Endoscopic resection of colitis-associated neoplasia: A scoping review

Table 2 Studies evaluating endoscopic mucosal resection in ulcerative colitis

Ref.	Patients (n)	EMR type	Lesion type	Key outcomes	Comments
Hurlstone et al[11], 2007	712	Conventional EMR	Paris 0-II, ALM, LST	93% en bloc; 2.4% recurrence; no perforations	Validated safety and efficacy in UC
Moyer et al[12], 2024	16	Distal cap EMR	Non-lifting dysplasia	75% complete resection; 0 SAEs; thermal margin ablation used	Ideal for fibrotic/adherent lesions
Hosotani et al[2], 2022	1	UEMR	Flat adenoma with fibrosis	Complete R0 resection; no complications	First UEMR case in UC with fibrosis
Takabayashi et al[13], 2022	1	UEMR	Lesion over ulcer/tattoo	En bloc resection; negative margins; safe in fibrotic UC	Demonstrates feasibility in scarred mucosa

EMR: Endoscopic mucosal resection; ALM: Adenoma-like mass; LST: Lateral spreading tumor; SAEs: Serious adverse events; UEMR: Underwater endoscopic mucosal resection; UC: Ulcerative colitis.
