NCT06073561

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • learning curve of the application of U-EMR by endoscopists skilled in C-EMR

    evaluate the learning curve of the application of U-EMR by endoscopists skilled in C-EMR after an online course about U-EMR technique.

    6 months

Study Arms (1)

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).

Other: learning curve of Underwater mucosectomy
