BACKGROUND & AIMS: Although the "submucosal cushion" technique or injection-assisted polypectomy (IAP) is often used to resect colon polyps, little is known on the influence of this technique on histologic interpretation. We aimed to evaluate whether the use of a submucosal cushion improves the histologic and margin evaluation of colon polyps.
Consecutive patients undergoing polypectomy with and without IAP were included. An experienced blinded gastrointestinal pathologist evaluated the specimens using standardized criteria.
One hundred eleven sessile colon adenomas were analyzed (IAP, n = 65, standard, n = 46). Two-thirds of polyps ranged in size from 10 to 20 mm; the average polyp size was 13.2 mm for IAP and 9.9 mm for standard snare polypectomy (P = .001). The cautery degree, cautery amount, and margin evaluability, did not differ substantially with regard to the resection technique. For polyps ≥10-20 mm, the overall architecture quality was better in polyps resected with standard technique as compared with IAP.
The utilization of IAP did not result in a better margin evaluability of the resected polyp. Overall, IAP does not result in a better histologic polyp evaluability.
尽管“黏膜下垫”技术或注射辅助息肉切除术（IAP）常用于切除结肠息肉，但对于该技术对组织学解释的影响知之甚少。我们旨在评估黏膜下垫的使用是否会改善结肠息肉的组织学和切缘评估。
纳入了接受 IAP 和无 IAP 息肉切除术的连续患者。一位经验丰富的盲法胃肠病学病理学家使用标准化标准评估标本。
分析了 111 个无蒂结肠腺瘤（IAP，n=65，标准，n=46）。三分之二的息肉大小在 10 至 20 毫米之间；IAP 和标准圈套息肉切除术的平均息肉大小分别为 13.2 毫米和 9.9 毫米（P=0.001）。切除技术方面，电凝程度、电凝量和切缘可评估性没有明显差异。对于≥10-20 毫米的息肉，与 IAP 相比，标准技术切除的息肉整体结构质量更好。
IAP 的使用并未导致切除息肉的切缘可评估性更好。总体而言，IAP 并不会导致更好的组织学息肉可评估性。
