title: Successful Self-Expandable Metallic Stent Placement for a Case of Distal Rectal Stenosis due to Gastric Cancer Metastasis.
abstract: A 47-year-old woman was diagnosed as having advanced gastric cancer with malignant ascites. Despite chemotherapy, recurrent peritoneal dissemination was seen 1.5 years after operation. A computed tomography scan revealed rectal stenosis due to Schnitzler's metastasis. When the distance from the distal end of the obstruction to the anal verge is less than 5 cm, stent replacement has been said to be contraindicated due to the development of anal pain and foreign body sensation. Although the distance from the distal end of the obstruction to the anal verge was 4 cm in this case, a WallFlex(TM) colonic stent could be placed. She stayed home, and luminal patency remained until she died 270 days after stent insertion. This report demonstrates that rectal obstruction located less than 5 cm from the anal verge due to Schnitzler's metastasis could be treated by stenting without any symptomatic or technical complications.
