OBJECTIVE: The purpose of this study was to evaluate the long-term clinical efficacy of temporary placement of covered retrievable stents in the management of recurrent @entity3832 . MATERIALS AND METHODS: During the period December 1998-December 2005, 32 @entity1 and one adolescent @entity1 (mean age, 48.6 years; range, 16-73 years) with recurrent @entity3832 underwent fluoroscopically guided insertion of a total of 68 stents. @entity1 without complications underwent elective stent removal 2 or 4 months after stent insertion. Rates of clinical success (long-term clinical and radiographic resolution of @entity3832 ) were assessed. The Mann-Whitney U test was used to compare the duration of stent placement in @entity1 with long-term clinical resolution with that in @entity1 with stricture relapse. RESULTS: Clinical success was achieved in 18 (55%) of the 33 @entity1 . The mean duration of stent placement in @entity1 with clinical success was significantly different from that in @entity1 who had recurrences (p < 0.0001). Stricture relapse did not occur in only four (20%) of 20 cases of stent placement for 2 months. All 14 stent placements lasting at least 4 months resulted in long-term resolution after a mean follow-up period of 3.6 years. The most common complications necessitating early stent removal were stent migration (33.8% of stents) and tissue @entity1373 (20.6% of stents). CONCLUSION: Placement of a covered retrievable stent for a minimum of 4 months is effective in inducing long-term resolution of refractory @entity3832 . Stent migration remains the largest obstacle in achieving adequate duration of stent placement.
