Correlation of Cleanliness among Different Bowel Segments during Colonoscopy: A Retrospective Study

Abstract

Objective. To analyze the correlation of intestinal cleanliness in each segment of the Boston Intestinal Preparation Scale. Methods. From February 2017 to October 2019, the data of patients who underwent colonoscopy in the Department of Gastroenterology, Hangzhou First People’s Hospital, Zhejiang University School of Medicine, were collected. Statistical analysis was performed according to the Boston Intestinal Preparation Scale score, and the correlation of intestinal cleanliness in each region was obtained. Results. A total of 1739 patients were included. The overall score of BBPS was 6.77±1.88. The scores of each region were 2.04±0.84 (right lateral colon), 2.25±0.68 (transverse colon), and 2.48±0.64 (left colon). The difference between the regions was statistically significant (P<0.05). The bowel cleanliness showed a gradual deterioration trend, and there was a positive correlation between colon cleanliness in each region. The accuracy of the transverse colon in predicting the right colon (AUC=0.809) is higher than that of the left colon (AUC=0.735), and the accuracy of predicting the cleanliness of the right colon intestinal tract by the cleanliness of the left colon intestinal tract is relatively low. Conclusion. Intestinal cleanliness gradually deteriorates from the direction of the insert. It is not reliable to predict the right side of poor cleanliness by using the left colon intestinal cleanliness (BBPS 0-1 score). It should continue to further endoscopy. When the cleanliness of the transverse colon is poor, then stopping further endoscopy is considered.

Effect of Compound Polyethylene Glycol Electrolyte Powder on the Quality of Gastrobowel Preparation before Enteroscopy Intervention

“…e study shows that good bowel cleanliness can greatly improve the inspection e ect of enteroscopy [3]. Traditional bowel preparation is mainly based on oral senna 3 days before operation and 20% mannitol catharsis before operation.…”

“…The examining doctor can observe the smallest changes of the mucosa at the enteroscopy, but the clarity of the image mainly depends on the bowel cleanliness of the patient [ 2 ]. The study shows that good bowel cleanliness can greatly improve the inspection effect of enteroscopy [ 3 ]. Traditional bowel preparation is mainly based on oral senna 3 days before operation and 20% mannitol catharsis before operation.…”

Correlation between prescribing doctor attributes and intestinal cleanliness in colonoscopy: a study of 22522 patients

“…The risk of colonoscopy-related complications, such as excessive bleeding or puncture wounds, increases with repeated endoscopies. Abandoning endoscopy could lead to legal repercussions and increase the risk of undiagnosed intestinal lesions [ 43 ]. Our research findings indicate that the overall BBPS score was 6.83 ± 1.94, which was relatively high compared to data from the BBPS score of the Research Center at Boston Medical Center (6.2 ± 1.5) [ 29 ].…”

Bowel preparation prior to colonoscopy with a new colonic irrigation device: Results of a prospective observational study

“…In studies using colonic irrigation before colonoscopy, segmental BBPS scores vary, between 2.1 and 2.5 [13,[28][29][30][31][32] for the RC, between 2.6 [13] and 2.74 [32] for the TC, and between 2.6 [13] and 2.81 [32 for the LC. In studies using oral preparation before colonoscopy, segmental BBPS scores vary depending on which oral agent was used, between 2.04 [31] and 2.67 [27] for the RC, between 2.25 [31] and 2.73 [27] for the TC, and between 2.48 [31] and 2.79 [27] for the LC. A segmental BBPS score < 2 for the RC (1.78) was reported by Manes et al [29] in patients receiving sodium picosulfate plus magnesium citrate (PMC) as standard dose (two sachets taken the day before endoscopy).…”

“…The mean segmental score for RC was 2.4 ± 0.69, for TC 2.7 ± 0.61 and for LC was 2.7 ± 0.55. In studies using colonic irrigation before colonoscopy, segmental BBPS scores vary, between 2.1 and 2.5 [13,[28][29][30][31][32] for the RC, between 2.6 [13] and 2.74 [32] for the TC, and between 2.6 [13] and 2.81 [32 for the LC. In studies using oral preparation before colonoscopy, segmental BBPS scores vary depending on which oral agent was used, between 2.04 [31] and 2.67 [27] for the RC, between 2.25 [31] and 2.73 [27] for the TC, and between 2.48 [31] and 2.79 [27] for the LC.…”
