Prospective evaluation of endoscopic criteria characteristic of sessile serrated adenomas/polyps

Background Differentiating sessile serrated adenoma/polyp (SSA/P) from hyperplastic polyp (HP) is clinically important in determining the necessity of endoscopic resection or recommending appropriate surveillance. There are few reports of characterization of SSA/P using narrowband imaging and chromoendoscopy with and without magnification. We aimed to establish imaging criteria to aid real-time diagnosis of SSA/P.
