Table 1. The list of the 10 quality indicators that should be monitored and reported in an ESD study.

Quality indicators for ESD procedure

1. Indications for ESD

2. Use of morphological criteria for the evaluation of the lesions (e.g., Paris, JNET, NICE classification) and supposed diagnosis (e.g., adenoma vs. cancer and deep of invasion) before ESD

3. En bloc/R0/oncologically curative (G1/2; L0/V0) resection rates

4. Histology (adenoma low- and high-grade dysplasia vs. cancer, sm1 vs. sm2 or deeper)

5. Technique used: standard and hybrid

6. Complications (need for surgery, perforation, bleeding, length of hospital stay)

7. Volume of ESDs performed per year (total and stratified according to the site, colon, stomach, esophagus)

8. Lesion location (e.g., rectum vs. colon)

9. Need for surgery after technically successful ESD

10. Time taken to perform the procedure

ESD, endoscopic submucosal dissection; JNET, Japan NBI Expert Team; NICE, NBI International Colorectal Endoscopic.
