Background and AimsThe American Society for Gastrointestinal Endoscopy recommends that distal colon hyperplastic lesions can be left in place without resection if adenomatous histology can be excluded with >90% negative predictive value. However, some lesions could be sessile serrated adenomas/polyps (SSA/Ps), which is also precancerous. The aim of this study was to describe the prevalence of SSA/Ps in hyperplastic-appearing diminutive rectosigmoid polyps.MethodsWe prospectively placed 513 consecutive diminutive rectosigmoid polyps that appeared hyperplastic to an expert endoscopist in individual bottles for pathologic. Each polyp was examined by 3 expert GI pathologists.ResultsThe prevalence of SSA/P in the study polyps ranged from .6% to 2.1%. The lowest negative predictive value found by the endoscopist for the combination of adenomas plus SSA/Ps was 96.7%.ConclusionsThe prevalence of SSA/Ps in diminutive rectosigmoid hyperplastic-appearing polyps is very low. These results support the safety and feasibility of a “do not resect” policy for diminutive hyperplastic-appearing rectosigmoid polyps.
