Summary Background : The effect of ageing on oesophageal motility in patients with achalasia is not well described. Oesophageal contraction amplitude is decreased in otherwise healthy elderly subjects. Aim : To evaluate whether ageing influences the motor function of the oesophagus in achalasia. Methods : Initial manometry studies of patients with achalasia were reviewed and findings (lower oesophageal sphincter basal and residual pressures and oesophageal body contraction amplitudes) were compared between two groups of patients, those 65 years of age or older (49 patients) and those younger than 65 years (68 patients). The older group was further divided into those ≥70 years and those <70 years. Results : Patients 65 years and older had significantly higher lower oesophageal sphincter basal pressures compared with younger patients (65.6 ± 4.9 vs. 52.3 ± 2.7, P = 0.02). At an age cut‐off of 70 years, older patients had significantly higher basal (70.7 ± 1.6 vs. 53.0 ± 2.4, P = 0.02) and residual (19.7 ± 1.6 vs. 15.9 ± 0.7, P = 0.03) lower oesophageal sphincter pressures compared with younger patients. Amplitude of oesophageal contractions was not different between the groups. Across all age groups, there was no linear correlation between age and basal or residual lower oesophageal sphincter pressures ( r = 0.28 and 0.12, respectively). Conclusions : Older patients with achalasia have higher lower oesophageal sphincter pressures, however there is no linear correlation between age and lower oesophageal sphincter pressures. Unlike healthy subjects, advanced age is not associated with a decrease in oesophageal contraction amplitude in patients with achalasia.
