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

Table 2

Summary of relationship between ulcerative colitis treatment, magnifying endoscopic (ME) classifications following crystal violet staining, and microvascular pattern (MVP) in cases of Matts-2 endoscopic grade.

Therapy	ME classification				MVP type
	ME-A; (𝑛=0)	ME-B; (𝑛=14)	ME-C; (𝑛=10)	ME-D; (𝑛=7)	MVP-R; (𝑛=7)	MVP-IR; (𝑛=24)
Mesalazine (𝑛=22)	0	10	9	3	5	17
Salazosulfapyridine (𝑛=1)	0	1	0	0	0	1
Azathioprine + mesalazine (𝑛=4)	0	1	0	3	0	4
None (𝑛=4)	0	2	1	1	2	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.
