A CASE OF EXPANDABLE METALLIC STENT PLACEMENT FOR THE STENOSIS IN THE SIGMOID COLON AND RECTUM DUE TO SCHNITZLER'S METASTASIS FROM GASTRIC CANCER

Abstract

A 54-year-old woman had undergone total gastrectomy and partial resection of transverse colon for stage IV gastric cancer (signet-ring cell carcinoma) at the age of 50. She admitted to our hospital because of anal bleeding and abdominal fullness. Barium enema and colonoscopy were done to confirm the diagnosis for Schnitzler's metastasis. It revealed the stenosis, approximately 17cm in length from the sigmoid colon to rectum. The histopathology of biopsy specimen from the rectum demonstrated signet-ring cell carcinoma. Thus, we diagnosed the cob-rectal stenosis caused by Schnitzler's metastasis. After placement of expandable metallic stent (EMS) at the stenotic lesion, the patient was able to maintain bowel activity for 5 months. It is suggested that EMS placement is a useful therapy in patients with malignant cob-rectal stenosis caused by Schnitzler's metastasis.
