Grading systems for small-bowel cleansing for wireless capsule endoscopy

This month’s Gastrointestinal Endoscopy compares grading systems to evaluate small-bowel cleansing for wireless capsule endoscopy.

Capsule endoscopy is a powerful tool for evaluating the small bowel.

Assessment of small-bowel cleansing for capsule endoscopy is an essential quality measure.

Dr Corey Brotz and colleagues from Pennsylvania, USA validated 3 new scales that grade small-bowel cleansing for capsule endoscopy.

The team found 5 experienced capsule endoscopists read 40 capsule endoscopys twice, separated by 1 month, to grade small-bowel cleansing on 3 scales.

The 3 scales included quantitative index, qualitative evaluation, and overall adequacy assessment.

The quantitative index and qualitative evaluation evaluated both the entire and distal small bowel.

Investigators received no prior training in these scales.

There was a highly significant association among all 3 scales

The team used intraclass correlation coefficients to assess intraobserver and interobserver reliability.

The team reported that that 40 who underwent capsule endoscopy between 2005 and 2006 satisfied entry criteria.

The researchers found that intraobserver reliability was moderate to substantial for the quantitative index.

The team noted that intraobserver reliability was moderate for the overall adequacy assessment, and fair to moderate for the qualitative evaluation, and interobserver scores were lower.

Quantitative index scores for the entire and distal small bowel were highly correlated for each reader, and distal small-bowel scores were lower by 1.3 points, indicating poorer cleansing.

The team found a dichotomized qualitative evaluation of excellent/good versus fair/poor had moderate to substantial intraobserver and interobserver reliability.

There was a strong and highly significant association among all 3 scales.

Dr Brotz’s team concluded, “We have described and validated 3 scales for grading small-bowel cleansing for capsule endoscopy.”

“An evaluation of small-bowel cleansing should be routinely incorporated into the capsule endoscopy report.”
