A case of recurrent breast cancer with duodenal obstruction due to peritoneal dissemination

Abstract

We report a case of invasive breast cancer with duodenal obstruction due to peritoneal dissemination. A 55-year-old woman with right breast cancer was seen previously at another hospital and underwent right mastectomy in 2006. The other relapse sites could not be detected. She underwent examination for vomiting. As the patient showed no symptomatic improvement in response to conservative treatment, a laparotomy was performed. Peritoneal dissemination to the greater omentum and duodenal obstruction due to peritoneal dissemination were diagnosed.
We performed gastro-jejunostomy, by the modified Devine method. She has remained alive without bowel obstruction for 6 months to date while being treated with cytotoxic chemotherapeutic agents.
