[Ileal invaginations caused by Peutz-Jeghers polyposis].

The Peutz-Jeghers syndrome is considered a familial polyposis syndrome. The polyps are of hamartomatous type. The symptomatology is due to the more voluminous polyps which can necrotize, ulcerate, bleed and cause intussusception and intestinal obstruction. A case of ileum-ileal intussusception due to Peutz-Jeghers syndrome is reported. The utility of a genealogic research is underlined and the recent results of the genetic research are evaluated. The surgical therapy of Peutz-Jeghers syndrome can have many aims: 1) to remove all big polyps, 2) to avoid the danger of canceration, 3) to prevent the hemorrhagic or occlusive risks and complications.
