Endoscopic resection of colitis-associated neoplasia: A scoping review

Table 1 Summary of key studies on polypectomy in ulcerative colitis

Ref.	Patients (n)	Lesion type	Polypectomy outcome	Cancer risk post-polypectomy	Recommendation
Rubin et al[5], 1999	48	Dysplastic polyps in UC	48% developed new polyps; no flat dysplasia or cancer in follow-up	2% (1 case within polyp)	Polypectomy with surveillance
Odze et al[6], 2004	34	Adenoma-like DALM	62.5% recurred; 1 case of adenocarcinoma	About 3%	Polypectomy if lesion well-circumscribed
Vieth et al[7], 2006	148	Sporadic adenomas	4.6% had distant neoplasia; 2.3% carcinoma	2.3%	Adequate if followed by endoscopic monitoring
Engelsgjerd et al[9], 1999	Case series	Adenoma-like DALMs	Similar profile to sporadic adenomas	Minimal	Supports conservative management
Kisiel et al[8], 2012	77	Polypoid dysplasia	13% developed cancer/flat dysplasia	13% over 5 years	Requires close follow-up
Schaus et al[10], 2007	23	Ileal pouch polyps	91.3% inflammatory; 8.7% dysplastic/malignant	8.7%	Polypectomy + symptom monitoring

DALM: Dysplasia-associated lesion or mass; UC: Ulcerative colitis.
