Small bowel capsule endoscopy structured terminology

Introduction and aim: The Capsule Endoscopy Structured Terminology (CEST) has been developed following the rules established for Minimal Standard Terminology (MST) and adapted to the specific needs for the reporting of findings and diagnosis in capsule endoscopy (CE) findings. This presentation provides an overview and examples of the use of the CEST for reporting small bowel CE examination.

Structured documentation of an examination and findings: The CE examination report follows the general MST structure for endoscopic reporting. The following headings are used for the structured description of findings in the small bowel: normal, lumen, contents, mucosa, flat lesions, protruding lesions, excavated lesions.

Main headings of findings	Terms of findings
Mucosa	Erythema	Pale	Edematous	Granular	Nodular
Flat lesions	Spot	Plaque	Angiectasia
Excavated lesions	Aphta	Erosion	Ulcer	Diverticulum
Protruding lesions	Nodules	Polyps	Tumor	Venous structure

The list of diagnosis, as proposed by the CEST, is divided into two lists of terms, the main diagnosis and other diagnosis being classified according to their frequency in clinical practice.

Conclusion: The CEST supports the structured reporting of all data necessary for a CE examination, including pathological findings.
