The EUS 2008 working group considered the development of equipment and methods to minimize the need for exchanging accessories and to facilitate insertion of multiple transmural stents during endoscopic ultrasound (EUS)-guided pseudocyst drainage as an important advance for therapeutic EUS. The authors aimed to describe their experience with EUS-guided pseudocyst drainage using a novel multiple-wire insertion technique facilitated by the double-lumen biliary cytology brush catheter.
The study enrolled 10 symptomatic patients undergoing EUS-guided pseudocyst drainage. The EUS-guided pseudocyst drainage was performed as a one-step procedure using graded catheter and balloon dilation of the cystgastrostomy tract and a novel multiple-wire insertion technique facilitated by a modified double-lumen biliary cytology brush catheter. The main outcome measured was technical success.
In this study, 10 patients with 11 pseudocysts underwent a EUS-guided pseudocyst using the novel multiple-wire insertion technique. Technical success, defined as successful achievement of access and drainage of pseudocysts, was achieved in all cases (100 %) with no procedural complications. Clinical success was achieved in all cases with complete resolution of pseudocysts.
The novel method of using a modified double-lumen biliary cytology brush catheter allows for a simple and safe one-step EUS-guided drainage of pseudocysts.
