Abstract
BACKGROUND: Achalasia cardia is usually treated by pneumatic dilation or surgical esophagomyotomy. The role of esophageal manometry for objective assessment of symptom response is controversial. AIM: To study the relationship between symptoms and manometric parameters before and after pneumatic dilation in patients with achalasia cardia.
METHODS: Sixteen patients with achalasia cardia underwent esophageal manometry before and after undergoing pneumatic dilation. At each time, lower esophageal sphincter (LES) pressure and mean basal esophageal-gastric pressure gradient (MIEP-MIGP) were measured.
RESULTS: Good symptom response was obtained in 12 of 16 patients. Median (range) LES pressure fell from 42 (17-51) mmHg to 18 (8-39) mmHg in those patients with a good response, and from 51 (25-68) mmHg to 29.5 (23-42) mmHg in those who responded poorly. Mean intraesophageal pressure fell below mean intragastric pressure in both the groups.
CONCLUSIONS: Esophageal manometry does not correlate with symptom improvement after pneumatic dilation in achalasia cardia. Dysphagia may persist in spite of reversal of the MIEP-MIGP gradient.
