title: How do I overcome difficulties in insertion?
abstract: Demand for colonoscopy is increasing because it is an important tool not only for screening of colorectal neoplasm but also for resection of such lesions in early stage. Cecal intubation requires expertise on shortening of the examination time and improvement of the cecal intubation rate without causing pain to the patients. About 5% to 10% of patients still experience difficulties or failure of the cecal intubation. There are number of factors that affect the difficulty of the colonoscopy such as technical skill of the endoscopist, angulated sigmoid, redundant colon, advanced age, female gender, diverticular disease, and inadequate bowel preparation. In an effort to overcome these situations and to and aiding colonoscope insertion with reducing pain, various methods have introduced. Like this review discusses ways to approach patients with technically difficult colons for achieving the successful cecal intubation.
