A man in Japan claims a hospital misdiagnosed his cancer and unnecessarily gave him an artificial rectum.

The man underwent surgery in March at a hospital in western Miyazaki to remove the tumor, the Mainichi Daily reported.

But his doctor told the man, whose age and name were not reported, that a later examination found no cancer cells in the removed tissue, the report said.

The man, who now has an artificial rectum, is demanding $416,171 in compensation, the report said citing the complaint filed with the Miyazaki District Court.

"We realize the complaint has been filed,'' a hospital official said.

"We will take appropriate action after examining the case.''
