Core Tip
Core Tip: This retrospective study focused on the different drainage techniques using endoscopic retrograde cholangiopancreatography for malignant hilar biliary obstruction. It highlighted the benefits of parallel drainage, particularly when performed simultaneously using ultra-thin delivery devices. This resulted in a clear advantage in terms of technical success and reduced the risk of complications associated with technical failure, which was more frequently observed in the case of sequential drainage, especially in a “side by side” fashion.
