Summary
The esophageal egg transit test (OET) effectively screens for esophageal motility disorders, correlating well with manometry. This objective test identifies specific disorders with high predictive value, recommending its use before manometry.
Area of Science:
- Gastroenterology
- Nuclear Medicine
- Diagnostic Imaging
Background:
- Esophageal motility disorders present diagnostic challenges.
- Oesophageal manometry is the gold standard but can be invasive.
- A non-invasive, objective screening tool is needed.
Purpose of the Study:
- To evaluate the diagnostic value of the standardized 99mTc-labelled solid bolus oesophageal egg transit test (OET).
- To compare OET's accuracy against oesophageal manometry in symptomatic patients.
- To define OET's predictive values for specific and non-specific esophageal motility disorders.
Main Methods:
- A standardized 99mTc-labelled solid bolus oesophageal egg transit test (OET) was performed on 102 symptomatic patients.
- OET results were compared with findings from oesophageal manometry.
- Computer-generated images analyzed OET transit patterns.
Main Results:
- Abnormal OET correlated significantly with abnormal manometry (84% vs 68.8%, P < 0.001).
- OET identified five distinct transit patterns, including oscillatory, non-clearance, and delayed patterns.
- The OET showed 100% predictive value for specific motility disorders and 94% for excluding them.
Conclusions:
- The solid bolus oesophageal transit test is an objective screening tool for specific esophageal motility disorders.
- OET demonstrates high sensitivity and specificity, correlating well with manometry.
- Performing OET before oesophageal manometry is recommended for efficient diagnosis.
