A 51-year-old man presented to our hospital with complaints of blood in his stool and abdominal pain. Contrast-enhanced computed tomography scanning revealed thickening of the rectal wall and dilatation of the oral colon. The patient was diagnosed with obstructive rectal cancer. Retrograde bowel drainage was performed. Subsequently, he relapsed colonic obstruction and ileostomy was performed. Following lower anterior resection and adjuvant chemotherapy, stoma closure was scheduled. However, colonoscopy revealed colon stenosis caused by obstructive colitis from the transverse colon to the descending colon. Balloon dilatation was performed twice; however, adequate improvement was not noted in the colon stenosis. Local injection of a steroid was performed immediately following balloon dilatation. The colon stenosis improved after four balloon dilatations and two local steroid injections. Eventually, stoma closure was performed and his postoperative course was favorable.
