This study is the evaluation of ultrafine endoscope (with small caliber and turning radius )for colonoscopy in decreasing abdominal pain of patients . 60 patients will be accepted in this trial.
The aim of this study is to investigate the advantages of an endoscope with smaller turning radius and softer insert section in reducing patients' abdominal pain in colonoscopy. Transnasal gastroscope was selected in this study , because of its small caliber (5.9mm) and small turning radius . Visual analogue scale(VAS),cecum intubation time and cecum intubation rate were evaluated.
