Esophageal capsule endoscopy showed low effectiveness and high variability for detecting short-segment Barrett's esophagus. This method is not recommended for screening this condition.
Area of Science:
- Gastroenterology
- Endoscopy
- Oncology
Background:
- Rising incidence of esophageal adenocarcinoma necessitates improved screening for Barrett's esophagus.
- Barrett's esophagus is a known precursor lesion to esophageal adenocarcinoma.
Purpose of the Study:
- To assess the utility of esophageal capsule endoscopy (ECE) in identifying short-segment Barrett's esophagus (SSBE).
Main Methods:
- Twenty patients with biopsy-proven SSBE underwent ECE.
- Images were reviewed by two independent expert observers.
- Data included transit time, image quality, and presence/absence of specific esophageal findings.
Main Results:
- ECE identified or suspected SSBE in 44% of cases by one observer and 16% by the second, indicating significant interobserver variability (P=0.14).
- Agreement on Z-line regularity was low (6/18 cases).
- Other findings like GERD, varices, or strictures were inconsistently reported.
Conclusions:
- Esophageal capsule endoscopy demonstrates high interobserver variability and low diagnostic yield for SSBE.
- ECE is not currently recommended for screening short-segment Barrett's esophagus.
