Background and Aims: Serial stent placement may be necessary during endoscopic interventions, but the passage of a guidewire alongside an initial stent can be challenging, time-consuming, and sometimes unsuccessful. We describe a modification of a cytology brush catheter to allow simultaneous placement of 2 guidewires to facilitate serial stent placement and demonstrate its application in different scenarios., Methods: This is a retrospective series of 3 patients with different conditions (acute cholecystitis, pancreas pseudocyst, and severe biliary stricture) in whom placement of a second guidewire facilitated serial stent placement. A step-by-step demonstration of the technique is provided., Results: Serial stent placement was successful in all patients without adverse events., Conclusions: A modified cytology brush catheter can be used to deliver 2 guidewires simultaneously during ERCP and EUS procedures. This technique may improve procedural efficiency, maintain a safety track, and augment therapy in certain situations., (© 2020 American Society for Gastrointestinal Endoscopy.

Background and Aims: Endoscopic stent placement in luminal GI strictures is not always feasible with traditional stents. For example, standard luminal stent delivery catheters may not successfully traverse severe strictures, and enteral stents may not be suitable for sites in the GI tract that pose significant adverse events if downstream migration were to occur. We demonstrate extrabiliary applications of specialized, fully covered antimigration biliary metal stents., Methods: This is a retrospective series of 4 patients with different benign and malignant luminal GI strictures who underwent placement of fully covered antimigration biliary metal stents in different configurations as a bridge or destination therapy., Results: Luminal obstruction resolved without adverse events in all cases., Conclusions: Although off label, extrabiliary use of these stents can successfully address scenarios of complex luminal pathology. To compensate for the small stent caliber, two stents may be placed side by side in a double-barrel configuration. Strict diet modifications are necessary when applying this therapeutic paradigm., (© 2020 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.)
