Abstract:

Background/aim: Flexible fiberoptic colonoscopy, including biopsy and polypectomy, is an important diagnostic and therapeutic instrument in many indications of gastrointestinal disorders. Furthermore, cecal intubation is a complementary factor in an accurate diagnosis. The purpose of this research was to present a large case series of colonoscopic procedures and histopathological findings in our center. Materials and methods: A total of 322 patients (141 female, 181 male) between 16 and 81 years of age who underwent colonoscopy in the endoscopy center of Dicle University Gastroenterology Clinic from January 2003 to May 2006 were reviewed retrospectively. Demographic data and colonoscopic and histopathologic findings of the lesions were recorded. The success rate was defined as intubating proximal to the initial area of impasse and entering the cecum. Results: The overall adjusted cecal intubation rate for the entire 3.5 years was 78%, and increased over the study period, with the highest adjusted rate (86.7%) in the most recent year studied. Of all patients, 49.7% had normal findings. The most frequently encountered lesions were hemorrhoids, polyps, ulcers and masses. The most common mass histopathology was compatible with adenocarcinoma, ulcer histopathology with ulcerative colitis and polyp histopathology with hyperplastic and adenoma. One perforation was observed in this series, but no mortality occurred. Conclusions: Our analysis revealed approximate cecal intubation and documentation rates that meet current guidelines. To achieve better results, new technological devices are necessary.
