Objectives: Efficiency evaluation of percutaneous metallic stents in palliative treatment of malignant biliary obstruction.
Methods: One hundred sixteen percutaneous metallic stents were implanted in 80 patients with malignant biliary obstruction. Thirty-five patients had hilar obstruction, 32 patients obstruction of the common bile duct and 12 patients obstruction of a bilioenteric anastomosis.
Results: Adequate biliary drainage was achieved in 79 patients. Early complications occurred in 23.75% of patients; 12.5% of patients died within 30 days. The procedure-related mortality rate was 5%; 18.75% of patients showed recurrent jaundice after an average of 175 days.
Conclusion: Percutaneous metallic stents are an efficient means of treating malignant biliary strictures, particularly of upper biliary obstructions. However, this treatment has risks and limits that require careful patient recruitment.

Prognostic factors for survival in patients with advanced cholangiocarcinoma treated with percutaneous transhepatic drainage.

Biliary drainage is then one of the necessary procedures to help patients suffering from icterus to reduce serum bilirubin levels and relieve symptoms. The aim of this study was identifying risk factors for survival in patients with cholangiocarcinoma (CCA) treated with percutaneous transhepatic biliary drainage (PTBD) and to develop a simple scoring system predicting survival from PTBD insertion. This single-centre retrospective study included 175 consecutive patients undergoing PTBD for extrahepatic CCA (perihilar and distal).

Background: The risk-benefit ratio of the Absorb bioresorbable vascular scaffold (BVS) may vary before and after 3 years, the time point of complete bioresorption of the poly-L-lactic acid scaffold.
Objectives: The aim of this study was to determine the time-varying outcomes of the Absorb BVS compared with cobalt-chromium everolimus-eluting stents (EES) from a large individual-patient-data pooled analysis of randomized trials.
Methods: The individual patient data from 5 trials that randomized 5,988 patients undergoing percutaneous coronary intervention to the Absorb BVS vs EES with 5-year follow-up were pooled.
Thermosensitive-based synergistic antibacterial effects of novel LL37@ZPF-2 loaded poloxamer hydrogel for infected skin wound healing.

Trauma healing is the process of healing after the body has been subjected to an external force and the skin and other tissues have become dissected or defective, showing the synergistic effect of various processes. Therefore, the investigation of innovative wound dressings has significant research and clinical implications. In this study, we constructed a zinc based metal-organic framework (MOF) and loaded with antimicrobial peptide LL37 to prepare LL37@ZPF-2 (ZPF = zeolite pyrimidine backbone), which was subsequently integrated with Poloxamer 407 to fabricate LL37@ZPF-2 thermosensitive hydrogel.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.
