Patients and methods
The study was approved by the Institutional Review Board at Indiana University Purdue University Indianapolis/Clarian Health Partners.
A total of 519 consecutive polyps were identified by a single experienced colonoscopist (D.K.R.), who performed polypectomy with hot snare, cold snare, or cold forceps. The study colonoscopist does not use hot forceps for polypectomy. A total of 400 polyps were selected for cold snaring, based on their size and shape. The study colonoscopist typically uses cold
Results
A total of 519 consecutive polyps in 167 patients were resected during the study interval, with 400 polyps (77%) removed by cold snare. The estimated locations and pathologic findings of the 400 polyps removed by cold snaring are shown in Table 1. Of the polyps transected by cold snare, those removed by method A had a mean size of 3.7 mm, and the polyps removed by method B had a mean size of 3.4 mm (p = 0.16). No complications were observed with cold snare transection. Of the 119 polyps removed
Discussion
In this study, we evaluated two different methods of resecting and retrieving polyps with cold snare resection. Both methods were highly effective for polyp retrieval. One method consisted of snare resection without tenting the polyp, followed by suctioning the polyp (by moving the suction channel up to the polyp as it is seen in the endoscopic field), and was a more efficient method of polypectomy. The explanation for the superiority of this method appears to be that the polyp sticks to the
