What can be the criteria of outpatient-based endoscopic resection for colon polyp?

Table 3 Multivariate analysis to define independent risk factors for delayed bleeding

	OR	95%CI	P value
Size	1.1291	1.096-1.164	< 0.001
Pedunculated type	1.497	0.634-3.534	0.357
Immediate serious bleeding	9.150	0.591-3.506	0.413
Piecemeal resection	2.265	0.815-6.292	0.117
Chronic renal failure	9.150	1.856-45.106	0.007
Immediate post-EMR bleeding2	1.447	0.597-3.506	0.413

¹The risk of delayed bleeding after endoscopic mucosal resection increases 12.9% as the size of the polyp increases 1 mm;

²Serious immediate bleeding was defined as bleeding which required hemostatic clip application.
