The Success Rate of Unsedated Colonoscopy Examination in Adult

Aim: . Aim of the study was to evaluate the feasibility of unsedated colonoscopy examination in the increasing trend of deep sedation colonoscopy examination in our countryMaterial & Methods: The endoscopy reporting system images of single-handed (one-man) method unsedated colonoscopy examinations were evaluated. Patients with history of colorectal surgery were excluded from the analysis.. We evaluated the success rate of caecal intubation by unsedated colonoscopy. Non parametric binomial test was applied for statistical analysis with p <0.05Results : There were 244 patients included in the study with 143 (82.66%) patients caecal intubated seccessfully(success group) and 30 (17.34%) patients failed to reach the caecum due to severe abdominal pain only(failure group) (p<0.0001). The lesions that obstructed the colonoscopy examination were 38 distal colon cancers, 9 proximal colon cancers, and 4 colon strictures. Eight patients with unfinished colonoscopy examination due to haemodynamic worsening, and 12 patients with unfinished colonoscopy examination due to bad bowel preparation (fecal obstruction). The success rate of endoscopic diagnosis confirmation was 86.61%(194) vs 13.39%(30) (p<0.0001). No complication or mortality was found in this study.Conclusion : the unsedated colonoscopy is still significantly feasible procedure for colon examination.
