“…Moreover, the brush will accommodate two 0.035-inch wires, unlike the cannula, which accommodates a 0.035-inch wire and a 0.025-inch wire. 2 Nonetheless, the availability of endoscopic accessories is center-dependent, and this is a motivation for the off-label modification of available equipment to address complex clinical scenarios.…”

“…1 More recently, a doublelumen catheter specifically designed for the simultaneous placement of 2 guidewires has been released, but its distribution is currently limited to Japan (personal communication; Piolax Medical Devices, INC., Yokohama, Kanagawa, Japan; July 8, 2020). 2 We describe a simple modification of an available cytology brush catheter to facilitate the placement of a second guidewire and demonstrate its application in the management of patients in 3 distinct scenarios (Video 1, available online at www.giejournal.org).…”

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. (VideoGIE 2020;-:1-5.

“…However, this bent scope shape reduces the forward push force during device insertion, and in the worst case, the scope may be pushed back, and the guidewire may be dislodged from the bile duct. Shiomi et al [ 27 ] and Nakai et al [ 28 ] reported the usefulness of the “Double guidewire technique” using a double lumen catheter (Uneven Double Lumen Cannula [UDLC]; Piolax Medical Device, Kanagawa, Japan), which allows a second 0.035 inch guidewire to be inserted adjacent to the first 0.025 inch guidewire ( Figure 4 ). This technique improves the stability of the scope during device insertion and allows the use of the stiffer second guidewire if necessary.…”

Currently, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is widely performed worldwide for various benign and malignant biliary diseases in cases of difficult or unsuccessful endoscopic transpapillary cholangiopancreatography (ERCP). Furthermore, its applicability as primary drainage has also been reported. Although recent advances in EUS systems and equipment have made EUS-HGS easier and safer, the risk of serious adverse events such as bile leak and stent migration still exists. Physicians and assistants need not only sufficient skills and experience in ERCP-related procedures and basic EUS-related procedures such as fine needle aspiration and pancreatic fluid collection drainage, but also knowledge and techniques specific to EUS-HGS. This technical review mainly focuses on EUS-HGS with self-expandable metal stents for unresectable malignant biliary obstruction and presents the latest and detailed tips for safe and successful performance of the technique.

“…Guidewire advance toward the hilum is sometimes difficult in EUS‐HGS. In such a case, a rotatable sphincterotome could be useful with a double‐guidewire technique, in which one guidewire is left in the bile duct to keep the biliogastric fistula 5 …”
