Endoscopic appearance of pancolitis pre- and post-FMT treatment after long-term follow-up in patients with recurrent active UC. The endoscopic appearance includes mucosal hyperemia and edema, mucous exudate erosions, multiple ulcers and spontaneous bleeding in the ileocecum (a), ascending colon (b), sigmoid colon (c) and rectum (d) before FMT therapy. Markedly improved lesions with normal mucosa were observed at 24 months after a single fresh FMT. A single fresh FMT can achieve long-term remission without drugs and no obvious adverse events in patients with recurrent active UC
