Article Synopsis
  • The study compares single-operator (SO) and dual-operator (DO) approaches in treating chronic total occlusion (CTO) using percutaneous coronary intervention (PCI), noting that DO is suggested to handle the complexity of the procedure better.
  • Data from the Polish Registry of Invasive Cardiology Procedures between 2014 and 2020 reveals that DO was used in only 13% of cases, showing lower rates of puncture-site bleeding but similar technical success rates between SO (72.4%) and DO (71.2%).
  • The findings are preliminary due to the retrospective nature of the study, highlighting that DO was more common among patients with complex coronary diseases, but ultimately did not improve intervention success, only reducing

Background: Following therapeutic mammoplasty (TM), the contralateral breast may require a later balancing procedure to optimize shape and symmetry. The alternative is to offer patients simultaneous TM with immediate contralateral symmetrization via a dual-surgeon approach, with the goal of reducing costs and minimizing the number of subsequent hospital appointments in an era of COVID-19 surges. The aim of this cost-consequence analysis is to characterize the cost-benefit of immediate bilateral symmetrization dual-operator mammoplasty versus staged unilateral single operator for breast cancer surgery.

Background: Cholangioscopy provides direct intraductual imaging, which can enhance diagnostic efficacy during endoscopic retrograde cholangiopancreatography in patients with biliary strictures. This study aimed to review the diagnostic yield of different cholangioscopes for the diagnosis of malignant biliary stricture (MBS).

Methods: A comprehensive literature review was performed.

Wiring a side branch through a dual lumen microcatheter is typically performed in sequential fashion: the microcatheter position is modified, followed by wiring attempts, all performed by a single operator. We describe a dual operator technique, in which positioning of the dual lumen microcatheter and guidewire advancement are performed simultaneously. This method can be used for particularly challenging wiring scenarios.

Unlabelled: The usefulness of ultrasound guidance in peripheral intravenous access placement has yet to be established in children. In this prospective comparative study, we investigated success rates of intravenous access placement with ultrasound guidance in a pediatric emergency department. After a failed first attempt with the conventional technique, the second and third attempts were conducted using either the ultrasound guidance (a real-time, dual operator method) or the conventional technique.
