Does this patient have oesophageal motility abnormality or pathological acid reflux?Hong SN, Rhee PL, Kim JH, Lee JH, Kim YH, Kim JJ, Rhee JC Division of Gastroenterology, Department of Medicine, Samsung Medical Centre, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea. BACKGROUND AND AIMS: The diagnostic values of particular symptoms centred on oesophagus, among patients with suspected oesophageal motility abnormality or pathological acid exposure, are not yet fully understood. The aim of this study was to determine the predictive accuracy of these symptoms in diagnosis of oesophageal motility disorder or pathological acid exposure. PATIENTS AND METHODS.: A total of 462 patients who had undergone conventional oesophageal manometry and ambulatory 24-h pH monitoring to investigate a clinical suspicion of oesophageal motility disorder and pathological acid exposure were enrolled in this study. According to their principal complaints, the patients were divided into the dysphagia category, the non-cardiac chest pain category, the gastrooesophageal reflux disease-related symptom category and the extraoesophageal symptom category. RESULTS: Two hundred and two (44%) out of 462 patients yielded abnormal findings on manometry and/or pH monitoring. Dysphagia was associated with a likelihood ratio (LR) of 2.11 [95% confidence interval (CI), 1.02-4.00)] in patients exhibiting a combination of oesophageal motility abnormality and pathological acid exposure. During oesophageal manometry, the dysphagia substantially increased the likelihood of classic achalasia (LR, 6.24; 95% CI, 3.32-8.78) and diffuse oesophageal spasm (LR, 3.58; 95% CI, 1.03-7.12). When the patients with dysphagia were divided into two groups according to the severity of their symptoms, classic achalasia was significantly frequent in patients with severe dysphagia (P = 0.016). On the other hand, non-cardiac chest pain was the clinical factor that reduced the likelihood of classic achalasia (LR, 0.22; 95% CI, 0.04-0.93). The distribution of pathological acid exposure was significantly frequent between the groups of patients with and without gastrooesophageal reflux disease-related symptom (P = 0.011). CONCLUSION: A small number of oesophageal symptoms are helpful in predicting the likelihood of abnormal findings on oesophageal tests among patients with a clinical suspicion of oesophageal motility disorder and pathological acid exposure. The most useful finding is a severe dysphagia, which is likely to have classic achalasia. Published 24 June 2005 in Dig Liver Dis, 37(7): 475-84.
