Quality of ulcer healing in gastrointestinal tract: Its pathophysiology and clinical relevance

Table 2 Morphological characteristics of active ulcers in patients with Crohn’s disease reflecting possible future mucosal healing after treatment with infliximab

Morphological finding		Mucosal healing
		Good (n = 10)	Poor (n = 11)	P value1
Shape of ulcer edge	Flat	8	3
	Non-flat	2	8	0.03
Fold convergence	Negative	7	3
	Positive	3	8	0.08
Shape of ulcer base	Flat	4	3
	Non-flat	6	8	0.65
Stenosis	Negative	8	9
	Positive	2	2	0.99
Neighboring ulcer	Negative	9	4
	Positive	1	7	0.02
Width of ulcer	Narrow	9	4
