Abstract:
Three cases of duodenal perforation which occurred after the placement of a biliary endoprosthesis, are reported. One intraperitoneal perforation required an immediate surgical intervention. The two other cases have been treated endoscopically and by transhepatic drainage, respectively. The mechanism of this delayed complication is discussed and the impact caused by the shape of the Carey-Coons endoprosthesis (Porges-Roche) analysed.
