[Peroperative estimation of the imperviousness of choledochoduodenal anastomoses]

Fistulae occurring after choledochoduodenostomy always have severe consequences. The following procedure aimed at checking for leakage is suggested by the authors. After completion of the posterior stage of the operation, a naso-gastric tube is introduced into the common bile duct, exposing the anterior suture; once the anastomosis has been performed, a fluid is injected into the tube by the anaesthetist, thus revealing any leakage. Once the incisions are covered, the naso-gastric tube is simply withdrawn on a few centimetres.
