Objective: The purpose of this study is a prospective evaluation of the ease of implantation, long-term patency, indication of good oesophageal stent placement and related complications in patients due to obstructive malignant diseases. The clinical efficacy of these techniques is also examined.
Materials And Methods: A total of 123 patients with severe oesophageal obstruction diagnosed between 1999 and 2008 were selected for stent placement. The following stents were used: Wallstent; Ultraflex; Medwark; Endotechnik; Wilson Cook (plastic); and Z stents.
Results: The stent was successfully placed in the diseased oesophagus in all 123 patients. The stent implantation was more than 95% effective but the stent patency and the patients' life quality was low due to both progression of the disease and stent performance. Stents did increase life expectancy but performance was limited.
Conclusions: Stent placement is safe and effective for the primary palliation of patients with inoperable malignant oesophageal obstruction. Even if the stent price is relatively high the costs are offset due to earlier patient discharged from hospital. Stent and patient related problems persist and may require additional intervention. New innovations in stent design are needed to reduce the risk of stent-related complications.

Biodegradable Stents in the Treatment of Arterial Stenosis.

Arterial diseases (ADs) are a significant health problem, with high mortality and morbidity rates. Endovascular interventions, such as balloon angioplasty (BA), bare-metal stents (BMSs), drug-eluting stents (DESs) and drug-coated balloons (DCBs), have made significant progress in their treatments. However, the issue has not been fully resolved, with restenosis remaining a major concern.

Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates.

Background And Aim: Stent placement for biliary drainage in patients with malignant hilar biliary obstruction (MHBO) has been a topic of long-standing debate, and the best approach remains controversial. Therefore, we aimed to evaluate the efficacy, safety, and removability of multi-hole fully covered self-expandable metal stents (MH-FCSEMSs) in a preclinical experiment using swine hilar bile duct obstruction (HBDO) models and to assess the feasibility and safety of stent placement in patients with MHBO.
Methods: Three minipigs underwent endoscopic retrograde cholangiopancreatography (ERCP)-guided endobiliary-radio frequency ablation (EB-RFA) to establish Bismuth type II hilar bile duct stenosis models.
Magnetic resonance angiography in diagnostic long-term follow-up of primary patency of the MOTIV drug-eluting bioresorbable vascular scaffold in the region below the knee: 5 years of experience.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.

Background: Rising antimicrobial resistance (AMR) is an acute public health emergency impeding the clinical efficacy of surgical interventions. Biliary stent placement is one of the routine surgical procedures that rarely lead to infections that are empirically managed by broad-spectrum β-lactams and fluoroquinolones. Critical priority pathogens, such as carbapenem-resistant Escherichia coli challenge treatment outcomes and infection prevention.
