Bowel preparation quality scales for colonoscopy

Abstract

Colorectal cancer (CRC) is the third most common cancer and second leading cause of cancer-related death in the United States. Colonoscopy is widely preferred for CRC screening and is the most commonly used method in the United States. Adequate bowel preparation is essential for successful colonoscopy CRC screening. However, up to one-quarter of colonoscopies are associated with inadequate bowel preparation, which may result in reduced polyp and adenoma detection rates, unsuccessful screens, and an increased likelihood of repeat procedure. In addition, standardized criteria and assessment scales for bowel preparation quality are lacking. While several bowel preparation quality scales are referred to in the literature, these differ greatly in grading methodology and categorization criteria. Published reliability and validity data are available for five bowel preparation quality assessment scales, which vary in several key attributes. However, clinicians and researchers continue to use a variety of bowel preparation quality measures, including nonvalidated scales, leading to potential confusion and difficulty when comparing quality results among clinicians and across clinical trials. Optimal clinical criteria for bowel preparation quality remain controversial. The use of validated bowel preparation quality scales with stringent but simple scoring criteria would help clarify clinical trial data as well as the performance of colonoscopy in clinical practice related to quality measurements.

Expert endoscopists with high adenoma detection rates frequently detect diminutive adenomas in proximal colon

“…The bowel preparation scale of this study was not a gold standard. We should have used Boston Bowel Preparation Scale or Aronchick Scale, which are international standards [42]. Studies should be planned to address these aspects and corroborate our findings.…”

A Randomized, Endoscopist-Blinded, Prospective Trial to Compare the Efficacy and Patient Tolerability between Bowel Preparation Protocols Using Sodium Picosulfate Magnesium Citrate and Polyethylene-Glycol (1 L and 2 L) for Colonoscopy

“…In a follow-up study, we plan to devise ways to confirm the patients' past bowel preparation methods to allow a more meaningful comparative analysis. Additionally, as BBPS is a validated tool for postwash scoring, it would have been better to use a prewash scoring system, such as the Aronchick Bowel Preparation Scale, along with the BBPS [27][28][29][30].…”

Efficacy and Patient Tolerability Profiles of Probiotic Solution with Bisacodyl Versus Conventional Cleansing Solution for Bowel Preparation: A Prospective, Randomized, Controlled Trial

“…The efficacy profiles of the bowel preparation agents were evaluated using the bowel cleansing quality, polyp detection rate, and adenoma detection rate. The quality of bowel cleansing was determined using the Ottawa scale system [ 41 ]. The Ottawa scale was constructed with the degree of cleaning segment of the colon (left colon, transverse colon, and right colon) and the amount of fluid in the entire colon [ 41 ].…”
