Study on the effect of bowel preparation protocol on the efficiency of colonoscopy based on Bristol stool characters typing
Objective To investigate the effect of bowel preparation protocol on the efficiency of colonoscopy based on Bristol stool characters typing.Methods A randomized controlled trial was conducted on 88 patients scheduled for colonoscopy at the Second Affiliated Hospital of Xi'an Medical University from October 2020 to September 2022.The patients were divided into an observation group(44 cases)and a control group(44 cases)using the random number table method.In the control group,there were 22 males and 22 females,aged(48.71±3.44)years.In the observation group,there were 21 males and 23 females,aged(48.55±3.40)years.The control group received standard bowel preparation protocol,while the observation group received bowel preparation protocol based on Bristol stool characters typing.The success rate of bowel preparation,colon cleanliness[Boston Bowel Preparation Scale(BBPS)],colonoscope insertion time,and overall examination time were compared between the two groups after receiving different bowel preparation schemes.t test and x2 test were used.Results The qualified rate of bowel preparation in the observation group was higher than that in the control group[79.55％(35/44)vs.47.73％(21/44)],with a statistically significant difference(x2=9.625,P=0.002).The BBPS scores for the right,middle,and left colon sections of the observation group were higher than those of the control group[(2.11±0.69)points vs.(1.71±0.52)points,(2.31±0.48)points vs.(1.95±0.57)points,(2.29±0.47)points vs.(1.99±0.67)points],and the colonoscope insertion time and overall examination time were shorter than those of the control group[(11.20±0.85)min vs.(11.62±1.05)min,(15.17±1.24)min vs.(16.28±1.73)min],with statistically significant differences(t=3.071,P=0.003;t=3.205,P=0.002;t=2.432,P=0.017;t=2.062,P=0.042;t=3.459,P=0.001).Conclusion Bowel preparation protocol based on Bristol stool characters typing significantly optimizes the efficiency and quality of colonoscopy by improving the success rate of bowel preparation and colon cleanliness,as well as reducing the colonoscope insertion time and overall examination time,offering a more effective bowel preparation method for clinical practice.
