• To evaluate oesophageal sensitivity to balloon distension in patients with non-obstructive dysphagia (NOD), and to determine its relationship with the motility pattern in response to food ingestion. Twenty-one healthy volunteers and 19 consecutive patients complaining of NOD with normal standard manometry were included. An oesophageal sensitivity test was carried out before the manometry study with liquid and solid swallows. The median threshold to distension was 9 ml in control subjects and 5 ml in patients (P < 0.002). Dysphagia or odynophagia were reproduced in 15/19 (78.9%) patients during manometry with solid swallows only. The percentage of swallows with abnormal motility patterns was higher in patients than control subjects (P < 0.001). Compared with control values, sensitivity abnormality was defined by a distension threshold of < 6 ml. Motor abnormality was defined by > 19% of swallows occurring with one or more abnormal motor profiles. A total of 8/19 (42%) patients presented with the association of an abnormal sensitivity threshold and an abnormal motor pattern; 5/19 (26%) presented with isolated motor abnormalities; 4/19 (21%) patients presented with isolated abnormal sensitivity thresholds; and 2/19 (11%) patients presented without any abnormality. Manometry with solid swallows and oesophageal balloon distension are useful in characterizing NOD.
