Colonoscopy findings at week 12 of tacrolimus administration. The scope was inserted up to the end of the ileum. Erosion was present at the end of the ileum (c). Bauhin's valve (a, b) was slightly dilated, and the round ulcer expanded compared with that on the previous colonoscopies. In the ileocecum over the ascending colon, reddening was partially noted, but visible vascular patterns were improved. In the transverse colon (b) over the sigmoid colon, ulcer scars and inflammatory polyps were noted but shrunk compared with those on the previous colonoscopies. Healed mucosa was noted in the rectum.
