INDICATIONS AND TIPS FOR DUODENAL COLD SNARE POLYPECTOMY

Abstract

The frequency of detection of superficial non-ampullary duodenal epithelial tumors is increasing in clinical practice. To date, small non-ampullary adenoma has often been observed by biopsy; however, biopsies may not be diagnostically accurate, and subsequent endoscopic resection may be challenging owing to the fibrosis after biopsies. Therefore, prompt removal is recommended for lesions that are amenable to safe and easy resection. Cold snare polypectomy (CSP) is one of the well-established standard treatments for colonic adenomas measuring ≤10mm. Notably, CSP is also an effective therapeutic strategy for management of lesions categorized as duodenal adenomas measuring ≤10mm. In this article, we outline the procedure and technical tips for duodenal CSP.
