Safety and efficacy of ultra-tapered mechanical dilator for EUS-guided hepaticogastrostomy and pancreatic duct drainage compared with electrocautery dilator (with video).

ABSTRACT:

Background and objectives

Successful tract dilation is one of the most important steps to accomplish EUS-guided drainage. Although mechanical dilation is safer than electrocautery dilation, no dedicated mechanical dilator (MD) is currently available. Thus, we developed a new ultra-tapered MD for EUS-guided drainage. This study aimed to evaluate the safety and usefulness of this novel MD.

Patients and methods

Consecutive patients who underwent EUS-guided hepaticogastrostomy (EUS-HGS) or EUS-guided pancreatic duct drainage (EUS-PD) at two centers were included in the study. Dilation of the needle tract was initially performed with a diathermic sheath or the ultra-tapered MD. Technical success and adverse events were assessed.

Results

Sixty-four patients (mean age = 68.9
