title: Endoscopic ultrasound-guided choledochoduodenostomy with a lumen-apposing, self-expandable fully covered metal stent for palliative biliary drainage.
abstract: In addition to the poor prognosis associated with pancreatic adenocarcinoma, it can also lead to several other conditions including obstructive jaundice that can affect a patient's quality of life. This is a major concern in non-operative patients where palliation is considered the main therapeutic goal. Traditionally, there are several ways to pursue palliative biliary drainage including endoscopic methods, a variety of surgical procedures, and percutaneous techniques. Generally, endoscopic methods such as endoscopic retrograde cholangiopancreatography (ERCP) with transpapillary stent placement are considered first-line therapies. Unfortunately, ERCP is not always possible due to several potential reasons. Although endoscopic ultrasound-guided biliary puncture has been well described for several years, there are limitations to its usefulness in biliary drainage, in part due to complication concerns. However, more recently a lumen-apposing, self-expandable fully covered metal stent has been employed for such situations. We describe two cases in which this type of stent was used in patients for palliative biliary drainage in pancreatic adenocarcinoma where standard ERCP was not feasible. In both cases, stent deployment was successful without immediate complications related to the procedure or the stent. Furthermore, the main goal of these therapies was palliation and in both cases the patient chose this procedure for quality of life reasons. In the future, randomized trials are needed to better define the long-term effectiveness and safety of these stents compared to more standard therapies.
