Background/aims: The aims of this study were to assess the feasibility and safety of emergency ERCP and pancreatic duct (PD) stenting in acute biliary pancreatitis (ABP) patients in whom biliary endoscopic sphincterotomy proved difficult, and to compare the clinical outcome of those patients having emergency ERCP without pancreatic stent.
Methodology: One hundred and ninety-one consecutive patients with ABP were included in this study. Patients were randomly assigned to either the stent group (n=78) or the no-stent group (n=113). In the stent group, 3-5Fr,5-7cm-long pancreatic stent insertion was initially applied and removed endoscopically 1-2 weeks post-ER-CP. All patients were hospitalized for medical therapy and were followed-up.
Results: Mean age, initial symptom-to-ERCP times, Glasgow severity scores and peak amylase and CRP levels at initial presentation were not significantly different in the stent group vs. the no-stent group, and the selective biliary cannulation was achieved in 80% of the stent group and in 94% of the no-stent group (p=0.15). More importantly, the complication rate was significantly lower in the stent group (7.7% vs. 31.9%). There was no difference in mortality between the two groups statistically(1.3% vs. 3.5%).
Conclusions: Pancreatic duct stent-ing is a safe and effective procedure that may afford sufficient PD decompression to reverse the process of ABP, show better outcomes as compared to no-stent group. It is recommended to reduce the incidence of the complication in the emergency ERCP of ABP but difficult sphincterotomy. However, further prospective trials are needed.

Objectives: Surgery is the only treatment for congenital choanal atresia (CCA). It is crucial to avoid postoperative restenosis or re-occlusion of the neo-choana. This study investigated the efficacy of a navigation-assisted endoscopic endonasal U-flap technique and a bioabsorbable steroid-eluting stent for CCA repair.

Background: Type 2 diabetes mellitus (T2DM) patients with small-diameter stents (SDS), that are equal to or less than 2.5 mm in diameter, face increased risks of restenosis and complications. This study aimed to evaluate the 1-year follow-up to assess the rate of major adverse cardiac events (MACE) and bleeding risk between ticagrelor and clopidogrel in T2DM patients after SDS implantation.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.
Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.

Article Synopsis
- The study evaluates the safety and effectiveness of the Zenith Dissection Endovascular System (ZDES) against traditional stent grafts for repairing acute complicated Type B Aortic Dissection (AcTBAD).
- A retrospective analysis of 32 patients revealed that the ZDES group experienced fewer postoperative adverse events (12 vs. 37), demonstrating better outcomes in false lumen thrombosis at 6 months and lower 3-year mortality rates.
- Despite some patients needing secondary interventions in the ZDES cohort due to aortic growth, overall results suggest the ZDES may offer improved safety and efficacy compared to traditional methods.
Cardioprotection exerted by intravenous statin at index myocardial infarction event attenuates cardiac damage upon recurrent infarction.

Aims: Recurrent acute myocardial infarction (RE-AMI) is a frequent complication after STEMI, and its association with stent thrombosis can be life-threatening. Intravenous atorvastatin (IV-atorva) administration during AMI has been shown to limit infarct size and adverse cardiac remodeling. We determined by cardiac magnetic resonance (CMR) whether the cardioprotection exerted by IV-atorva at the index AMI event translates into a better prognosis upon RE-AMI in dyslipidemic pigs.
