Endoscopic fenestration of duodenal stents using argon plasma to facilitate ERCP.
Topazian M, Baron TH
Gastrointest Endosc. 2009;69(1):166.
BACKGROUND: The presence of a duodenal stent may hinder attempts at ERCP for treatment of malignant biliary obstruction.
OBJECTIVE: We describe 2 patients in whom endoscopic fenestration of indwelling duodenal stents with an argon plasma coagulator facilitated successful ERCP.
DESIGN: Single-center retrospective case series.
SETTING: Tertiary-referral center.
PATIENTS: Both patients had unresectable biliary malignancy with both duodenal and biliary obstruction.
INTERVENTION AND RESULTS: Windows were cut into indwelling duodenal stents with argon plasma, which exposed the underlying papilla and allowed successful ERCP and stent placement.
LIMITATIONS: Retrospective study and the small sample size.
CONCLUSIONS: Fenestration of duodenal stents using argon plasma is a simple technique that can facilitate ERCP.
