Abstract
BACKGROUND: Biliary complications are a serious source of morbidity after orthotopic and living-related liver transplantation. Endoscopic retrograde cholangiography (ERC) is the gold standard for patients with duct-to-duct anastomosis because it allows a direct approach for interventional procedures. A retrospective study showed results of a sequential multistenting protocol, without stent removal/exchange, with promising results. We conducted a prospective analysis to assess the clinical success, recurrence rate, and adverse event rate related to this protocol.
METHODS: From May 2012 to April 2018, all consecutive patients with a diagnosis of anastomotic stenosis following liver transplantation were enrolled in the study, and were followed for a period of at least 6 months after the last ERC. During the first ERC, a maximum number of plastic stents (10 Fr) were placed. In subsequent ERCs, scheduled every 3 months up to a maximum of 1 year, additional stents were inserted, as many as possible, without removing the previously placed stents.
RESULTS: From May 2012 to May 2018, 87 patients were included in the study and treated with a sequential multistenting protocol. The mean number of stents placed was 3.7 (SD 1.0). Clinical success (stricture resolution and normalization of cholestasis) was achieved in 86 patients (98.9 %). Seven patients (8.0 %) developed complications. Recurrence was recorded in seven patients (8.0 %) after a mean of 992.7 days (SD 622.1).
CONCLUSIONS: This study represents the first prospective demonstration of the efficacy and safety of a sequential multistenting protocol. A key limitation of the study is the lack of a comparative group treated according to the traditional stent exchange approach. © Georg Thieme Verlag KG Stuttgart · New York.
