Core Tip

Core tip: The method of transgastrostomic endoscopy using an ultrathin endoscope has been reported in terms of its safety and various advantages. A 6F delivery system uncovered-type self-expanding metal stent (SEMS) has been developed, and this SEMS is able to pass through an endoscopic working channel at least 2.0 mm in diameter. To our knowledge, this is the first reported evaluation of the performance of biliary drainage for malignant stricture using a 6F introducer SEMS with an ultrathin endoscope through the percutaneous endoscopic gastrostomy stoma.
