Esophageal motility disorders-Symptomatic and manometric spectrum in Punjab, northern India.

BACKGROUND

Data on the spectrum of esophageal motility disorders in Indian population are scarce. We aimed to study the symptomatic and manometric profile of patients with suspected esophageal motility disorders.

METHODS

Consecutive patients with esophageal symptoms who underwent esophageal high-resolution manometry (HRM) from January 2010 to December 2014 were included in this retrospective analysis of prospectively acquired data. HRM was performed with 22-channel water-perfusion system and patients classified using Chicago classification v3.0.

RESULTS

Of the 401 patients studied [median age 43 (18-85) years; 61% males], 217 presented with dysphagia, 157 with predominant retrosternal discomfort and 27 with predominant regurgitation. Among patients with dysphagia, 43.8% had ineffective esophageal motility [IEM], 26.3% had achalasia cardia [AC], 6.9% had distal esophageal spasm [DES] and 19.4% had normal manometry [NM]. Among patients with retrosternal discomfort, 42.7% had IEM, 5.7% had AC, 4.5% had DES and 42% had NM. AC was significantly more common among patients presenting with dysphagia compared to those with retrosternal discomfort [p< 0.001] or regurgitation [p< 0.001]. NM was significantly more common among patients presenting with retrosternal symptoms compared to those with dysphagia [p< 0.001]. AC patients had longer duration of dysphagia, more frequent bolus obstruction and more weight loss compared to those with IEM or NM [p< 0.05].

CONCLUSION

Dysphagia was the commonest presenting symptom followed by retrosternal discomfort. Ineffective esophageal motility (not achalasia cardia) was the commonest manometric finding both among patients with dysphagia and retrosternal discomfort. This study highlights the high prevalence of IEM among patients with esophageal symptoms, which can present with dysphagia or retrosternal discomfort due to poor bolus transit.
