Aim:
This study aimed to determine whether symptoms can reliably predict a major disorder of oesophageal motility as assessed by conventional water perfusion manometry.
Methods:
Data from patients who underwent conventional water perfusion oesophageal manometry and a pre-manometry questionnaire between October 1998 and August 2018 were extracted from a database. Clinical features (dysphagia, chest pain, regurgitation, dysphagia to a bread challenge) and combinations of these clinical features were compared to manometric diagnoses.
Results:
Data from 546 patients were analysed. Thirty-three (6%) patients had a major disorder of motility, and 513 (94%) had normal manometry or a minor disorder of motility. 'Any dysphagia' (dysphagia as a symptom or dysphagia to a bread challenge) or 'chest pain' was experienced by all patients with a major disorder of motility and 435 of 513 patients with normal manometry or a minor disorder of motility (p=0.009). Sensitivity was 100%, and specificity was 15%, in identifying patients with a major disorder of motility using symptom combinations and a bread challenge.
Conclusion:
Symptoms and provoked dysphagia to bread were able to predict patients with a major disorder of oesophageal motility with a sensitivity of 100%. However, as specificity was 15%, confirmation with manometry is indicated if possible.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
