Total colonoscopy is indicated in all cases of abdominal pain, nasal mucus feces, anemia, and suspected colorectal tumor through rectal exam. In the study groups, FOBT is performed before the procedure. Colonoscopy hoses entire recorded cases of endoscopic images of normal and pathological including colitis, polyps and cancer.
The research results have identified 91 out of 277 cases (32.9%) had a positive FOBT. Analysis of the results indicated FOBT by colonoscopy identified significant differences for the case of patients with or without abdominal pain (47.3 compared with 10.1%), in addition to the mucus nose (57.6 compared with 16.3%), anemia (98 compared with 18.1%). Sensitivity, specificity, positive predictive value and negative (overall and for each disease were identified by colonoscopy and the combined analysis) of FOBT with colitis, polyps and cancer Email colorectal identified by colonoscopy and the analysis combined are estimated and discussed.
