Esophageal high-resolution manometry demands visual interpretation in addition to mathematical software-based analysis.

Purpose: Esophageal high-resolution manometry (HRM) revolutionized esophageal function testing due to the intuitive colorful and agreeable-to-the-eyes plots (Clouse plots). HRM execution and interpretation is guided by the Chicago Classification. The well-established metrics for interpretation allows a reliable automatic software analysis. Analysis based on these mathematical parameters, however, ignores the valuable visual interpretation unique to human eyes and based on expertise.
Methods: We compiled some situations where visual interpretation added useful information for HRM interpretation.
Results: Visual interpretation may be useful in cases of hypomotility, premature waves, artifacts, segmental abnormalities of peristalsis, and extra-luminal non-contractile findings.
Conclusion: These extra findings can be reported apart from the conventional parameters.
