title: [Mathematical-physical deliberations over the development of artificial-anus prolapse (and the therefrom derived attachment technic for the artificial anus)].
abstract: It is established that most colostomies which lead to prolapse because of imperfect operative technique are shaped like a truncated cone. Mathematical-physical considerations show mechanisms which in such cases can produce prolapse of the colostomy. Considering these criteria and recent clinical experience, a suitable colostomy is described.
