Effects of body mass index on cecal intubation time in women.

OBJECTIVE

During colonoscopy, cecal intubation time is prolonged with increase in difficulty of the procedure. Cecal intubation time may be affected by age, gender, and body structure. We investigated the relationship between body mass index and cecal intubation time in women.

MATERIAL AND METHODS

This prospective study included 61 women who underwent colonoscopy in the endoscopy unit of the General Surgery Clinic in Trabzon Kanuni Training and Research Hospital between January 2016 and September 2016. The colonoscopies were performed by a single surgeon. The height and weight of all the participants were measured, and their body mass index values were calculated before the procedure. The timer was activated as soon as entry was made from the anal region with colonoscope and stopped when the cecum was reached. The cecal intubation time was recorded for each subject. The results were evaluated statistically, and p<0.05 was considered to be significant.

RESULTS

The mean body mass index was 29.6±6.8 kg/m. The median cecal intubation time was 4 min. (minimum 2 min; maximum 8 min). A significantly strong positive correlation was found between body mass index and cecal intubation time (r:-0.891, p<0.001).

CONCLUSION

Cecal intubation time was found to be shorter in women whose body mass index values were high. This outcome may help to eliminate the "the colonoscopy will be difficult" preconception, which is common among endoscopists with regard to the colonoscopies for obese female patients.
