A 59-year-old woman, who underwent uterectomy for uterine cancer in February 2000, was diagnosed having carcinomatous peritonitis with intractable ascites due to recurrent uterine cancer in November 2004. We conducted a peritoneovenous shunting at the right side of the abdominal cavity using the Denver peritoneovenous shunt system. A significant reduction in body weight and abdominal girth was seen during the follow up period. After 2 months, the intractable ascites was aggrayating. Because of the partition of the abdominal cavity by the greater omentum, the intractable ascites was dominant in the left side of the abdominal cavity compared with the right side. So we tried additional moreperitoneovenous shunting at the left side of the abdominal cavity using the Denver peritoneovenous shunt system. Finally, ascites and body weight were decreased. She was discharged from our hospital with a good quality of life. Double peritoneovenous shunt (Denver peritoneovenous shunt system) is a useful palliative treatment for intractable such as this case. Further experience and discussion are necessary to indicate this procedure.
