Efficacy and Safety of HANAROSTEN® HOT Plumber™ With Z-EUSIT™ for Pancreatic Pseudocyst Drainage (ZEUS) 20 관찰 연구
The goal of this prospective, single-center observational study is to evaluate the safety and effectiveness of the HANAROSTEN® HOT Plumber™ with Z-EUSIT™ for draining pancreatic pseudocysts.
The main questions the study aims to answer are:
- Does the device reduce the size of pancreatic pseudocysts by at least 50% and improve associated symptoms within 30 to 60 days?
- Can the stent be successfully placed, retained...
This prospective, single-center observational study aims to evaluate the safety and effectiveness of the HANAROSTEN HOT Plumber with Z-EUSIT for pancreatic pseudocyst drainage. The study will assess clinical success, defined as a reduction of at least 50% in pseudocyst size accompanied by symptom improvement, as well as technical success, device retention, lumen patency, and adverse events.

실험적Single Intervention Group Participants will undergo endoscopic ultrasound-guided drainage of pancreatic pseudocysts using the HANAROSTEN® HOT Plumber™ with Z-EUSIT™. | HANAROSTEN® HOT Plumber™ with Z-EUSIT™ An electrocautery-enhanced lumen-apposing metal stent designed for the drainage of pancreatic pseudocysts. The stent is delivered using a system that allows for single-step deployment without the need for guidewire exchanges or tract dilation. |

Clinical Success | Reduction of pancreatic pseudocyst size by at least 50% with improvement in associated symptoms. | Within 30 or 60 days after stent placement |
| 결과변수 | 측정값 설명 | 시간 범위 |
|---|---|---|
Technical Success - Stent Placement | Successful deployment of the stent at the intended site. | During procedure |
Technical Success - Stent Removal | Successful removal of the stent after pseudocyst resolution, confirmed by endoscopic confirmation of complete stent removal without residual fragments. | Within 30 or 60 days after placement |
Stent Retention | Retention of the stent in the intended location without migration until removal. | Within 30 or 60 days after placement |
Lumen Patency | Maintenance of an open lumen allowing fluid drainage until stent removal. | Within 30 or 60 days after placement |
Procedure Duration | Time from initial needle puncture to full deployment of the stent. | During procedure |
Adverse Events | Incidence of complications such as bleeding, infection, perforation, stent migration, tissue injury, or other adverse events. | From procedure day until one month after stent removal |
