Use of a double-lumen cytology brush catheter to allow double-guidewire technique for endoscopic interventions.

ABSTRACT:

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.
