Magnifying Endoscopic Findings Can Predict Clinical Outcome during Long-Term Follow-Up of More Than 12 Months in Patients with Ulcerative Colitis

Table 1

Summary of relationship between ulcerative colitis treatment, Matts endoscopic grade, magnifying endoscopic (ME) classifications following crystal violet staining, and microvascular pattern (MVP).

Therapy	Matts grade		ME classification				MVP type
	Matts 1	Matts 2	ME-A; (𝑛=5)	ME-B; (𝑛=24)	ME-C; (𝑛=10)	ME-D; (𝑛=7)	MVP-R; (𝑛=21)	MVP-IR; (𝑛=25)
Mesalazine (𝑛=29)	7	22	2	15	9	3	11	18
Salazosulfapyridine (𝑛=5)	4	1	2	3	0	0	4	1
Azathioprine (𝑛=1)	1	0	0	1	0	0	1	0
Azathioprine + mesalazine (𝑛=5)	1	4	0	2	0	3	1	4
None (𝑛=6)	2	4	1	3	1	1	4	2

ME-A: regular arrangement of normal-appearing round to oval pits; ME-B: irregular arrangement with/without enlarged spaces between the even pits; ME-C: irregular pits in size and shape with more irregular arrangement of pits compared to ME-B; and ME-D: disrupted or disappeared pits. MVP-regular: regularly arranged in a honeycomb-like structure; MVP-irregular: MVP with irregular, tortuous structure.
