Difficult colon polypectomy.

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Oncology

Background:

• Colorectal cancer (CRC) is a major global health concern, with 90% originating from adenomatous polyps.
• Polypectomy significantly reduces CRC incidence, with most polyps removed endoscopically.
• Advanced polypectomy techniques address challenging polyps that pose risks during resection.

Purpose of the Study:

• To define criteria for identifying difficult colon polyps.
• To provide practical tips and tricks for advanced polypectomy techniques.
• To emphasize the importance of training and supervision for managing complex polyps.

Main Methods:

• Review of current literature on colorectal polyp management.
• Definition of 'difficult polyp' based on size, shape, and location.
• Discussion of advanced endoscopic resection strategies.

Main Results:

• Difficult polyps are characterized by large size (>15 mm), large pedicles, flat/extended morphology, poor visibility, or unfavorable locations.
• Advanced resection techniques, while successful, carry risks of serious complications, especially with difficult polyps.
• Supervision and expert training are crucial for endoscopists performing advanced polypectomy.

Conclusions:

• Effective management of difficult colon polyps requires specialized techniques and expertise.
• Minimizing complications associated with advanced polypectomy is paramount.
• Continuous training and adherence to safety protocols are essential for successful outcomes in interventional endoscopy.
