A systematic review of 47
trials including 1,116 patients with extrahepatic BBS showed
that placing multiple plastic stents had higher clinical success
(94.3% vs 59.6%) and fewer adverse events (20.3% vs
36.0%) compared with placement of a single plastic stent,
respectively.
Treatment of BBS with plastic stents typically involves
3 monthly stent exchanges, with placement of an increasing
number and/or diameter of stents for up to 12 months.
Alternatively, the maximal number of stents can be inserted
at the index ERCP, allowing reduced frequency of ERCP and
stent exchange.
