Abstract

Sessile serrated lesion (SSL) with dysplasia is an accelerated phase toward invasive carcinoma, hence requiring closer followup in post-polypectomy surveillance plans. Conventional intestinal type dysplasia, such as tubular adenoma (TA), is one of the several forms of dysplasia seen in SSL, and it is recommended not to be graded. Likewise, calling such polyps ‘Mixed polyp with SSL and TA’ has been discouraged. To investigate the adherence of pathologists to new the terminology of SSL with dysplasia and how their reports may affect post-polypectomy surveillance by gastrointestinal specialists, we designed two separate surveys for both groups. Our survey showed that 69% of pathologists do grade SSL with dysplasia, and 61.5% still use the term ‘Mixed polyp with SSL and TA’. Responses from gastrointestinal specialists showed that 56% have different follow-up plans based on the grading of dysplasia in SSL, and 22% have different follow-up plans for SSL with dysplasia versus ‘Mixed polyp with SSL and TA’. Conclusions: The grading of dysplasia and the term ‘Mixed polyp with SSL and TA’ are still being used today, which affects postpolypectomy follow-ups.
