A novel polyp retrieval bag reduces the polyp fragmentation rate in colon polypectomy: a single-blind randomized...

Area of Science:

• Gastroenterology
• Endoscopic Procedures
• Surgical Innovation

Background:

• Polyp fragmentation during endoscopic resection can hinder complete removal confirmation.
• Accurate confirmation of complete polyp resection is crucial for patient management and surveillance.

Purpose of the Study:

• To evaluate the feasibility of a novel polyp retrieval bag in reducing colon polyp fragmentation.
• To assess the efficacy of the new device in improving polyp retrieval outcomes.

Main Methods:

• A randomized controlled trial involving patients with 5-15 mm colon polyps.
• Polyps in the treatment group were retrieved using a novel bag, while the control group used standard endoscopic channel retrieval.
• Fragmentation rates and retrieval success were compared between the two groups.

Main Results:

• Polyp fragmentation was significantly lower in the novel bag group (3.0%) compared to the control group (17.5%) (P=0.001).
• Retrieval failure rates were similar between groups (2.0% vs. 4.9%, P=0.442).
• No significant adverse events were reported, indicating a favorable safety profile.

Conclusions:

• The novel polyp retrieval bag is a safe and feasible tool for reducing colon polyp fragmentation.
• This device shows promise for improving the quality of polyp retrieval in endoscopic procedures.
