Abstract :Aim: Fecal occult blood test is used in the early diagnosis of colorectal cancers. We aimed to evaluate the colonoscopic and pathological findings of patients who underwent colonoscopy due to positive fecal occult blood test in a tertiary center. Material and Method: Patients who had a positive fecal occult blood test and referred to the xxx Training and Research Hospital endoscopy unit for colonoscopy were included in this study. Age, gender, colonoscopic findings and pathology results of the patients were recorded. Statistical analyzes were performed with SPSS. Results: Two hundred and twenty three patients were included in the current study. Of the patients, 101 insert ignore into journalissuearticles values(45.3%); were male and 122 insert ignore into journalissuearticles values(54.7%); were female, with a mean age of 53.2 insert ignore into journalissuearticles values(18-90 years);. Endoscopic diagnoses were as 49 insert ignore into journalissuearticles values(22%); polyps, 13 insert ignore into journalissuearticles values(5.8%); colon cancer, 4 insert ignore into journalissuearticles values(1.8%); inflammatory bowel disease, 15 insert ignore into journalissuearticles values(6.7%); diverticulum, 63 insert ignore into journalissuearticles values(28.3%); perianal disease, 79 insert ignore into journalissuearticles values(35.4%); normal colonoscopic findings. Pathological features of colon polyps were as; tubular adenoma in 51%, tubulovillous adenoma in 18.4%, serrated adenoma in 2%, and hyperplastic polyp in 28.6%. Colonoscopy findings of patients according to age groups insert ignore into journalissuearticles values(over and under 50 years of age);; the incidence of polyps insert ignore into journalissuearticles values(p=0.01); and diverticulum insert ignore into journalissuearticles values(p=0.001); were significantly higher in patients older than 50 years, while perianal diseases insert ignore into journalissuearticles values(p=0.031); and normal colonoscopic findings insert ignore into journalissuearticles values(p=0.008); were higher in patients younger than 50 years of age. Conclusion: Colon pathology was detected in approximately 2/3 of the patients presenting with a positive fecal occult blood test. This test is an inexpensive, easily applicable method that helps to detect colon cancer and precursor lesions, as well as pathologies such as subclinical inflammatory bowel disease and diverticulum causing chronic blood loss.
