Objective: Although radiological imaging modalities like barium enema and computed tomography provide some clues, endoscopic methods still maintain superiority in assessment and differential diagnosis of large intestinal symptoms and complaints that require biopsy. We aimed to present the results of colonoscopic procedures performed in our Endoscopic section of Medicine department in detail. Material and Methods: 2169 patients who presented to Endoscopy section of Department of Medicine between May 2015 and November 2018 with an indication for colonoscopy and sigmoidoscopy were retrospectively evaluated. Results: Out of the 2169 patients enrolled in the study 1739(80.2%) were male while 430 patients (19.8%) were female. The mean age of the patients was found to be 49 years. Results of colonoscopies performed on 2169 patients in our study revealed malignancy in 207 (9.5%) patients.Mortality were not observed in this study. No post procedure–related complications were seen in our study.The complication rate in our series was nil.
