ABSTRACT
In recent years there have been noticeable changes in diagnosis and treatment of colon disorders by colonoscopy and direct vision. Along with its international development, this useful equipment is being used in Iran to treat various disorders. It should be mentioned that there are no exact statistics of these disorders to date. This study was done with aim of evaluating the diagnostic findings in patients undergoing colonoscopy in Qom during 2007-2008. This descriptive-cross sectional study was done on 500 patients having referred to colonoscopy ward of Hazrate-e-Masoome Hospital in Qom. After colonoscopy, patient data were entered into a special questionnaire and then pathologic findings were added to it. The data were taken for statistical analysis. Out of 500 patients undergoing colonoscopy 279 were male [55.8%] and 221 female [44.2%]. In all groups and both sexes the most common reason for carrying out colonoscopy was abdominal pain [46.6%] rectorrhagia [41%]. As regards diagnosis, a total of 199 cases [39.8%] of all 500 colonoscopies had normal colonoscopy,124 cases [24.8%] had hemorrhoid, 64 cases [12.8%] had polyp, 55 cases [11%] had inflammatory bowel diseases [IBD], 30 cases [6%] had tumor, 17 cases[3.2%] had diverticulosis and 12 cases [2.4%] had solitary rectal ulcer. There was a significant relationship between abdominal pain and tumor, polyp and diverticulosis. [p<0.001] There was also a significant relationship between age and the aforementioned disorders. [p<0.001] Based on the findings of this study, the prevalence of cancer and IBD is higher in men diverticulosis is higher in women. The highest prevalence of IBD was in the age group of 21-30 years. With an increase in age, the incidence rate of this disease decreases
