Colorectal Polyps and Polyposis Syndromes

Abstract

Colorectal polyps are mucosal growths that protrude into the lumen of the colon or rectum and vary in histologic type, morphology, and malignant potential. Histologic categories include hyperplastic, inflammatory, hamartomatous, and neoplastic lesions. Sessile polyps emerge directly from the mucosa, while pedunculated polyps are connected by a fibrovascular stalk. This macroscopic categorization reflects morphology. Due to their potential for malignant transformation and their function as antecedents to the majority of colorectal malignancies, neoplastic polyps—especially adenomas—have the highest clinical significance. Age-related increases in incidence make screening and surveillance crucial for early detection and prevention. A crucial tactic for halting the development of adenoma into carcinoma is colonoscopy, which allows for the direct visualization, biopsy, and removal of polyps.

Through a thorough examination of etiopathogenesis, classification schemes, diagnostic techniques, and evidence-based management approaches, this educational exercise enhances the clinician's capacity to assess and treat colorectal polyps. Participants learn about risk factors, screening guidelines, and how to recognize inherited polyposis syndromes such Peutz-Jeghers syndrome, Lynch syndrome, familial adenomatous polyposis, and juvenile polyposis. The focus on working together with gastroenterologists, surgeons, pathologists, genetic counsellors, nurses, and other members of the interprofessional team emphasizes coordinated screening, precise diagnosis, genetic risk assessment, and suitable surveillance, all of which improve patient outcomes and early detection.
