Mechanical versus electrocautery dilator for EUS-guided biliary drainage

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Patients who require endoscopic ultrasound-guided biliary drainage after failed ERCP will undergo tract dilation with either a mechanical dilator or an electrocautery dilator and be followed for bleeding and other complications. The procedure uses EUS to puncture the dilated bile duct, place a guidewire, dilate the tract, and insert a stent for drainage. The primary focus is comparing post-dilation bleeding rates between the two dilation methods, along with procedural success and other adverse events. Data so far are mostly retrospective, so prospective comparison in this population aims to clarify relative safety.
