Objective: To conduct a network meta-analysis (NMA) in comparing biliary stents types' outcomes and complications in unresectable MBO. Methods: The study was conducted in accordance with the PRISMA and NMA extension . Comprehensive searches of the Cochrane Library, MEDLINE, and Scopus were done analyzing randomized controlled trials that included subjects with unresectable malignant biliary obstructions that underwent biliary stents placement from any approaches. The types of stents that included were full-covered metal (FMS), partially-covered metal (PMS), uncovered metal (UMS), plastic (PLS), Iodine-125 seeds strands (IRS), antireflux (ARS), and paclitaxel-coated (PXS) stents. The outcome parameters were clinical success, median patency duration, medial survival, and early 30-day mortality. The complications included were stent occlusion, stent migration, cholangitis, cholecystitis, pancreatitis, hemorrhage, and hemobilia. The NMA will be done based on Bayesian method, Markov Chain Monte Carlo algorithm, using BUGSnet package in R studio. Transivity was controlled by methods and consistency of the NMA will be fitted by deviance information criterion. Data analysis in NMA were presented in Sucra plot, league table, and forest plot. Result: Thirty-six RCTs were included with 3502 subjects. ARS had the best clinical success and longest median patency. However, it was associated with higher rate of complications. IRS had a good clinical success (RR 1.63; 95%CI 0.67-6.25), long median patency (MD 21.14;, and high significant survival rate (MD 69.89; 95%CI 22 to 117.57) compared to others stents. It was associated unsignificant complications of cholecystitis, hemobilia, and hemorrhage. Conclusion: Iodine-125 seeds strands had the promising good outcome and tolerated complications among others and should be considered as a standard stent to be used in unresectable malignant biliary obstructions.

“…PLLA Self‐expanding braided stents have good flexibility and are usually used in tortuous and highly mobile blood vessels, such as peripheral vessels and bile ducts 4,7–12 . Furthermore, by appropriately designing the parameters of PLLA braided stents, comparable radial mechanical properties to those of metal stents can be achieved 13,14 . These advantages make absorbable PLLA self‐expanding braided stents to be an important research direction currently.…”

Stress relaxation of poly (L‐lactic acid) (PLLA) braided stents generated after crimping will significantly influence the radial properties of the stents, due to the viscoelasticity of PLLA. In particular, the environmental temperature and duration in the relaxation process are two vital effects on these radial performances. Thereby, a serious of crimping temperatures and holding durations were adopted in this study to investigate their influence on the radial properties of stents. The radial properties of the stent, including peak compression force, chronic outward force and energy loss, were characterized by radial mechanical tests. Results showed that the stress relaxation rates of PLLA braided stents increased with the increase of the crimp‐holding temperature and time. Specifically, the stress relaxation rates at 25, 37 and 42°C were 22.81%, 28.41% and 36.10% at hold time of 300 s. Moreover, the increase of stress relaxation can reduce chronic outward force of stents, which will furtherly cause complications such as insufficient supporting and the shift of stent and so on. Therefore, decreasing the crimp‐holding temperature and duration of stents is an effective method to reduce the stent stress relaxation. This work provides experimental references for the comprehensive evaluation of mechanical properties of PLLA braided stent in clinical application.
