Abstract
OMODEO, Mariana et al. Insertion of fully covered self-expanding metal stents in benign biliary diseases. Rev. esp. enferm. dig. [online]. 2018, vol.110, n.1, pp.30-34. ISSN 1130-0108. https://dx.doi.org/10.17235/reed.2017.5092/2017.
Introduction:
Benign biliary diseases are traditionally treated using plastic stents. However, fully covered self-expanding metal stents are currently gaining acceptance for the treatment of these pathologies.
Objective:
To assess the effectiveness and complications associated with the placement of temporary endoscopic fully covered self-expanding metal stents for the treatment of benign biliary diseases.
Materials and methods:
This was a retrospective and observational study using a prospective database from a tertiary care center from March 2012 to May 2016. Some patients that had a fully covered metal stent due to a benign biliary disease were also included. The indications, resolution, technical success rates and adverse events were documented.
Results:
31 patients were included with a total of 34 stents inserted. The indications were as follows: 8 (25%) post cholecystectomy biliary stenoses, 11 (31%) large or multiple choledocholithiasis, 3 (8.3%) biliary fistulas, 2 (6%) post-liver transplant stenoses, 2 (8.3%) papillary stenoses, 2 (6%) perforations and 2 (6%) bleeds. The global resolution success rate of the stents for all pathologies was 88%, this included 87.5% (7/8) in post cholecystectomy stenoses, 73% (8/11) in large choledocholithiasis and 100% for the remaining indications. Thirty-three of 34 stents were removed after an average of 133 days (ranging from 10 to 180 days). No complications were registered.
Conclusion:
Fully covered self-expanding metal stents are an effective and reliable alternative for the resolution of benign biliary diseases.
