed in water. The lesion and 2-3 mm of normal surrounding mucosa should be resected using electrocauterization (VIO 200D Endocut Q Effect 3; ERBE Electromedizin, Tübingen, Germany).

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2024; AzTrials last refreshed its copy on 27 Oct 2026.
