A 69-year-old woman presented with constipation after being administered a sodium picosulfate and polyethylene glycol preparation prior to performing a follow-up colonoscopic examination. Abdominal radiography revealed dilated colon with laxative and niveau. Following administration of a glycerin enema, she returned home for defecation. At home, she passed a large amount of stool accompanied by hematochezia and abdominal pain the next morning. Colonoscopic examination revealed an edematous and erythematous mucosa, with longitudinal ulcers observed at the splenic flexure, as well as the descending and the sigmoid colon. Histopathological findings revealed purulent exudate, necrotic debris, and granulation tissue, compatible with ischemic colitis with an open ulcer. Her symptoms improved with conservative therapy. It is rarely reported a case of ischemic colitis occurring secondary to bowel preparation for colonoscopic examination.
