Characteristics of Polyps in Lebanese population. International Journal of Medical Research & Review . 2023 Jan; 11(1): 1-92320-86862321-127Xhttps://imsear.searo.who.int/handle/123456789/231037Background: The objectiv e of this study is to describe the characteristics of the polyps in the Lebanese population and evaluate dysplasia and its relation to the polyps’ locations. Methods: A retrospectiv e descriptiv e study was conducted at the Department of the National Institute of Pathology in Lebanon and comprised a biopsy of colonic polyps or resected polyps from patients from 2007 to 2009. We collected demogr aphic data and polyps’ characteristics. Then, we divided patients according to age sex, location, and histology . Results: With 2298 polyps in 1470 patients, the mean age was 57.45 with 68% aged more than 50yo. 75.6% have one polyp and multiple polyps are more commonly found in older patients (> 50 years). More than 20 % of polyps are found in the recto-sig moid area. In the right colon, people older than 50 years were more likely to have polyps (19%) compared to those < 30 years (8.3%) (p < 0.05). In the rectum, people < 30 years were more likely to have polyps compared to those > 50 years (p < 0.01). Concerning histology , tubular adenoma is the most common type and is more prevalent in the left colon. Hyperplastic polyps are mainly found in the recto-sigmoid area and mainly in the age group 30-50 in contrast to adenomatous polyps found over 50yo. Adenocarcinomas and/or degener ative polyps were founded in 5.9% of our population. Conclusion: This study gives valuable information on colorectal polyps in the Lebanese population regarding age, sex, dominant histology and anatomic location. We noted a male predominance and mainly above 50 years old. The majority had single polyps, and>50% of polyps were localized in the rectosigmoid. Adenomatous polyps were the most common type.Colon polypshistologylebanonJournal ArticleIndiaAbou R ached Antoine, Lebanese university school of medicine, LebanonSanyour Joyce, MD , Lebanese univ ersity school of medicine and Sultan Qaboos Comprehensiv e Cancer Center , Muscat, OmanSaba Jow ana, MD , Lebanese univ ersity school of medicine, LebanonAbou Khalil Melissa, MD , Lebanese univ ersity school of medicine, LebanonRasha Matar , MD, Sultan Qaboos Comprehensiv e Cancer Center , Muscat, OmanKhalil Pierre, MD , Lebanese university school of medicine, LebanonKhairallah Saad, MD, Lebanese university school of medicine, lebanon.
