The underutilization of EUS-guided biliary drainage: Perception of endoscopists in the East and West.

BACKGROUND AND OBJECTIVES

EUS-guided biliary drainage (EUS-BD) is increasingly utilized to manage unresectable malignant biliary obstruction after a failed ERCP. However, there is no data on how endoscopists perceive EUS-BD. The aim of this study was to investigate the perception of endoscopists on EUS-BD.

PATIENTS AND METHODS

A survey questionnaire of six topics with 22 survey statements was developed. A total of 17 pancreatobiliary endoscopists (10 from East and 7 from West) were invited to survey. The participants were asked to answer the multiple choice questionnaire and give comments. The opinions of the participants for individual survey statements were assessed using 5-point Likert scale.

RESULTS

All participants completed the survey. The endoscopists had a trend to perceive EUS-BD as a procedure indicated after a failed ERCP. Various EUS-BD methods were regarded as having different efficacy and safety. The superiority of EUS-BD over percutaneous transhepatic BD (PTBD) with regard to efficacy, procedure-related adverse events, and unscheduled re-intervention was not in agreement.

CONCLUSIONS

EUS-BD was not yet perceived as the initial procedure to relieve the unresectable malignant biliary obstruction. Various EUS-BD methods were regarded as having different efficacy and safety. The superiority of EUS-BD over PTBD was not in agreement. Refining the procedure, developing dedicated devices, and gaining expertise in the procedure are necessary to popularize EUS-BD.
