Capsule endoscopy is an effective means of investigating the small bowel in patients with gastrointestinal diseases.
Computerized reports are frequently used in endoscopy.
The Minimal Standard Terminology has been promoted by endoscopy societies as the official vocabulary for endoscopy.
Dr Delvaux and colleagues designed a lexicon for capsule endoscopy reports based on the principles of the Minimal Standard Terminology.
The researchers validated lists of terms for describing findings and reasons for performing a capsule endoscopy.
The research team cross-matched the findings with the results of capsule endoscopy procedures collected during ongoing clinical studies.
A consensus-based Capsule Endoscopy Structured Terminology was developed by experts involved in capsule endoscopy studies.
The researchers reported lists of terms suitable for capsule endoscopy were designed for the various sections of an endoscopic report.
The lists of terms were correlated with the corresponding Minimal Standard Terminology lists for duodenal and intestinal endoscopy.
The results of 766 capsule endoscopy procedures were collected in an electronic case record form.
The results of the capsule endosocpy procedures were analyzed to provide lists of reasons for performing the procedures and of the findings.
The electronic case records provided only a limited number of items for each data field, along with free-text facilities.
The team analyzed only descriptions pertaining to the small bowel, and assessed a total of 766 capsule endoscopy procedures.
Lists of terms were then reviewed by 2 experts to group obvious synonyms.
The team defined the accuracy of the Capsule Endoscopy Structured Terminology beforehand as the capability to describe 90% of entries.
|The terms described more than 90 % of the reasons for performance|
The electronic case records included 824 entries as reasons for the examination in 655 capsule endoscopies, representing 122 different expressions.
After grouping of synonyms, the researchers reported that 28 expressions remained.
Among the expressions, 10 were matched with terms from the list of reasons for performing capsule endoscopy offered in the Capsule Endoscopy Structured Terminology.
The team noted that these were the most frequently used, accounting for 768 entries in this field.
The researchers observed that all electronic case records contained at least 1 description of findings.
A total of 109 capsule endoscopy procedures were classified as normal.
The researchers found that a total of 2624 entries for abnormal findings were recorded for 657 procedures.
In all, the team noted that 213 different expressions were used to describe abnormal findings.
After grouping of synonyms, 52 expressions remained.
Among these, 27 were matched with terms from the list of findings in the Capsule Endoscopy Structured Terminology, covering 2403 entries.
Dr Delvaux's team commented, “In this study, Capsule Endoscopy Structured Terminology terms were capable of describing more than 90 % of the reasons for performance and of the findings in an unselected set of capsule endosocpy procedures.”
“Capsule Endoscopy Structured Terminology is therefore suitable for use as the standard lexicon for capsule endoscopy reports.”
“Adopted as a standard, it could significantly improve the quality of the data collected and reported in capsule endoscopy studies.”
