Figure 1 Flow chart of the research design and analysis. This figure was created with BioRender.com. A: Endoscopic excision of large nonpedunculated colorectal lesions might lead to significant adverse complications, such as delayed bleeding (DB) and delayed perforation (DP); B: Coverage of the wound after endoscopic excision supplies shield protection to reduce or prevent delayed complications, such as DB and DP. Large nonpedunculated colorectal lesions (≥ 20 mm).
