The effect of biliary stents implanted before pancreaticoduodenectomy in periampullary tumors on postoperative results: a retrospective analysis of 106 consecutive cases at a single medical center.

An advanced age and the presence of stents were independent risk factors influencing morbidity development according to the multivariate analysis.
