Colorectal Sessile Serrated Lesion and Synchronous Neoplasm or Polyps: An Update and Critical Assessment;Analysis of 167 Consecutive Cases Undergoing Total Colonoscopy and Found 343 Polyps

Aim: Sessile serrated lesions (SSL) have the potential for malignant transformation into colorectal carcinoma (CRC), which develops via pathway of carcinogenesis. Material and Methods: Based on colonoscopy pathology reports, all sessile or polyps in risk screening group were studied at an urban medical research center between July 2018 2022. We prospectively included consecutive classified as a hyperplastic polyp (HP), lesion (SSL), traditional adenoma (TSA), unclassified adenoma, synchronous neoplasm polyp. Results: During 48-month study period, 167 cases diagnosed. In study, 97 (58.1%) patients male, 70 female (41.9%), mean age was 59.74 (± 11.1). Hematoxylin-eosin preparations available complete analysis 226 SSL, 117 had adenomatous carcinomas. Approximately 88.1% ≤10 mm less diameter. There significant correlation size (≤10 mm) epithelial (p=0.000). particular, detected sigmoid colon with rectum relatively larger than other locations. The most common locations our study. association anatomical distribution follows; HP frequently observed 57.7% (194 polyps), SSL 6.8% (23 TSA 2.1% (7 0.6% (2 cases), conventional seen 31% (104 polyps) polyps, three (0.9%) Conclusions: Hyperplastic are lesions, tubular adenomas commonly accompanied by polyps. HPs distal colon, particularly rectum. Future prospective studies using uniform diagnostic criteria considering clinical outcomes needed to make accurate decisions regarding surveillance treatment lesions.
