Successful Management of Benign Biliary Strictures With Fully Covered Self-Expanding Metal Stents
BACKGROUND & AIMS:
Fully covered self-expanding metal stents (FCSEMS) are gaining acceptance for the treatment of benign biliary strictures. We performed a large prospective multinational study to study the ability to remove these stents after extended indwell and the frequency and durability of stricture resolution.
METHODS:
In a nonrandomized study at 13 centers in 11 countries, 187 patients with benign biliary strictures received FCSEMS. Removal was scheduled at 10-12 months for patients with chronic pancreatitis or cholecystectomy and at 4-6 months for patients who received liver transplants. The primary outcome measure was removal success, defined as either scheduled endoscopic removal of the stent with no removal-related serious adverse events or spontaneous stent passage without the need for immediate restenting.
RESULTS:
Endoscopic removal of FCSEMS was not performed for 10 patients because of death (from unrelated causes), withdrawal of consent, or switch to palliative treatment. For the remaining 177 patients, removal success was accomplished in 74.6% (95% confidence interval [CI], 67.5%-80.8%). Removal success was more frequent in the chronic pancreatitis group (80.5%) than in the liver transplantation (63.4%) or cholecystectomy (61.1%) groups (P = .017). FCSEMS were removed by endoscopy from all patients in whom this procedure was attempted. Stricture resolution without restenting upon FCSEMS removal occurred in 76.3% of patients (95% CI, 69.3%-82.3%). The rate of resolution was lower in patients with FCSEMS migration (odds ratio, 0.22; 95% CI, 0.11-0.46). Over a median follow-up period of 20.3 months (interquartile range, 12.9-24.3 mo), the rate of stricture recurrence was 14.8% (95% CI, 8.2%-20.9%). Stent- or removal-related serious adverse events, most often cholangitis, occurred in 27.3% of patients. There was no stent- or removal-related mortality.
CONCLUSIONS:
In a large prospective multinational study, removal success of FCSEMS after extended indwell and stricture resolution were achieved for approximately 75% of patients. ClincialTrials.gov number, NCT0101439

Fully covered self-expanding metal stents for benign biliary stricture after orthotopic liver transplant: 5-year outcomes
Background and Aims: Minimally invasive treatments of anastomotic benign biliary stricture (BBS) after orthotopic liver transplantation (OLT) include endoscopic placement of multiple plastic stents or fully covered self-expandable metal stents (FCSEMSs). No multiyear efficacy data are available on FCSEMS treatment after OLT. Methods: We prospectively studied long-term efficacy and safety of FCSEMS treatment in adults aged 6518 years with past OLT, cholangiographically confirmed BBS, and an indication for ERCP with stent placement. Stent removal was planned after 4 to 6 months, with subsequent follow-up until 5 years or stricture recurrence. Long-term outcomes were freedom from stricture recurrence, freedom from recurrent stent placement, and stent-related serious adverse events (SAEs). Results: In 41 patients, long-term follow-up began after FCSEMS removal (n = 33) or observation of complete distal migration (CDM) (n = 8). On an intention-to-treat basis, the 5-year probability of remaining stent-free after FCSEMS removal or observation of CDM was 48.9% (95% confidence interval [CI], 33.2%-64.7%) among all patients and 60.9% (95% CI, 43.6%-78.2%) among 31 patients with over 4 months of FCSEMS indwell time. In 28 patients with stricture resolution at FCSEMS removal or observed CDM (median, 5.0 months indwell time), the 5-year probability of no stricture recurrence was 72.6% (95% CI, 55.3%-90%). Sixteen patients (39%) had at least 1 related SAE, most commonly cholangitis (n = 10). Conclusions: By 5 years after temporary FCSEMS treatment of post-OLT BBS, approximately half of all patients remained stent-free on an intention-to-treat basis. Stent-related SAEs (especially cholangitis) were common. FCSEMS placement is a viable long-term treatment option for patients with post-OLT BBS. (Clinical trial registration number: NCT01014390.
