Background: The data on the prevalence and distribution of polyps in Asians is limited with conflicting data about the most common type.
Objective: To obtain recent data about the histologic types of endoscopically labeled as polyps by colonoscopy and correlate with the clinico-pathologic profile.
Method: Retrospective cross-sectional review of histopathologic and endoscopic reports of colonoscopy with biopsy of colonic polyps of patients in the University of Santo Tomas Hospital (January 2014- December 2016).
Results: 3910 colonoscopies were performed and a total of 302 patients were retrieved and 500 polyps were resected. The most common indication was hematochezia and hemorrhoids. The colonic polyps were solitary in 36% of the cases. Majority were seen in 50-69 years old, left sided region (78%), particularly the sigmoid (37%), and sessile (77.3%). The most common type is tubular adenoma (45%) and majority of the adenomatous polyps were seen in the sigmoid. There is significant association between age and presence of an adenomatous polyp where ≥70 years old are about 2.5 times more likely to have adenomatous polyp and pedunculated polyps are 2 times more likely to be adenomatous. There is no significant association between presence of an adenomatous polyp and polyp size and gender.
Conclusion: The type and distribution of colorectal polyps are similar with others and vigilant approach of the left side should be exercised. Absence of any significant difference between size and adenomatous nature necessitate the need for early identification and removal of colorectal polyp in preventing morbidity and mortality from cancer.
