What is A Novel Laser‐cut Fully Covered Metal Stent with Anti‐reflux Valve in Patients with Malignant Distal Biliary Obstruction Refractory to Conventional Covered Metal Stent about?
## Background: Stenting against recurrent biliary obstruction (rbo) after placement of covered metal stent (cms) for distal malignant biliary obstruction (mbo) is still challenging. this study investigated the feasibility of a novel laser-cut fully cms with anti-reflux valve in patients with distal mbo refractory to conventional cms. ## Methods: Patients who underwent duckbill-type metal stent (dms) placement between june 2019 and may 2020 were included. early complications, causes of rbo including non-occlusion cholangitis, and time to rbo (trbo) were evaluated. trbo of dms was also compared with that of previous cms. ## Results: Thirty patients were included: pancreatic cancer/metastatic lymph nodes in 29 patients/one patient; duodenal stenosis in 13 patients. technical and functional success were achieved in all patients. mild cholangitis and mild pancreatitis developed in each one. median follow-up period was 167 days (range, 23-527 days). rbo occurred in nine patients (30%): sludge formation in four patients, hemobilia in one patient, symptomatic distal stent migration in three patients, and non-occlusion cholangitis in one patient. trbo of dms was significantly longer than th
