Background: Dilation is the standard of care for recurrent benign esophageal strictures (BES). Biodegradable stents may prolong the effect of dilation and reduce recurrences. Efficacy and safety of dilation and biodegradable stent placement early in the treatment algorithm of recurrent BES were compared.

We aimed to compare EMP and EGDP in outpatients, ward patients, and critically ill patients with normal upper GI anatomy.
Methods: In 3 centers with no prior experience in EMP, patients were randomized to placement of a single-lumen nasoduodenal feeding tube either with EGDP or EMP.
Objective: For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.
Patients And Methods: This randomized multicenter trial included 219 patients who were randomized to receive plastic stent (n=73) or SEMS [uncovered (n=75) and covered (n=71); n=146] placement.
Background & Aims: Endoscopic stents are placed for palliation of extrahepatic bile duct obstruction. Although self-expandable metal stents (SEMS) remain patent longer than plastic stents, they are more expensive. We aimed to evaluate which type of stent (plastic, uncovered SEMS [uSEMS], or partially covered SEMS [pcSEMS]) is the most effective and we assessed costs.

Objective: To evaluate the efficacy of a novel FCSEMS with antimigration features.
Article Synopsis
- A new self-expanding metal stent with bilateral flanges was tested for draining pancreatic fluid collections (PFCs) via endoscopic ultrasound (EUS), focusing on its effectiveness and safety.
- In a study with 61 patients, the stent was successfully placed in 98% of cases, and clinical success rates were high at 93% for pancreatic pseudocysts and 81% for walled-off necrosis (WON).
- While there were some complications (9%), the overall findings suggest that using this stent for EUS-guided drainage is both feasible and effective.
Background And Study Aims: A new esophageal stent with two anti-migration features was developed to minimize migration. The aim of this study was to evaluate the clinical efficacy and safety of this stent in patients with malignant dysphagia.
Patients And Methods: A total of 40 patients with dysphagia due to a malignant obstruction of the esophagus were prospectively enrolled in this cohort study.
Endoscopic placement of self-expandable metal stents (SEMS) has emerged as a palliative treatment for patients with malignant gastric outlet obstruction (GOO). Recently, a new partially covered "big cup" SEMS has been developed to prevent both stent migration and tissue ingrowth. The aim of the study was to evaluate safety and efficacy of this SEMS in a cohort of patients with incurable malignant GOO.

In this study we evaluated a recently developed functional flow cytometry based assay for the analysis of platelet function in chronic kidney disease.
Methods: Platelet reactivity was measured using flow cytometric analysis.
