Summary
A novel detachable snare enables endoscopic ligation for effective hemostasis during large polyp removal. This minimally invasive technique significantly reduces bleeding risks, improving patient outcomes in endoscopic resections.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Medical Devices
Background:
- Endoscopic removal of large polyps and elevated lesions can be complicated by bleeding.
- Hemostasis is crucial for safe and effective endoscopic resection.
- Existing methods may have limitations in controlling hemorrhage during these procedures.
Purpose of the Study:
- To evaluate the efficacy of a new detachable snare for endoscopic ligation in achieving hemostasis.
- To assess the device's utility in preventing bleeding before resection and controlling active hemorrhage.
- To determine the safety and success rates of this ligation technique in a clinical setting.
Main Methods:
- A detachable snare (Olympus Ligating Device) was used for endoscopic ligation in 80 patients.
- The procedure involved ligating large elevated lesions prior to resection (71 patients) or controlling hemorrhage (9 patients).
- Lesions included polyps and submucosal tumors, with diameters ranging from 15-40 mm.
Main Results:
- Complete prevention of hemorrhage was achieved in 88.7% of patients undergoing preventive ligation before resection.
- Endoscopic resection was successfully performed in 98.6% of cases when ligation was combined with HX-3L clips.
- Complete hemostasis was achieved in all 9 patients with bleeding lesions without complications.
Conclusions:
- The detachable snare is a safe and effective tool for endoscopic ligation, offering high rates of hemostasis.
- It facilitates the endoscopic resection of large elevated lesions by preventing post-procedural bleeding.
- The device is also valuable for controlling active hemorrhage during endoscopic procedures.
