Summary

Cold snare polypectomy is a common method for removing small colorectal polyps. A specific mucosal defect, the wick sign, may appear after this procedure but does not indicate residual polyp or complications.

Area of Science:

Gastroenterology
Endoscopic Surgery

Background:

Cold snare polypectomy (CSP) is the preferred method for resecting small colorectal polyps.
Endoscopic surveillance is crucial for detecting and managing colorectal polyps.

Observation:

A distinct mucosal defect, termed the 'wick sign,' can be observed following CSP.
This sign is characterized by a specific visual appearance of the mucosal defect.

Findings:

The wick sign does not represent residual polyp tissue after successful resection.
The presence of the wick sign is not associated with adverse outcomes or complications.

Implications:

Accurate identification of the wick sign is essential for endoscopists.
Recognizing the wick sign prevents unnecessary interventions and reassurances patients.
