Background and study aims : Management of post-sphincterotomy perforations is variable, with some patients managed conservatively and other requiring surgery. Fully-covered self-expanding metal stents (FCSEMs) have been used in the past, but data is limited. The aim of this study was to report the clinical characteristics and outcomes following placement of anchored FCSEMSs for the immediate management of post-sphincterotomy perforation.
Patients and methods : All patients undergoing an ERCP procedure between June 2011 and December 2015 at our institution were reviewed for post-sphincterotomy perforation. All intra-procedurally recognized perforations underwent placement of FCSEMs with flexible anchoring fins and were included in this study. Data extracted included patient demographics, indication, peri-procedural details, clinical course and long-term outcome following anchored FCSEMS placement.
Results : A total of 15 patients (12 females, median age-66 years) with post-sphincterotomy perforation were included. Major indications included choledocholithiasis in 9 (60 %), and 5 (33.3 %) patients had intra-ampullary or periampullary diverticula. All patients underwent placement of FCSEMS without any complication and had immediate resolution of perforation as evidenced by decrease in fluoroscopic gas and lack of contrast extravasation. None of the patients became symptomatic or needed surgery with a median 2 days of hospitalization following the procedure. Stents were removed after a median of 30.5 days and no complications were noted during follow-up after stent removal.
Conclusions : Anchored FCSEMs are safe and effective for management of intra-procedurally recognized post-sphincterotomy perforations and obviates need for surgery.
