Ischemic or toxic injury: A challenging diagnosis and treatment of drug-induced stenosis of the sigmoid colon

Figure 7 Stent placement for sigmoid colon stenosis. The patient underwent stent placement for sigmoid colon stenosis. A guide wire was inserted via electronic colonoscopy to the proximal end of the stenotic segment (arrow, A). X-ray radiography confirmed that the guide wire had achieved the correct position and showed that the stenotic segment was 4 cm long (arrow, B). Additionally, X-ray showed that an 8-cm-long self-expandable memory metallic stent had been placed at the correct location (arrow, C). Colonoscopy confirmed that the distal end of the stent was at the correct location (D).
