Colon polyp retrieval after cold snaring

Area of Science:

• Gastroenterology
• Endoscopy
• Surgical Techniques

Background:

• Cold snare transection is an effective method for colon polyp removal with low reported complication rates.
• Concerns regarding cold snare use include immediate bleeding and polyp retrieval difficulties.
• This study aimed to evaluate polyp retrieval rates using two distinct cold snare resection and retrieval methods.

Purpose of the Study:

• To compare the efficacy of two cold snare polypectomy techniques in terms of polyp retrieval rates.
• To assess the safety and efficiency of cold snare polypectomy for small colon polyps.

Main Methods:

• A single colonoscopist performed polypectomies, with cold snare cases randomly assigned to Method A (cold resection then suction) or Method B (snare, pull through, then transect).
• Polyp size, location, and retrieval times were recorded for 400 cold-snared polyps (3.5 mm mean size).
• Histologic examination of separately collected specimens was performed.

Main Results:

• Method A achieved a 100% retrieval rate (197/197 polyps), while Method B achieved a 98% retrieval rate (199/203 polyps).
• Mean retrieval time was significantly shorter for Method A (14.5s) compared to Method B (18.1s).
• No complications were reported with either cold snare method.

Conclusions:

• Cold snare polypectomy demonstrates a high success rate for colon polyp retrieval.
• Both evaluated methods are effective, with snare transection followed by suction (Method A) being slightly more efficient.
• Concerns about polyp retrieval failure should not deter the use of cold snare polypectomy.
