Incomplete polyp resection (IPR) after cold snare polypectomy (CSP) is a concern. Trainee performance during polypectomy was identified as a significant risk factor for IPR, highlighting the need for further research into prevention strategies.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Colorectal cancer prevention
Background:
- Incomplete polyp resection (IPR) is a risk factor for interval colorectal cancer (ICC).
- Cold snare polypectomy (CSP) lacks electrocautery, potentially increasing IPR risk compared to hot methods.
- Risk factors for IPR specifically after CSP are not well-established.
Purpose of the Study:
- To precisely identify risk factors for IPR following CSP.
- To inform strategies for preventing IPR after CSP procedures.
Main Methods:
- Retrospective review of 1177 colorectal polyp resections from 501 patients.
- Evaluation of lateral and deep margins for resection completeness.
- Analysis of data from Omori Red Cross Hospital (October 2017 - March 2018).
Main Results:
- 1163 polyp resections were analyzed, with 206 (17.7%) showing IPR.
- Resection performed by a trainee was a significant independent risk factor for IPR (OR 1.87).
Conclusions:
- Trainee performance is a key risk factor for IPR during CSP.
- Further prospective, randomized studies are needed to develop IPR prevention methods for CSP.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

SNAREs and Membrane Fusion
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...
