Abstract
Expandable metallic stent (EMS) is widely used technique for the management of eso-phageal cancer and bile duct obstruction. However, the reports on EMS placement for malignant rectal stenosis were rare. We performed EMS placement for malignant rectal stenosis caused by Schnitzler's metastasis. A 45-year-old woman, who had suffered from stage IVb stomach cancer, had been treated with chemotherapy. She visited to our hospital because of abdominal fullness, nausea and vomiting. Barium enema and colonoscopy revealed marked stenosis in the rectum. We diagnosed the lesion as malignant rectal stenosis caused by Schnitzler's metastasis, and EMS were performed. After EMS placement (UltraflexTM, Microvasive, Boston Scientific Corpora-tion, MA, USA), the patient recovered to control flatulence and defecation by herself perfectly. Neither bleeding nor tenesmus had occurred. Following up for three months, stent patency and relief of bowel obstruction were shown. In conclusion, EMS is technically safe, and useful therapy for rectal malignant stenosis.
