Endoscopic polypectomy devices

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Gastrointestinal Oncology

Background:

• Gastrointestinal polyp removal is crucial for preventing colorectal cancer.
• Traditional polypectomy techniques can be challenging for certain polyp types.
• Minimally invasive endoscopic techniques are continuously evolving.

Purpose of the Study:

• To illustrate submucosal injection as an adjunct for en-bloc endoscopic mucosal resection (EMR).
• To showcase the use of a detachable loop device for hot snare resection of pedunculated polyps.
• To provide visual guidance on advanced endoscopic resection techniques.

Main Methods:

• Video 1 details submucosal injection using saline or other agents prior to en-bloc EMR.
• Video 2 demonstrates the application of a detachable loop ligating device before hot snare resection of pedunculated polyps.
• Both videos highlight key steps and technical considerations.

Main Results:

• Submucosal injection facilitates a cleaner resection plane for en-bloc EMR.
• The detachable loop device enables secure ligation and efficient removal of pedunculated polyps.
• These techniques appear to improve the ease and potentially the completeness of polyp resection.

Conclusions:

• Submucosal injection is a valuable tool for en-bloc EMR, improving specimen retrieval.
• Detachable loop ligation is an effective method for managing pedunculated polyps during endoscopic resection.
• These endoscopic techniques offer practical solutions for challenging polyp removal scenarios.
