At Oslo University Hospital in Norway, maximal cytoreductive surgery (CRS) has been performed since 1994 for pseudomyxoma peritonei. For cases of peritoneal carcinomatosis from colorectal cancer, CRS has been performed since 2005.

For relevant patients, x rays and anamnesis is discussed and evaluated in a weekly specialist meeting involving radiologists, oncologists and surgeons.
