Stage A2 BPU under OCUS and gastroscopy. (A) Stage A2 ulcer. OCUS shows the ulcer was sunken less deeply than in Fig. 1A, with no hypoechoic area surrounding the bottom and periphery. The mucosal oedema at the edge of the ulcer gradually subsided. (B) The same ulcer as in (A) under gastroscopy. There was thick, yellow-and-white coloured fur at the bottom of the ulcer, and the congestion and oedema of the surrounding mucosa were relieved.
