TABLE 4:

Stricture Classification Based on Grade of Inflammation and Fibrosis on Bowel Ultrasound

	SWE value ＜22.55 Kpa	SWE value ≥22.55 Kpa
Limberga I/II	Low inflammation Low fibrosis (n = 2)	Low inflammation Marked fibrosis (n = 7)
Limbergb III/IV	Low fibrosis Severe inflammation (n = 16)	Severe inflammation Marked fibrosis (n = 10)

_aLimberg score of bowel vascularization was graded as I, II, III ,and IV by color Doppler ultrasound: grade I, intestine wall thickening (＞3 mm) without discovered vascularization; grade II, intestine wall thickening with spot vascular signals; grade III, intestine wall thickening with longer vascular signals; and grade IV, intestinal wall thickening with longer vascular signals extending from the mesentery.
