Factors effecting cecal intubation time during colonoscopy

Abstract

AIM: The aim of this study is to evaluate the factors that has an effect on Cecal Intubation time (CIT), and to define the relationship between quality of bowel preparation and body mass index (BMI).

PATIENTS METHODS: The Boston Bowel Preparation Scale (BBPS) was used for the evaluation of bowel cleansing. A total of 346 patients were included. The time from anus to caecum was recorded as the time of the cecal intubation time. Patients were defined under 3 subgroup BMI-1; ≤ 24.9, BMI-2; 25-29.9, BMI-3; ≥30.

RESULTS: The mean BMI of women was 29.30±4.25 and men were 26.19±6.14 (p<0,001). Mean Cecal Intubation time was 9.11±6.00 and 10.21±3.45 minutes for women and men (p=0.012). Women with High BMI (≥30) have shorter Cecal Intubation time compared to women with BMI less than 30 (p=0001). When BBPS evaluated, there was a significant difference in BMI-3 due to high scores compared to both BMI-1 and BMI-2 (p<0.001). In BMI-3 group, also women had significantly higher scores in terms of BBPS(p=0.006). Also a negative correlation between BBPS and BMI with CIT has been found (r = – 0.371, p<0.001 / r = –0.191 p<0.001).

CONCLUSION: In our study, women gender and increased BMI has a positive impact on the quality of intestinal cleansing that is associated with shortened Cecal Intubation time.
