Polyp Resection - Controversial Practices and Unanswered Questions

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Oncology

Background:

• Colorectal cancer (CRC) screening relies on detecting and removing precancerous polyps.
• Neoplastic polyps are highly prevalent (>50%) in screening populations, but most do not progress to cancer.
• Diminutive polyps (≤5 mm) constitute 70-80% of polyps and rarely harbor cancer, questioning their clinical significance.

Purpose of the Study:

• To explore controversies and emerging concepts in endoscopic polyp resection.
• To discuss the management of diminutive polyps and the potential shift towards focusing on larger, higher-risk polyps.
• To review evidence on optical resect-and-discard strategies, cold snare resection for larger polyps, and prophylactic clipping.

Main Methods:

• Literature review of recent studies and current evidence.
• Discussion of challenges and alternatives in endoscopic polyp management.
• Analysis of controversies in polyp resection strategies.

Main Results:

• The "resect-and-discard" strategy faces challenges, necessitating exploration of alternatives.
• Evidence supports cold snare resection for polyps ≥5 mm.
• Current evidence on prophylactic clipping after large polyp resection is examined.

Conclusions:

• The management of diminutive polyps warrants re-evaluation due to questionable benefits and potential harms.
• A shift in focus towards detecting and removing larger, higher-risk polyps may be beneficial.
• Further study is needed on optimizing endoscopic polyp resection techniques and strategies.
