Endoscopic Combined Snare-Forceps Technique for Removing Flat Sessile Polyps.

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Standard endoscopic polypectomy faces challenges with flat, sessile, and broad-based polyps.
• Current limitations include single-device use and limited availability of advanced equipment in some hospitals.

Purpose of the Study:

• To describe a modified polypectomy technique for improved difficult polyp resection.
• To enhance the capabilities of endoscopists using existing colonoscope technology.

Main Methods:

• A modified technique using endoscopic forceps and snare simultaneously through a single-lumen colonoscope.
• Forceps are inserted, followed by snare placement proximal to the forceps head.
• The polyp is elevated with the snare and secured at its base.

Main Results:

• Achieved easier, faster, and more complete removal of challenging polyps.
• Successfully employed in over 20 patients, demonstrating efficacy.
• Improved first-attempt success rates for flat, sessile, and pedunculated polyps.

Conclusions:

• Presents a valuable new technique for challenging polypectomies.
• Enhances endoscopist options for difficult polyp resections.
