Revised technique for retrieving small polyps from the colon and rectum after snare polypectomy

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Pathology

Background:

• Colonoscopic polypectomy is a key procedure for detecting and removing colorectal polyps.
• Current techniques for specimen retrieval can impact the quality of pathologic analysis.
• Improving specimen integrity is crucial for accurate diagnosis and patient management.

Purpose of the Study:

• To evaluate the efficacy of a nylon tissue biopsy bag as a refinement for snare colonoscopic polypectomy.
• To compare the nylon bag technique with a previously reported gauze pad method for specimen retrieval.
• To assess the impact of the nylon bag on specimen quality, procedural simplicity, and cost-effectiveness.

Main Methods:

• A modified snare colonoscopic polypectomy technique was employed.
• A nylon tissue biopsy bag was utilized at the suction port for specimen collection.
• The technique was compared to a prior method using a 4-inch x 4-inch gauze pad.

Main Results:

• The nylon tissue biopsy bag yielded superior pathologic specimens compared to the gauze pad method.
• The technique maintained the simplicity of the colonoscopic polypectomy procedure.
• The nylon tissue biopsy bag proved to be a cost-effective solution for specimen retrieval.

Conclusions:

• Utilizing a nylon tissue biopsy bag is an effective refinement for snare colonoscopic polypectomy.
• This method enhances the quality of pathologic specimens obtained during colonoscopy.
• The nylon bag technique offers a simple, cost-effective, and superior approach to specimen retrieval in endoscopic procedures.
