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

Use of a nylon tissue biopsy bag at the suction port during snare colonoscopic polypectomy refines our previously reported technique in which we used a 4-inch x 4-inch gauze pad. The nylon tissue biopsy bag results in superior pathologic specimens, maintains simplicity of the technique, and is cost effective.
