    Abstract:
    BACKGROUND: Symptomatic common bile duct strictures are frequently seen in the course of severe chronic pancreatitis with a reported incidence of 10-30%. The exact role of endoscopic stenting with metal prostheses as definitive treatment has not yet been clearly defined. METHODS: Six patients with symptomatic distal common bile duct stricture in the setting of chronic pancreatitis were treated with a self-expandable metal stent in an attempt to achieve permanent drainage. All cases were approached non-operatively and underwent prior unsuccessful treatment with plastic prostheses. RESULTS: The patients received a self-expandable metal Wall stent after a median follow-up of 14 months of plastic stenting. The median follow-up time was 58 months and the stents remained open for a median time of 20 months, respectively. Overall, in 2 of 6 cases the metal stent therapy was successful while 4 of 6 patients required additional endoscopic procedures. CONCLUSIONS: Self-expandable metal stents could be useful and adequate in patients who suffer from symptomatic obstructive jaundice due to chronic pancreatitis. However, they provide acceptable dilation of the common bile duct for only a limited period of time. Overall, endoscopic stenting with self-expandable metal stents seems to be an advantageous treatment only for a subgroup of patients who are unfavorable candidates for surgical drainage. To clarify the role of the endoscopic approach, prospective trials with homogeneous and larger patient numbers are necessarily in the future.
