LST-NG, especially pseudo-depressed type, the lesion that has a type of Vi pit pattern, shallow submucosal invasion, a large elevated lesion suspected cancer,
2)an intramural tumor with fibrosis of submucosal layer
3)a tumor caused by chronic inflammation such as ulcerative colitis
4)a residual tumor after endoscopic resection

Complete closure of the defect (median defect size 29.0 mm) was successfully achieved in 24 cases (80%). Delayed bleeding occurred in one case with incomplete closure (3.3%). The median ELOC procedure time was 25.5 minutes (interquartile range, 20.0 to 30.0 minutes). The sustained closure rates were 83.3% (20/24) on POD 3 in the 24 cases with complete closure.
