Abdominal computed tomography (CT) demonstrated short segment of circumferential luminal narrowing at sigmoid colon, measured about 4.4 cm in length and 2.3 cm in wall-to-wall diameter, with a few of subcentimeter pericolic nodes (Fig. 1A). Furthermore, there was the presence of pneumatosis coli at cecum and ascending colon (Fig. 1B).
Endoscopic finding. A: A guide-wire was passed through the lesion; B: Fluid content was flowed out after fully deployment of the stent.

At colonoscopy, we found 50% circumferential ulceroproliferative mass at 40 cm from anal verge, about 4 cm in total length, with nearly complete obstruction (Fig. 2A). MA, USA) 25 mm x 90 mm was successfully placed to cover the point of obstruction (Fig. 3A and B). Massive liquid stool was drained out (Fig. 2B).
Abdominal x-ray. A: and B: After SEMS placement, plain abdominal film showed dumbbell-shaped metallic stent after deployment with no abnormal dilatation of the bowel (red arrow).
