Gallbladder stent placement for prevention of XXXX in @entity1 receiving covered metal stent for @entity3883 : a feasibility study.

@entity1 @entity3883 @entity1085 @entity5 @entity2679
PURPOSE: Covered self-expanding metal stents (CSEMS) have been used for palliation of @entity5 . Occlusion of the cystic duct by CSEMS may be complicated by @entity2679 . This potentially could be prevented by placement of a @entity1085 stent ( @entity1085 ). @entity1 AND METHODS: Between 11/2006 and 10/2007, a total of 73 @entity1 (50 male) aged 65 +/- 14 years underwent CSEMS placement for palliation of @entity3883 . In cases where CSEMS placement caused occlusion of the cystic duct, a 7 French transpapillary pigtail @entity1085 ( @entity1085 ) was inserted to prevent @entity2679 . RESULTS: Of the 73 @entity1 , 18 had a prior cholecystectomy; 34 had the CSEMS placed below the cystic duct insertion. In 19 out of the 21 @entity1 who had a CSEMS covering the cystic duct ostium, @entity1085 placement was attempted, which was successful in 11 individuals (58%). An attempt to access the @entity1085 was complicated by wire perforation of the cystic duct in three @entity1 ; one @entity1 requiring emergent cholecystostomy tube placement. None of the @entity1 who underwent successful @entity1085 placement developed @entity2679 . One @entity1085 dislodged and was repositioned. @entity2679 occurred in two (20%) of the ten @entity1 without @entity1085 who had a CSEMS covering the cystic duct. CONCLUSIONS: The ideal placement of a CSEMS is below the cystic duct insertion. Should the cystic duct ostium be occluded, placement of a @entity1085 should be considered to minimize the risk of @entity2679 .
