Abdominal X-ray and overall colonoscopy after stent implantation. Plain abdominal X-ray performed on the day of stenting showed that the stent was partially expanded (arrow, A). On post-placement day 1, the stent showed further expansion (arrow, B), and on day 2 showed full expansion (arrow, C). Colonography showed that the stenotic sigmoid colon segment was successfully expanded (arrow, D). On day 6, plain abdominal X-ray showed that the stent remained completely expanded and stably positioned (arrow, E). On day 8, electronic colonoscopy showed the stenotic sigmoid colon segment was expanded by the metallic stent, with local colonic mucosa embedded in the stent meshes, and the colonic mucosa in the upper part of the stent showed congestion, edema, erosion and ulcer (arrow, F). The endoscope was able to pass through the stenotic segment, and the colonic mucosa in the upper edge of the stent showed congestion and edema (arrow, G). The mucosa of the terminal ileum (H), ileocecal junction (I), transverse colon (J), descending colon (K) and rectum (L) was smooth, had clear vascular texture, and showed no erosion, ulceration or neoplasm.
