METHODS:From 3/1996 to 6/2001,172 consecutive patients, who underwent placement of a single 10F-polyethylene stent for inoperable malignant strictures of the common bile duct,were randomly assigned to 2 groups.In group A(96 patients),a ES was performed before PS placement In Group B,96 patients had PS directly.Early complications(within 30 d)and late effects(from 30 d to stent replacement)were assessed.Patency interval was defined as the period between PS placement and obstruction or death.The success of stent replacement in the 2 groups was evaluated. RESULTS:Stent insertion was successful in 95.8%(92/96) of the pts in group A and in 93.7%(90/96)of the patients in group B(P>0.05).Early complications were more frequent in patients who underwent ES(6.5% vs4.4%)but the data were not significant(P>0.05).In group A pancreatitis developed in two patients and bleeding in three;whereas pancreatitis occurred in 2 patients in group B.Complications were managed conservatively.No procedure related mortality occurred.All late complications were acute cholangitis due to stent occlusion.We performed a stent replacement in 87 patients that was successful in 84 cases without differences between groups. CONCLUSION:Sphincterotomy does not seem to be necessary for placement of 10F-PS in patients with malignant common bile duct obstruction.展开更多
