The influence of body mass index on colonoscopy examination
Objective To observe the impact of body mass index(BMI)on colonoscopy.Methods 299 patients who underwent colonoscopy in our hospital from December 2021 to June 2022 were selected.Based on their BMI,these patients were categorized into underweight group(BMI<18.5 kg/m2,n=30),normal group(18.5 kg/m2≤BMI<24 kg/m2,n=188),overweight group(24 kg/m2≤BMI<28 kg/m2,n=45)and obesity group(BMI≥28 kg/m2,n=36).Differences in relevant indicators such as cecal intubation rate,endoscopy time,intestinal cleanliness(BBPS score)and access difficulty(operator score)of patients between groups were analyzed.Results In the Underweight group,the cecal intubation rate is 93.33%,with good intestinal preparation,longer endoscopy time,higher operator score,and increased procedural difficulty.In the normal group,the cecal intubation rate is 100%,In the Overweight group,the cecal intubation rate is 100%,with longer endoscopy time,lower operator score,reduced procedural difficulty,and suboptimal intestinal preparation.In the obesity group,the cecal intubation rate was 97.22%,with poor intestinal preparation,longer endoscopy time,the highest operator score,and the most difficult operation.Conclusion Patients with normal weight or overweight have less difficulty in colonoscopy and good intestinal cleanliness.Patients with low weight or obesity have greater difficulty in colonoscopy and poor intestinal cleanliness.Therefore,it is advisable to develop a more tailored intestinal cleansing plan based on the patient's BMI prior to colonoscopy in order to enhance the safety and quality of the procedure.
