Conversion to EUS-guided internal gallbladder drainage from percutaneous cholecystostomy: A successful case using a novel plastic stent

摘要

For acute cholecystitis with high surgical risk, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has shown high clinical and technical success rates. Dilation of the punctured fistula is a technically challenging aspect of EUS-GBD. Over-dilation makes stent insertion easier; however, it increases the risk of bile leakage. Currently, the endoscopic devices available for EUS-GBD are limited, which presents device-related shortcomings. When the stent cannot pass through the dilated fistula, the deployment of a conventional double-pigtail plastic stent requires discarding of the stent and re-puncturing of the gallbladder. Recently, a novel integral double-pigtail plastic stent tied with a pusher catheter that allows the stent to be pulled back on insertion failure was developed. Here, we describe a patient in whom EUS-GBD was successfully performed using this novel stent that enables adjustment during dilation, making EUS-GBD safer.
