A Case of Colostomy Stricture Caused by Peritoneal Metastasis of Rectal Cancer with Self-Expandable Metallic Stent Therapy

Abstract

We report the use of a self-expandable metallic stent (SEMS) for a colostomy stricture caused by peritoneal metastasis of rectal cancer. An 87-year-old woman underwent laparoscopic low anterior resection for rectal cancer in 2012, and Hartmann's procedure for local recurrence in 2014. The first histological findings of the tumor showed moderately differentiated adenocarcinoma (T3, N1b, ly1, v1, P0, H0, M(-), pStageIIIA (TMN)). She complained of abdominal pain, constipation, and abdominal distension in 2015. A colostomy stricture due to peritoneal metastasis of rectal cancer was diagnosed. We performed SEMS insertion therapy from the colostomy. Immediately following insertion, a lot of stool was passed via the stent. SEMS therapy was a useful palliative option and was minimally invasive.
