Body mass index predicts cecal insertion time: The higher, the better

Abstract

A higher BMI is strongly associated with progressively shorter CIT.

Quality of bowel cleansing in hospitalized patients undergoing colonoscopy: A multicentre prospective regional study

“…While some studies reported a low BMI as a predictor of incomplete or unsuccessful procedures, without taking bowel preparation quality into account [6,20,21], other authors [22,23] demonstrated that an excess BMI ≥25 was significantly associated with worse bowel preparation at colonoscopy, leading to a change in the recommendations after colonoscopy towards an earlier repeat procedure. Accordingly, our data demonstrate that a BMI >25 is an independent predictor of poor bowel preparation at least in the proximal colonic segments, with a 25% higher odds of being inadequately cleaned.…”

“…A prolonged runway time, the type of diet before colonoscopy (liquid or low-fibre), male gender, the use of high volume PEG solutions, non-split dose and excess BMI are considered the main factors associated with inadequate cleansing [5][6][7][8][9][10][11][12].…”

Correlation between obesity and metabolic syndrome-related factors and cecal intubation time during colonoscopy

“…Females are also considered to have less visceral fat, resulting in less tissue supporting the colon than in males thus making endoscope insertion more difficult 16. Older age was associated with longer CIT, as the elasticity of the colon decreases and loops are formed more easily with increasing age 8. Previous studies also found that patients with lower BMI were more difficult to intubate 8,9.…”

“…Not only the endoscopic operation technique of the physician, but also patient factors have been reported to affect CS difficulty. Reported CIT-related factors include sex, age, history of abdominal or gynecological surgery, body mass index (BMI), waist circumference, visceral adipose tissue, quality of bowel preparation, and involvement of fellow physicians 8–12…”
