Straight plastic stents in tumors at the hepatic hilum and related duodenal perforations.

We read with interest the paper on the endoscopic treatment of a duodenal perforation related to a plastic biliary stent that was reported by Roa et al. We would like to add some comments about biliary stents inserted during endoscopic retrograde cholangiopancreatography (ERCP) to palliate malignant jaundice in hilar strictures. It is our belief that the most convenient strategy in non-operable patients should be the insertion of at least one uncovered self-expanding metal stent.
