A 89-year-old woman was admitted to our hospital with vomiting and appetite loss. Abdominal CT revealed thickening of the sigmoid colon with an abscess cavity and ileus. A colonoscopy was performed, which revealed subtotal malignant obstruction of the sigmoid colon. A diagnosis of abdominal abscess resulting from penetration of sigmoid colon cancer was made. The patient was administered conservative therapy alone, as she was an unsuitable candidate for surgery. The size of the abscess cavity decreased and symptomatic remission was achieved. A colonic stent insertion was carried out to relieve the intestinal obstruction. Three days after insertion of the stent, a passage between the abscess cavity and sigmoid colon was identified on abdominal CT. This fistula was completely sealed by an esophageal covered stent. These procedures enabled the patient to take food orally. However, the patient died suddenly on day 34 after the stenting. In the present case, an esophageal covered stent was effective to seal the fistula resulting from a colonic stent insertion.
