  • the known system comprises a conduit which diverts bile and pancreatic secretions from the ampulla of Vater to a location d own strea m i n th e gastrointestinal tract.
  • the known conduit catheters extend inside the intestine and tend to bundle up and to be displaced by the peristalsis of the intestinal tract so that the distal end of the catheter is frequently relocated far away from the target position intended by the surgeon.

Abstract

La présente invention concerne un procédé pour dériver un fluide biliaire depuis un chemin d'écoulement de fluide biliaire vers un emplacement cible dans l'intestin distal par rapport à une papille duodénale de Vater, le procédé comprenant les étapes de visualisation d'une vésicule biliaire (8) et d'une partie du tractus intestinal (2, 3, 4, 5), d'accès endoluminal à la partie du tractus intestinal (2, 3, 4, 5), d'extension d'un guide (11) depuis la partie du tractus intestinal à travers une paroi de vésicule biliaire et à travers une paroi intestinale au niveau d'une partie cible (12) de l'intestin significativement distale par rapport à la papille de Vater (10), de rapprochement de la vésicule biliaire (8) et de la partie cible (12) de l'intestin l'une vers l'autre le long du guide (11) et d'anastomose de la vésicule biliaire (8) avec la partie cible (12) de l'intestin pour créer une cholécysto-entérostomie (13).
