Abstract: Bidirectional endoscopy (BE) is often used to assess patients for the reason of anemia or to screen asymptomatic
population for malignancy. Limited clinical data favors to perform first the upper gastrointestinal system endoscopy, but its effect to the
duration of colonoscopy is yet to be determined. The aim of this retrospective study is to evaluate the effect of upper gastrointestinal
system endoscopy on the time to achieve cecal intubation during colonoscopy in patients undergoing BE. Patients of four endoscopists
at similar experience levels were retrospectively identified and categorized into the upper gastrointestinal system endoscopy before
colonoscopy group (group 1) or the colonoscopy only group (group 2). The demographics, clinical data and the time to achieve cecal
intubation for each patient were analyzed. The mean time to achieve cecal intubation in the first group that included 319 cases was 8.4
± 0.93 minutes and the mean time in the second group that included 1672 cases was 8.56 ± 1.16 minutes. There was no statistically
significant difference between the groups. There was also no significant difference between the Group 1 and Group 2 when compared
according to which of the four endoscopists performed the procedures. Performing the upper gastrointestinal system endoscopy prior
to colonoscopy did not affect the time to achieve cecal intubation. Considering that performing the upper gastrointestinal system
endoscopy prior to the colonoscopy is more advantageous in terms of patient comfort and analgesic requirement, beginning to BE with
it seems more favorable. (IJCEM1306014).
