Long pediatric colonoscope versus intermediate length adult colonoscope for colonoscopy . BACKGROUND Controversy exists on how the length and diameter of colonoscopes affect the quality of colonoscopy . The aim of this study was to compare a long pediatric colonoscope with an intermediate length adult colonoscope with regards to completion rate and cecal intubation time . Whether either scope may be more efficient in any subgroups was also investigated . METHODS Asymptomatic patients admitted to the physical check-up department of Buddhist Dalin Tzu Chi General Hospital were included . A single endoscopist performed all of the colonoscopic examinations under sedation . Consecutive patients were randomized to undergo colonoscopy with either intermediate length adult colonoscope ( CF-240I ) or long pediatric colonoscope ( PCF-240L ) . The success rate and time required to reach cecum were compared between the two groups . RESULTS Between April 2005 and February 2006 , a total of 918 patients were enrolled . Incomplete colonoscopy occurred in 21 ( 2.3 % ) cases ( 14 in the CF-240I group and seven in the PCF-240L group , P > 0.1 ) . The overall cecal mean insertion time was 6.00 +/- 3.66 min . There was no significant difference between the CF-240I and PCF 240L groups with regard to the cecal intubation rate ( 96.9 % vs 98.5 % , P = 0.18 ) , the need for abdominal pressure ( 71.7 % vs 73.4 % , P = 0.55 ) and change of position ( 13.5 % vs 11.5 % , P = 0.37 ) . However , the cecal intubation time was shorter in the CF-240I group ( 5.75 +/- 3.18 vs 6.26 +/- 3.30 min , P = 0.02 ) . Subgroup analysis by sex , age , and body mass index showed comparable outcomes between the two groups except that the cecal intubation times were significantly shorter in the CF-240I group when only men ( 4.78 +/- 2.57 vs 5.50 +/- 2.93 min , P < 0.01 ) or those younger than 50 years ( 5.50 +/- 2.90 vs 6.25 +/- 3.68 min , P = 0.02 ) were considered . CONCLUSION Cecal intubation time is shorter in patients examined with an intermediate length adult colonoscope , mainly in the subgroups of men and those younger than 50 years of age .
