@entity788 is the fourth leading cause of @entity5 related @entity204 in Western Countries. The 5-year survival for resectable @entity5 is 15-25%, while @entity1 with unresectable @entity5 survive a median of 7 months. Only 30% of @entity189 of the head of pancreas and 10% of the body and tail are resectable for cure. Therefore, palliation of symptoms, @entity3883 , @entity158 , involve 80-90% of cases. @entity1087 is frequent in @entity5 of the head. Palliative biliary decompression can be achieved by non surgical methods-endoscopically placed endoprostheses or percutaneous biliary drainage- or surgically. The former are indicated in @entity1 with @entity3 , high operative risk and short life expectancy. @entity954 which includes choledocho-duodenostomy, cholecystoduodenostomy, cholecystojejunostomy, hepato or choledocho-jejunostomy offers the advantage of providing a simple procedure that can treat or prevent all of the major symptoms: @entity1087 , @entity158 . Mechanical obstruction of the duodenum occurs in about 30% of cases in association with @entity1087 at the time of presentation and in 13-21% of @entity1 previously subjected to biliary bypass after 8 months. @entity3885 can be relieved by gastro-jejunostomy. Significant controversy remains concerning the role of prophylactic gastro-jejunostomy in @entity1 requiring biliary diversion without signs of @entity9727 . @entity158 , which sooner or later affects the majority of @entity1 , can be relieved by splanchnicectomy, either surgically or percutaneously.
