We reported the outcome of colorectal peritoneal dissemination resection. Eleven patients who underwent R0 resection for colorectal peritoneal dissemination from January 2009 to December 2017 were examined in our hospital. The median observation period was 23 months, the 3-year overall survival rate was 72.8%, and the 3-year relapse free survival rate was 22.7%. Thus, surgical resection might be useful for peritoneal dissemination.
