Abstract
BACKGROUND: We studied the spectrum of motor dysphagia in a northern Indian tertiary referral center. METHODS: In this retrospective study, consecutive patients with motor dysphagia referred to the Gastrointestinal Pathophysiology and Motility Laboratory from 2002 to 2007 were evaluated clinically and with eight-channel water-perfusion manometry. Causes of dysphagia were diagnosed using standard criteria. RESULTS: Of 250 patients (age 41.3 [15.0] years, 146 men), 193 (77%) had achalasia cardia (AC) and 57 (23%) had other causes (11, 4.4%: diffuse esophageal spasm [DES]; 9, 3.6%: hypertensive lower esophageal sphincter [Hy LES]); manometry was normal in 37 patients. Twenty-seven patients (14%) had vigorous AC. Duration of dysphagia at presentation was longer in those with AC and Hy LES than in normal manometry (NM) (21 months [1-180] vs. 6 [1-360], p = 0.000; 24 months [7-48] vs. 6 [1-360], p = 0.015). Regurgitation and bolus obstruction were more frequent in those with AC than in NM (89/154, 57.79% vs. 3/27, 11.11%, p = 0.000001). Heartburn was less frequent in patients with AC than in others (AC: 4/146, 2.73% vs. normal: 4/27, 14.8% [p = 0.02] and others: 3/15, 20% [p = 0.018]). Chest pain was reported by 74/135 (54.8%) classic and 12/19 (63.2%) vigorous AC (p = NS). Patients with NM had lower LES pressure than those with classic AC, Hy LES and vigorous AC (p < 0.0001 in each case). Patients with DES had lower LES pressure than in classic AC, Hy LES and vigorous AC (p = 0.043, p < 0.0001, and p = 0.002, respectively). Patients with classic AC had lower LES pressure than in Hy LES and vigorous AC (p = 0.024, p = 0.001, respectively). CONCLUSION: Classic AC was the commonest cause of motor dysphagia in our center. AC was associated with higher LES pressure, longer duration of dysphagia, frequent regurgitation and bolus obstruction.
